CUMMINS ECM REPAIR TIPS

[makura]

Hi guys

i just wanted to open this thread to all ecm repair guys to share problems and ideas on these ecms,lets keep this open only for cummins ecm' problems and repair solutions.lets dig in and help each other out.

[BATLER]

nice thread m8,this will help us for sure!

[dafdiagnos]

the main problem seems to be when some bright spark decides to jump start these without turning lights on etc to remove power spike

[hercamp]

three differents problems that I have are

in a celect plus ecm.....has not detect the oil presure semsor signal I recalibrated and nothin.?wh?
and other celect that shut down inyectors up to 80?c and the engine cant runn up to 1500 rpm...

and other celect ecm that ...runn the engine at idle in 950 rpm....?wh?

well ....now I solved problem changing the ecm but ....the real repair can be changing internal elements.

1.- maybe the signal is going to ground or the sensor screw up
2.- Make a cutcylinder test and check if the inyectors are ok or try to change a ecm and check if the RPM still under 1500
3.- Check the parameter of idle option.

I ve seen that .....I m not very explisit ( I do all test ) and finally I change ecm and solve problem...bythe way about this is the thread ....how to repair the ecm.:beheaded:

[makura]

Hercamp try this trick,it works in most cases.

Start a calibration procedure and when your ecm is at lets say 33% upload,turn your key (ON or OFF)depending on which ecm you calibrating celect(off) celect plus (on) wait for the calib fail massage then start from scratch(on celect plus you will have to put your key on for 5seconds and off again thats how you will be able to communucate with the ecm,when you get to the part it say turn key off just click on ok since your key is already off)follow the screen promps to the end,now all the original info is lost,you trip info is back to 000 for everything,if you are using insite 7.4 you will get your parameter settings back,and if you using any thing b4 7.4 you have to do your parameters all over again.
with celect its pretty much straight forward,just put key on ,connect to ecm,rom boot message will pop up,just follow screen promps.
gooedluck,let me know if this works for you. :listen:

[hercamp]

yeah ...its works ...fine ...in retreivering of parameters also ..I cant save one but the others two ecm works ok.thanks

[makura]

Hey you are welcome m8,thats what friends are for,i wish i had a friend to share calterm file with me...................

[hercamp]

in the calterm thread is shared...about the ecm repairs..one common fail of celect plus ecm is the jake brake or engine brake actuator...how I ve seen ...the digital output and internal components...get some damage ...I think for engine brake electro valves...
solution of this is ...take the actuator signal and connect to relay..also the input signal its same ..with it we can be sure of ecm ....has the fuel control when active...and we can connect in two forms .
when we have one of two output signals damage ...whe take that and connect to master relay brake that we are trying to put.
other way when we have all outputsto engine brake signal damage ...in this case we can take negative signal from eng.brake botton and connect to relay..this one is alterntive to solve when we dont have ecm to replace.

I hope this help or suggest .help u and help to others to make a new alternatives ...its just how I have solved.

[electrobato]

dear guys woul you be so kind and help with a problem with a Cummins Celect Plus 3408303
I was being able to acces to the ECM, but it told me that the ECM needed to be recalibrated, so I selected autodetect calibration and suggested the right for the truck,

I follow all the steps to recalibrate, but at the end of all the operations the last 3 steps failed and the calibration did not transfer succesful.

I did all of this from the conection inside the driver cab,

after not workinf the calibration download process, I decided to to try with the connection from the engine, and looked like it was going to work , because some more new bars reload... making look good, and before I was able to turn the ignition key on...

again the transfer failed, the laptop disconnect from the ecm and now

I can not with ECM....
what can I do... the ECM is like not detected.. insite tell me to check connection but I know all cables are good...

thanks in advance for your help...
I will appreciate it a lot any help...

TAMBIEN hablo espanol.

Last Update:
Now the truck does not turn on, I'm in troubles, 'cause the first problem was too much smoke, but now, I have to make it turn on..
Any help is appreciate it a lot...

[hercamp]

is good that u speak spanish too...but forum in only in english.........
so about youre ecm yeah ...for insite youre ecm is dead...it come blank..and u cant get connection and the engine doesnt start..because ure laptop cut the connection with ecm ...and it cant happend ...I think that u can have some problems in the laptop...or maybe u choose a wrong cal for ecm ...and u most know before download the program to ecm ..sistem need delete some info and part of programing first and ..unic way to get it works its calibrating from boot mode ...best way to do is with calterm..if u know how works with it u can solve so fast ..if u dont ...just try with insite in boot offcourse ...now if u dont know how to do in boot ...sorry youre ecm is dead.

Hi
This not a train smash,just turn your key on for 5 seconds,turn it off and and connect to the ecm with the key off and start a new calibration download.
Goodluck
:coffin:

[mondao]

I have a problem with an ecm one isx cm570, engine brake does not work, the problem is that always the (ecm) detects the clutch, as if was pressured but really not this pressured. i adjustment of the switch of the clutch, switch, and circuit to resolve the problem but alone changing the ecm I am solved the problem, I ask me if a solucion exists so that this ecm be able Repairing, because already it recalibre again, and not corrected?


greetings

[hercamp]

yeah the recalibration most correct the problem,because or maybe u dont have a physical component damage,also u can connect with calterm,upload the calibration,after that disconnect to ecm and open the cal file ,and select paramters search,edit the clutch switch and dissable,this component its optional ,not al models have it and u can dissable,its how I ve done couple times.

[mondao]

ok I will try calterm

[imhsar]

you can go for service center, where did u live, just tell me your location , i will give you the service center addresses, i think they will help you easily and you can further ask any other problems...

[hercamp]

yeah .we..go to the service center....and close the thread

[dimitar22]

I don't think that going to the service center is the solution of the problem, the service center in my county is 200 km from where i leave, the point of this thread is to share solutions on how to to repair ecm by your self.

[mondao]

sorry to say but I can not do good work with (calterm)
maybe can give a different use for this (ECM) in another application,maybe generation,
if anyone has an idea, (I have little imagination) sorry mates:pcguru:

[hercamp]

calterm ...at iquals to dct ...works in all cummins ecm?s and u can do anything...something special!!! u need to upload and change parameters after that download.

[mondao]

thanks I continued trying to learn a little before sending a calibracion

[hercamp]

to download a calibration ...in a programed ecm its not so difficult just send...but for a new ecm or blank one u need to make bench cables.

[mondao]

my problem is solved now, thanks I went with a cummins dealer and a new one is
post closed

[dimitar22]

to download a calibration ...in a programed ecm its not so difficult just send...but for a new ecm or blank one u need to make bench cables.

I have original 2 pin 3 pin cables can it be done with those one?

Or i need some other cables?

[hercamp]

calterm...works with same connectors ... differences with insite ..its the bbot mode ...necesary in new ecms...and special for it are bench cables...the other funtions like read ,delete fauil codes,edit parameters and aply changes in the ecm ?s cal all possible with inline...in the 3x vercions I think its possible to with usb link,dpa4,noregon or rp1210a

[peter21]

hi guys i have a litle problem with ecm celect P/N 3618046, this ecm have the active code 351. Injector power supply below specifications inside ECM.

This code to appear together with 434 code. i found problem in power supply to ecm. I repair it, and 434 code go to inactive but 351 still active...........Does someone know as repair this?

thanks in advanced.

HI
Are you getting 100volts on the big green capacitor? If you check just behind your actuater harness you will see surface mounted transisters in between two heat sinks,they should be six in number,check that none of them have a shot circuit,if so replace and that fault code should be history.

[peter21]

hi makura thanks for answer. well i check the transisters and i found 2 bad, 1 between two heat sinks and 1 behind to the big green capacitor. I going tomorrow to buy them.

thank you soo much for answer, i tell you how working the ecm.

[peter21]

well, i install the 2 news transisters and same i still have code 351 and i can't get 100 volts in the big green capacitor.

I still checking the ecm and if I find something more that this failing i tell you guys. Makura if you could give me some suggestion, I'll gratefully to you buddy.

[hercamp]

u have the ecm connect stand alone?...or you check connect to inyectors arnnes.

[peter21]

I check connect to injector harnes.

[makura]

What's the voltage you are getting on the green cap,are you getting a noise like a scream or are you getting a ticking noise?

[peter21]

well i just have 13 volts in the 2 points on the green capacitor, and i can't listen the ticking noise.

[makura]

Ok,if you look just near your actuater harness you will see a small transformer,there are two diodes(look like surface mouted transisters)one should have 17-19volts and the other 22-27volts.if not look on the far end to the left of the actuater there is a 2901,if you look propeerly you will se a 10 ohm resister labeled 100 it is usualy open circuit or one of the two diodes has coroded,if so replace with 1n4148,just trace the circuit and solder the diodes on the reverse side of the pc board.
let me as soon as you have checked these things 90% chance you will have it running after this check.

[makura]

Oh by the way once you get it going change all the electrolytic capacitors

[colh]

Hi Fella,s
I have a QSX 475 in a Case Steiger that hunts up and down at around 1650 RPM just like an old mechanical governer that overshoots and then droops under.Even under load it is still there quite bad and this is where it is used at.Been like it since new apparently not fixed under warranty and not showing any faults.any idea,s welcome.

[DiegoAC]

yeah .we..go to the service center....and close the thread
hercamp
... hilarious!
BTW, Mondao, how did you end up fixing it?
Makura, any sw to recommend for cummins electronics schematics (I mean detailed as your posts)?
Thank you all great post.

[makura]

Recalibration will solve your hunting problem,no scematics for ecms,sorry

thank you soo much buddy, i check the diodes and i found 1 with problem , but i change the 2 diodes and all the electrolytic capacitor, and now working fine.........
:rock::thrasher:

now the green capacitor have 105 volts, and i can listen the ticking noise.

Hello members:

In some Celect and Celect Plus ECMs I had the error code 343 (microprocessor comunication error inside ECM). I tried to fix it with changing new memories (with good know files) , changing capacitors re-solder the main processor but the problem persist.

Do any of you have experience with error 343 ??

Any ideas to solve it ?

343 replace main micro procesor,or FPC(fault procesing chip)its the big plccc chip in between the main proceser and the eeproms

[elecautocr]

Hi Makura

Main processor is Motorola SC38KG018CE04, Do you have datasheet of it ? and source to buy it ?

FPC(fault procesing chip) is Intel but I don't know which is the correct part number of it, Do you know ?? again source to buy it ?

Thanks

Hi friends, I have 3 celect plus ecm with a internal short circuit (two of them was broken the last week) I supposed that this is a common failure in that kind of ecm and go to disassembly it to see if I can repair it. Anyone know if it is a commom failure ?

Thanks

[mondao]

failure in Cummins, Cummins Celect, and Celect Plus ECMs
buscando ayuda en linea me encontre estos tips talvez ayuden un poco

Corrosion and moisture:
Corrosion or damage due to moisture is one of the main reasons for ECM failure. Corrosion can enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself. This happens over a period of time (5 to 10 years) due to the ECMs exposure to the elements.
Fuel solenoid:
The electronic fuel solenoid is also a main reason for failure in the ECM. The solenoid can cause a short in the ECM due to corrosion in the solenoid or the wire running from the solenoid to the ECM harness. The electronic fuel solenoid is located at the top of the fuel pump. The solenoid seems to fail due to corrosion as fast or faster then the ECM. If your truck is running fine then you shut your engine off and it won't restart then this is a good indication that the starter has shorted out the ECM.
Injector wiring harness:
The third thing that can cause failure in the ECM is the Injector wiring harness or the sensor wiring harness. Once again corrosion or breaks in the internal wiring in the harness can cause a short in the ECM or corrosion can enter the ECM through the wiring harness. Again this is caused by exposure to the elements.
Grounding issues:
Another issue that can cause failure in the ECM is poor grounding. This can be the result of loose or corroded ground wires to the battery or the frame. This is especially problematic in the Celect Plus model.
Starters:
Replacing the starter with the wrong model starter is becoming a big problem with the Celect Plus ECMs. Many starter rebuilders will bypass the override sensor in the starter. The override sensor regulates the voltage going to the ECM so when the override sensor is bypassed you will get voltage problems in the ECM and it can generate fault codes or other problems. If you only started having problems with your ECM after installing a starter then the starter is most likely the root of your problem.
Dead battery cells:
Dead cells in batteries can cause failure in the ECM. Many times a battery is left in the rig long after a cell has died. This affects the grounding in the battery.
Jump start:
If the vehicle has been jump started recently and the cables were connected improperly this can cause a spike in your ECM and cause it to short out. A bad jump can also blow out 2 amps which are located between the ECM and the firewall.
Welding and lightning:
Arc welding on the frame can blow out the ECM as well as lightning strikes. This is not very common but it does happen from time to time.

Identifying the problem:
If your check engine light is on then you should be able to read a fault code from your ECM. The fault codes should help identify where the problem is originating from. You can also check the voltage where the wires come into the ECM harness with a voltmeter. The voltage should be between 9 to 12 volts for optimal usage. Anything 6 or below and you have a problem.

[peter21]

hi guys i have an ecm celect with code 321, i check the transistors of injectors and i found the transistor for injector number 4 with 12 volts, well i follow the circuit and i found with short cut a small diode similar to the diodes that the transformer has , i replace that for 1N4148, then i test the engine and run fine for 5 minutes, after of that time the engine shut down.
Can't to be adapted 1N4148 since do I replace of this diode?

If it is like that which I can put?

the diode are located in reverse side of pc board, near the long heat sink of the shore.

well what you will need to do is get one ecm that is burnt beyond repair and take the diode from it,or take a picture of the pcb and mark the diode location,it's hard to know which one you are talking about with out a pic.

hi buddy, well i have one ecm caterpillar 3126 burnt, and i see an similar diode there, i'll install that diode tomorrow and tell you how work. and tomorrow i put a picture to.

Thanks for answer my friend........

[peter21]

well guys i change the diode to my ecm cummins and i install diode from ecm cat 3126, the engine working very very good for 10 minutes, then the engine start to misfire and now my ecm have the code 322.... LMAO.... i don't know what to do..... Here a picture of the diode that i change.

30818

[rp1210a]

Those look like transistors you have circled. Where did u see part number 1N4148? You may already know but there are different types of diodes with different forward and reverse breakdown voltages (zener). Check the voltage at the diodes/transistors while truck is running and compare them to the other sets to see if the voltage is out of range.

EDIT :should have read full post, now see makura post with diode part#

[peter21]

well guys the ecm working nice now, hey rp1210 you have reason that's a transistor, am beginning in this of the electronics and tape-worm my doubt if it was a diode or a transistor, to the beginning i think that was a diode, and i test with 1n4148 and zener and same they were giving me always fault.

then i see to my friend makura say "what you will need to do is get one ecm that is burnt beyond repair and take the diode from it" I do that, i take the transistor from a caterpillar ecm, and the code 321 disappear, but appear code 322, well i check the circuit and the tests took me up to the hot sink, who is in the middle of the ecm, change it, and now the ecm works well, the code 322 disappear.......:thrasher::thrasher:
This way that thank you very much guys for his suggestions... especially to makura, always he help me in this of repair ecm

[ECM specialist]

please can you tell me how to recalibrtion cummins part 8303 ecm , i have one active 111 -- 1 count , how to get this think clear up....
thanks again ...

I been waiting on someone to help me . to get this ecm reprogram . active 111 on 1count , I know 6662 or 8300 work's
but 8303 don't take calibration shows faild , over and over the same/ please someone help thnks to all like allways.

[zds]

peter21, thanks. you finished my schematic

[peter21]

peter21, thanks. you finished my schematic

you're welcome my friend. I thanks you too for having done the scheme, only needed the rom boot.....:barscarf:

[zds]

peter21, I think there must be 3 separate wires from 10,12 and 14 to button 1, don`t I?

[hercamp]

just make a joint ..before turn ignition on...and separate them ...after 5 seconds ...thats all

[Poptest]

peter21, I think there must be 3 separate wires from 10,12 and 14 to button 1, don`t I?

Hello ZDS,

I copied your ROM boot cable and tried it out. I am not able to communicate or calibrate footprinted Cel+ ECM.

Have you tried this using this harness setup?

Thanks much.

[zds]

Poptest, i tried it, and it`s works
but I have spent a lot of time to connect it correctly. draw attention for marks on connectors (On the scheme they are represented not as you look at them, but in mirror image)

[Poptest]

Hello ZDS,

Your drawing shows a +12v unswitched battery connection to pins 20, 21, 22, & 23 on Actuator harness C. I only made a single connection to pin 22 because these 4 pins are internally connected inside the ECM. Could this be the cause of my problem?

Today I will connect them all like your drawing shows and try again.

Thanks again.

hello friends .. I'd like to make a ROM boot harness. for isx cm570

Can someone please share how this harness is wired?

Thanx much.

me too, please!

[peter21]

peter21, I think there must be 3 separate wires from 10,12 and 14 to button 1, don`t I?

yes ZDS you're right, there should be separate. Thank you for the observation........ now the scheme is complete.....

and the procedure for have boot in the ecm is as my friend hercamp said..... "just make a joint ..before turn ignition on...and separate them ...after 5 seconds ...thats all".

[Poptest]

peter21, I think there must be 3 separate wires from 10,12 and 14 to button 1, don`t I?

Hello ZDS,

I have these questions:


Your previous diagram showed pins 12 & 14 together, which closes to pin 10 on B connector. Should I separate all three wires?
I also see an "open disable signal" wire on pin 3 of A connector going to pin D of 6 pin connector. What is the purpose of this wire? Can I disregard this wire?

Thanks

[zds]

servando, mondao
look this. i made scheme, but it is not finished. it is without Rom Boot button. i don`t know what pins must be connected to Rom Boot
maybe hercamp helps us again and will say what pins must be connected

PS this scheme for ISM and ISX cm570. first i was wrong and made for ISM cm570, but when i was start making for ISX i observed that them are same.

1. that diagram not mine. yes, you must separate all three wires. look post #67 or 68
2. i don't know what the purpose of this wire. I connected it.

PS 6-pin connector (on scheme) is socket like in the cab, not a plug of diagnostic tool. If represent that it is diagnostic plug (e.g. of Nexiq) you should change places of E and C pins

[servando]

hello friens.......and you heve esquematic..for ecm of isx.....recovery memory rom

thanks very much

bench harness..used to calibrated any ecms stand alone

rom boot mode used to calibrate ecm that will not accept calibration in normal mode or will not communicate with service too ...special after get calibration error.

ecm that do not have rom boot mode.
ecm on engines B5.9G...C8.3G AND L10G
CELECT ECMs, centry and isb dont have rom boot too.

all that is what I had tested.and is just my experience.


I hope that help u

[thermo_1]

Hello! and thanks for sharing. I was wondering, is the purpose of the rom boot switch to connect the 3 wires or is there another connection that I just dont see? Thank you so much for your help!

We couldn't get the rom boot to work. Can you explain how to do it? It looks like the ECM connects automatically when we plug it in, no matter what you do. It doesn't reboot. Thanks if you can help.

The ROM Boot wires have to be joined (ROM Boot button depressed) when the keyswitch is turned on, then release after 5 seconds.

trying to put QSOL screen shot into post
hopefully it will be below

[hercamp]

well..I ve seen a couple isx..that stop calibration transfer and never ..get connection again
try this...

connect the ecm to calterm through manual conection
if is possible with inline (80%) succefully...or usb link
you need to try to connect with ignition off...we do that because dont have rom boot pin out ..and off connection make that...too
if you cant until all that ...you will need to connect by j1939 ...triangle conector ..if your ecm is not burned..that will works 100%..and try to get connection
after that you can download calibration to the ecm.

is just my experience.

[jctech]

When you recalibrate an ECM, especially on J1939 datalink, you need to remove as much other datalink traffic as possible.
All the messages on the datalink have a priority, ABS and throttle usually have the highest priority, then dashboard, transmission and all the other modules using the datalink.
Insite has the lowest priority of all, because it must not interfere with the operation of the vehicle if used on a road test.
These modules are broadcasting as soon as they are powered up even if truck is not moving or the engine is not running.
Then we connect into the datalink and expect to be able to load a 2MB calibration into the ECM down that same busy datalink, at a lower priority than all the other data.........
Cummins recommends disconnecting as many other modules as possible when carrying out ECM recalibrations, to remove as much traffic from the datalink as possible, and for Celect plus, connecting to the service datalink on the side of the engine, not the public datalink in the vehicle cab.

The problem with this engine is when it warms to the normal engine temps, idle speed goes to 900 rpm. I don't know engine cpl, because it was repaired with different cpl parts. I tried 1844 cpl with a 3084473 ecm, it works fine, but it has a 3619037 ecm, any ideas?

You have the same question in the calterm thread, see the answer there

[joe gp]

hi guys

busy with engine simulation on Celects and Celct Plus on the bench.....been playing for a while now with signal generators and output-ing the signal thro a headphone jack on the EPS attached to my harness.....haven't had the best of luck so far......any ideas would be highly appreciated........

[jctech]

get hold of a camshaft gear, and spin it with a motor to give the ecm a speed and position signal.
You will need injector solenoids, all sensors need to be connected, but only oil pressure sensor needs its status to change to show oil pressure with the engine running

[Trucke]

Hello all Interesting thread going here. When calibrating it is best to use the dedicated data link in the engine harnes with the triangle deutch conector at the left front of the engine. Cummins makes an adapter cable to fit this. It fits on cummins inline adapters. It has the 3 pin plug and a power cord that plugs into a cigarete lighter plug. If you or your shop has an old echeck kit still around it may be with it. When I get some time I want to make an adapter to use this system with the nexiq usb link. Maybe sombody out there already made one and is using it? If you do have the Echeck kit and the diagnostics 2.0 cartridge blow the dust of it and you can read sids, mids and pids from almost any brand of engine with a 1708 datalink.Get some fault code lists printed out and your good to go. Great for monitering engine sensor outputs during road testing to no battery to die half way through. They also made a Echeck cartridge that fits the prolink might as well use them if you have them.
Great work on the dk forums guys Thanks lot of great info.

hi all I am new to all this but find Iam going to learn alot here. Gr8 thread you have here. dies anyone have schematic for serial cable that joins inline 5 adapter to pc comm port. Many thanks in advance:congrats:

[hercamp]

the triangle adapter is for connect inline in j1939 and nexiq cant ..I did one with resistance but not stable connection and only possible with inline to safe mode ...and about squematic ...calu78 posted time ago a manual of dpa4 plus ..well is same db15 and usb,deutch conection than nexiq....see in the thread about squematic most be there.

hercamp, how'd you do it? I made a j1939 cable for the bench, for usb link, it works fine, I used a 120 ohm between the data lines, I'll try to post the schematic this week if you want it.

[hercamp]

I mean not good because after to load and download all blocks with usb link connection makes to burn a diode into usb link .works for a time but .I think for high baud and bits in the transfer ...resistance in the backbone works cool also if they are at 60 ohms but is just my experience...is safe and better to get same connection in j1708 also with faster transfer with usb link ...the j1939..Ive used only with ecm that needs bench and rom boot mode.


and thanks to my friend carlu78 that upload this ..dpa /same pinout of usb link.enjoy

[hercamp]

to all..fiends that have ...an isc ecm and e2m doesnt match with the stores...post ecm part number/cal vercion and we can get an e2m to that vercion.

[alsop]

I'll post the power adapter harness as soon as I finish the diagram.

[alsop]

This is the universal power harness. Post 62 showes a scanned picture of the assembly with a 6 pin Deutsch cab interface connector, before J1939 was used. When I get the time I'll post another Rom Boot parent cable assembly for another engine family.

Hi all.
Have been following this thread closely but have not found a sure solution for repair of fault code 111 in celect plus ecm. Others suggested replacing at28c64 memory but then there was a question of reprogramming the chip. Has anyone successfully repaired this or are we still battling for a solution?

[hercamp]

I have seen 4 or 5 ecm with 111 code...4 of them .that I just program with calterm in rom boot mode ...the other cant and I just blank memory and program in rom boot too with insite.

just desconnect power and connect after 3 or 4 minutes and turn ignition on...and off after that try to connect with calterm..if the connection is stabliced just download a calibration ...this can save your ecm.

[justme84]

I just bought a truck with an ISX cm871 in it, i suspect some of the numbers have been played with, the ecm shows 75,000km but has 14,000 hrs and the odometer shows 300,000km, just wondering if its acutally possible for someone to have changed the mileage in the ecm for whatever reason.

Is it the original ECM from the engine?
The external dataplate should show the engine serial number and calibration data if it is.
There will be a sticker on the rear with this info and a manafacturing data as well.
If the ECM has an "RX, PX or NX" part number tag on it, then the ECM is a replacement.
If the ECM has no tags or dataplate then I would suspect a used replacement has been fitted.

The mileage in the ECM can be altered, using Calterm, but it is not easy.

hi all.
Well didn't know where else to post this so this thread seemed to be most relevant since it involves ecm repairs I need help identifying the cpl for this motor it is an M-11 celect plus and its engine serial is 34810648. The dataplate has been removed off the engine and I am trying to solve hardstart and high idling issues. The hardstarting I have managed to rectify by replacing the fuel pump now trying to remedy the high idling and also had forgotten to mention that the engine will continue to run long after the ignition is switched off. Have come across this before and it was a result of wrong cpl ecm on truck. Would also be grateful if you could state correct injector part number for this particular motor. Many thanks in advance to all my DK brothers and sisters.

Thanks again m8 for all your help. After connecting ecm to insite cpl is stated as 2036 and all calibration files i have gone thru in a c94 file state that 2037 cpl is rated at M11-400E plus. Where do I find the user fueling state you speak of?

[jctech]

Connect Insite to the ECM, go to datalogger monitor, select some parameters for example
engine speed
percent throttle
coolant temperature
oil pressure
user fueling state

start and run the engine
at idle, percent throttle should be "0"
user fueling state should be "LSG"

Try disconnecting the return fuel pipe, before the check valve, and run into a container, if this cure your issue, fit the check valve into the line, still into a container and recheck, work your way back to the tank.

cummins insite /calibration data dont works like that...you need put an incal disck ...non expired..(just works for 6 months) and connect to ecm ...wait for insite aprobal and see the calibration listed....choose one and download to ecm...after that insite will ask for fleet calibration code/ or fleet calibration acount .
after that you can download the calibration to ecm.

thanks hercamp for your input. Have managed however to use files sent to me by hpcummins in an earlier post this way which were for an april 2010 calibration of eci the celect calibration file. Just want to try out with the other files so that i can post my findings for everyone to share without having to download entire cd for incal. To use these files hpcummins said that he had to change the date back on his computer whilst in insite then calibrate his ecm but I have also managed to alter the date on this file and it now reads as March 2011. So it is possible to use calibrations after the 6 month expiry. If some1 has the files I asked for please post so I can also post my findings. Thanks DK bros you guys rock.

about egr ..is normal get fault..if the diesel fuel is not too good or the time of change for fuel filters is too long...try to clean and realibrate with insite...make a couple test..maybe is not damage yet.

[je69]

hi everybody, about the isx egr and fan,yes hercamp i got new fuel fllter,diesel its new,iclean the valve and the litle electric motor its good, when you sain recalibrate you mine recabrate the valve with insite or recalibrate the ecm, thanks

[je69]

also i clean egr sensor they was dirty you now carbo but now the rpm come down to 800 theywas 950

[makura]

well all you need is any incal cd go to my computer,explore the cd,open the file intelect,then open esdn,then open data,copy the folder you need and past it in C:/calterm it will ask if you want to overwrite the existing file click yes to all,now when you want to calibrate using calterm,you will have to choose the cal file from C:/calterm,go to the folder of the type of ecm you want to calibrate for example lets say select plus,you nevigate to the folder c94,open it and select the cal file you want.i have gone through all my celect plus cal files in calterm and renamed them,using CPL,HP,TORQUE and RPM/gorvnd speed.
This makes it a whole lot easier to select a cal file if you don't know the ecm code by number.
After you select your file you can now calibrate your ecm using calterm and files from an expired incal :listen:

Even when you are not getting around 102 volts on large green capacitor you should at least get 12 volts on it when the injector boost voltage circuitry is faulty. Are you getting 12 volts on the 2 legs of the silver diode when ecm has battery supplied and ignition turned on.The diode looks like a power transistor.

Hi friends.

I have a problem with a Celect+ ECM. I tried to recalibrate with insite, then calibration fault, after, I removed the ECM from the engine and connected it stand alone, I put the start switch for 5 seconds and it start in ROM mode. Afther, I start a new calibration, but always fails in 80%.

Some idea? I have calterm, but I have no calibrations for the ECM. :viking::help:

Some idea? I have calterm, but I have no calibrations for the ECM. :viking::help:

How did you calibrate it with insite if you have no calibration files for that ecm? And secondly why are you performing a recalibration? Also you did not give feedback on what you found with the celect ecm you were working on. The idea of these forums is to share problems and solutions. Feedback please, its important for others following the thread to know whats happening.:hello:

[sptecnico82]

OK. I was no more working with the celect, them I dont have any feedback yet. I calibrate the celect plus with incal cd.

[donniemnemonic]

had also asked you why you wanted to recalibrate the ecm? is it to change engine parameters or does the ecm have a fault requiring recalibration? e.g footprinted or seeded?

[sptecnico82]

The ecm was from a M11 and need to be used in a N14, many parameters dont work properly.

[SaMirakle]

That's going to be something internal then. I work on these ECMs everyday. I'm assuming the common 5V to all the sensor pins are missing or am I wrong? There are more than one pin that need 5V for the sensors.

If it is something internal you will have to either replace the ECM or have it repaired (which I can do but I am located in the US. I don't know where you are located)

Found the module faulty and got a new one but it was not responding
does it require any calibration or any other
this is along with cm700 and ssm 558 on the engine harness

[gentechie]

to download a calibration ...in a programed ecm its not so difficult just send...but for a new ecm or blank one u need to make bench cables.
i am just searching for schematic of CENSE bench calibration for QSK60G and could not see ur post first unfortunate
but in fact i would be more grateful if can send me diagram to make a bench calib cable for 3098771 on QSK60G or any suggestions to calibrate it
ur early response to this is very much appreciable

Hi all.
Can this procedure be achieved whilst connected to the oem harness of a celect plus ecm or do you connect to ecm using the sensor harness? Secondly when you try to connect to the ecm with the key off will the j1708 or j1939 LED on the inline adapter be flashing? Been trying to rom boot a celect plus ecm that went dead with a failed calibration attempt and now will not communicate with insite. Tried the rom boot cable but still no luck with it.

HI
Firstly you connect vie the sensor harness,and secondly the lights on the inline will not flush up until you start the connection,when connection has been initialised the flaashing is not continuas but will flush according to the data flow from computer to ecm,and this will work if an ecm fails calibration and fails to connect to the computer after the failure to calibrate.

Has anyone seen this type of ECM? Brand is Eneserve. This is installed on a QST30 genset with less than 100 hours. I can't get it to run as the ECM has no Cummins part number, and I don't have a wiring diagram.

I hope someone can share some info on this ECM.

Many thanks......

Is the QST30 the old type without electric fuel lift pump (has hand priming pumps)
Is it a CPG genset or "G drive" engine (will not have a PCC panel)

Is that ECM wired to the fuel pump actuators

You are correct. It does not have both an electric lift pump and a PCC panel. The system uses the feed pumps on the Bosch pumps. The ECM is wired to the Bosch actuators.

I replaced the Eneserve control with a Cummins ECM and harness, then programed with Inpower8. Engine runs fine.

However, i have to work on other identical engines, and can save a lot if the original Enerserve ECMs can be used.

Calibrations for ECM's are not backwards compatible, the best you could do would be to try to find a cal that is close with the correct ECM part number.

Thanks......Those part numbers are not inter-change-able,you can not use that part number ecm to replace your dead one,if you try to calibrate it using the the wrong part number you will kill the other one by doing that.
Inside these units you have two memory chips 27pc256....these are write once,this is were your base software has been written and you can not change whats written in them.so your part number tyells you the range it can go,mostly part num 361.....would be lets say in the range of cpl 13...up to 16.... and part num 308......from cpl 16..... to 19..... then comes the celect plus that you can caliubrate using different part number for cpl's 20....these donot have write once chips.hope this helps clarify you problem.

I would suspect the Eneserve ECM is a local replacement for the original Cummins FCG ECM which is obsolete.
There is a Cummins service topic describing the repair procedure for a failed FCG ECM, service topic number 03T19-20 (fit GCS module 4067777, sensors and harness), however like you say, its a lot cheaper to find a local solution.

[jctech]

The later (GCS 4067777) QST30 with PCC3201 had the "ECM" built into the PCC panel in the form of 4 "boards", that correspond to the 4 connectors on a GCS controller, These were CPG gensets only.
I have no experience of the earlier (FCG, no electric lift pump ) QST30 and PCC3201.

You are right. I used the 4067777 ECM, plus harnesses and necessary sensors. Gensets run great at all load conditions. I've actually completed two gensets, and I'll be doing another ten units.

A lot of money can be saved if the original Eneserve ECMs can be properly wired up.

By the way, each genset has a synchronizing panel, and the Eneserve ECM was wired to this panel which have all been taken out. ECM and sync panel are both Eneserve with Japanese plates.

PCC is the name for the Cummins Power Generation genset control panel, this panel controls all the engine and genset operation, model 3201 was the first to control electronic engines.
CPG is Cummins Power Generation, make genuine Cummins gensets, all the rest are OEM's
FCG is Fuel Control Governer, the first QST30 generator engine control system, the ECM's for this are obsolete and there are no calibrations on the InCal DVD for these engines.

Hi Jctech......

Here are two serial numbers, 37187076 CPL2276 and 37218459 CPL2949.

The CPL2949 engines have the Eneserve ECMs installed on them. I replaced the Eneserves with 4067777 ECM on two engines, and programmed them with Inpower conforming to CPL2949. Engines run well but have insufficient power....can hit 600kw only at 60hz. Inpower doesn't show an alternate 2949 calibration which will uprate the engine to 800kw.

So I am now thinking of uprating them to CPL2276. Do you think this is possible? Problem is.....many parts are not identical, including the injection pumps.

Thanks much for your advice.

ESN 37187076 was built in 1999, with the now obsolete FCG (CM552) ECM (part number 3094141). It is a G2 engine.
The fuel pumps on these engines were Bosch RP39

ESN 37218459 was built in 2005, (760 HP @1800) with the GCS ECM 4067777. (1340 HP is 1000kW) It is a G1 engine.
The fuel pumps fitted to this engine are Bosch P7100, and are only be used with G1 and G2 engine ratings, higher ratings use P8500 fuel pumps with light load advance for white smoke control.

Try the G2 rating with CPL 2968, it is an EPA/CARB certified rating, and has the same number of flywheel ring gear teeth.
It is 1200 HP @1800

[Poptest]

Thank you for suggesting CPL 2968. I will try this out as soon as the 4067777 ECMs arrive.

I've also been thinking of Calterm but have zero experience on this software. Have you tried modifying calibrations with Calterm?

Was wondering has anyone come across a similar fault in celect ecm where fault code 255 is active but when substituted for another the code does not come up.after swapping units it has led me to believe that the fault is in the ecm internals. Any ideas as to which components may have failed here?

Yes I have, and 255 is common. Truck driver and/or mechanic sometimes puts a jumper wire between Bat+ and pin 16 of actuator harness.

I've never tried repairing ECMs though. I replace any faulty ECM outright. That's why I'd like to learn.

Hi folks, anyone knows if there is some kind of cross reference guide for calibrations, I mean, with a given ECM code you can look at the cpl, hp, torque, etc, it would be useful for looking at calibrations without going into Insite. Thanks everyone !:beer:

sorry m8 have manged to take a photo of ecm pcb but now I need to edit it so as to identify the transistor I mentioned.

Hello Donnie,

I am quite familiar with electronics, but have never attempted to repair/replace any internal ECM parts.

I also realize that the ECM you repaired may already be installed and running on the truck. If this is the case, I don't think you should go into the hassle of dismounting the ECM to take pictures.

Thank you anyway. Your post has been an eye opener to me. I will try to repair an ECM. We have lots floating around here from previous jobs.

Hi m8.
Do you have a 100 plus volts on the large green capacitor just below the round black inductor housing on your driver pcb? Also check the miniature transformer on the same board should have 12v on some pins and 5v on the other pins. I am assuming that your ecm is unable to communicate with insite or similar otherwise then it would be working okay.

Hi guys, I have a problem.

When I did programing a celect plus ecm, the task fail, then every time I try, Insite shows afther a long time waiting and some messages about preparing the ECM error 27508.

I was using the Boot mode, its the only way the computer can see the ECM, I also try with calterm and fails too.

Any idea? :stupido2:

Which interface are you using? Are you trying to flash the ecm mounted on the truck?

[sptecnico82]

I am using a bench.

[Juanincho]

I am using a bench.

In that case I guess the ecm could have some internal damage at the memories or microcontrollers, did it have any fault codes before you flashed it the first time?

[joe gp]

heres a problem that i have quite often...celect plus em's that only show 12v on the outside leg of the green cap and was wondering if anyone could type the steps to trouble shooting this problem?

[joe gp]

the other issue is my injector supply voltage on supply pins throwing out readings like 8v??

The most common problem is a 1.8ohm resistor just near the green cap open circuit.

Nothing about memory... just common errors from the engine. :(

tx makura.....definitely check that out

are you diag lamps initialising on startup?

[joe gp]

Hi m8.
Do you have a 100 plus volts on the large green capacitor just below the round black inductor housing on your driver pcb? Also check the miniature transformer on the same board should have 12v on some pins and 5v on the other pins. I am assuming that your ecm is unable to communicate with insite or similar otherwise then it would be working okay.


if still after donnies advice there is still the same problem :
1. check your sensors if 5v is present
2. replace electrolytic cap on data-board (alot of guys forget this one)
3. check for broken or damaged ribbon cable.


hope this helped

Yes, the diag lamps does initializes.

hi all
i have a ecm with a red engine oil light on . and it has frozen .shows up on insite but can not do any thing.fitted a other ecm truck fine. so the fault in ecm.
thank for any help

sounds like the engine warning lamp.......by frozen do you mean you can connect to the ecm on the truck but cannot acces parameters and fault codes etc??

at this point i'd try re-programming my eeproms and changing ram...

hope this helps

[joe gp]

Yes I have, and 255 is common. Truck driver and/or mechanic sometimes puts a jumper wire between Bat+ and pin 16 of actuator harness.

I've never tried repairing ECMs though. I replace any faulty ECM outright. That's why I'd like to learn.


they do this to eliminate the fuel solenoid feed directly from the ecm...only problem here is the solenoid stays open...

the part number of that bipolar transistor if posted would help alot :)

[joe gp]

Yes, if you tell me what the voltage regulator is
For example:
78x05 x = letter
or LM317
and so on

got a celect plus 3096662 ecm that cannot accelerate....only idle...one of the two fault codes is 551, check my supply 4.89V and ground is good.....any help would be appreciated

Fault code 551 indicates a problem on the idle validation switch. See troubleshooting procedures is Insite.

with all due respect poptest........was hoping to get some info on the pcb level repair on fault finding....my fault chart also indicated idle validation switch....if you look closer you will see that the idle validation is dependent on the throttle switch signal and thats where the root fault will lie....

on the data board if throttle supply is 5ve and return is good ground then signal return traces through to microprocessor, signal is the processed to your idle validation based on throttle signal return....

@repair guys : if my throttle is at 4.89V will that generate my faults??

[joe gp]

The most common problem is a 1.8ohm resistor just near the green cap open circuit.


feedback on this issue: Makura cap voltage hasn't changed.

any other suggestions would be highly appreciated

Hi m8
Also check the two large transistors on the silver heatsink near the 1.8 ohm resistor Makura mentioned. You probably have 1 that is shorting.
Hope this helps.

Hi m8.
I am assuming that you have replaced your ecm on the truck in question and verified that your ecm is indeed the culprit. If so try hooking up the ecm whilst on the truck to insite and check its response in data monitor mode and post your results. Check idle validation and throttle postion signals. This is one way to verify that ecm can see these signals.
Hope this helps. By the way what is the other fault code?

hello friends

here is that the date will unlock the PC, without blocking the insite

enjoy ??????


thanks and pm for password



firstly pls upload in insite thread, lets keep this thread on topics relating to ecm repair only.
corrupt file, pls re-upload
