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

yeah ...its works ...fine ...in retreivering of parameters also ..I cant save one but the others two ecm works ok.thanks
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.
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...
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.
any ecu programming tool or any device to check ecu problem avaible in market please to informe me , all ecu schemastic
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?
