Land Rover Defender TD5 ECU repair

[georgedigital]

Hi everybody!
In a Land Rover Defender TD5 with MSB101171 ECU after a short circuit in the fuse box some of the tracks on the black connector were destroyed.I have not a schematic for this ecu and no pinout diagram to repair...
Does anyone have the pinout for black connector?

[Meat-Head]

Its fcuked, you need a new one.

got verdis gris init, get used from junkyard and swap eeprom

[georgedigital]

i have checked everything is ok only some tracks from power connector have destroyed.I am trying to repair it and if not i will be looking for another one though it is hard to find

[Meat-Head]

Must be thosands on eBay all nicked ones

[mike870]

It is easy to do immo off , or you can swap the eeprom , replace the unit !

[georgedigital]

i'm trying to find MSB101171 i dont know if other MSB.... is compatible

[georgedigital]

did you know for 1999 defender 2.5 td5 compatible ecus?

[georgedigital]

I have find MSB101191.Did anyone knows if is compatible with MSB101171?

[tango]

most msb modules will work unless it came off an automatic then the answer is no
replace the flash and eeprom if you want it to be exact


ROVER MSB1011171 1999 defender 44pin A0016 LDMAN41 A0015 0541
ROVER MSB101170 A0016 LTMAN41

ROVER MSB101340 AUTO discovery LT AUTO4145

[georgedigital]

Finally find MSB101191 swap the eeprom and car starts ok...After the car warm up trying to start and dont start...Take off same ecu from other car swap eeprom and same...What happened?I've started to go crazy...

[tango]

sounds like immo problem
you would have best to change flash and eprom from broken ecu to new ecu

the plcc44's are otp so you have to remove and replace

[georgedigital]

Thanks tango i will do...I don't know if is easy to do immo off.I have try it with no success

[tango]

immo off is easy post eeprom dump
but you need to replace the plcc44 with the one from broken ecu has it is different software
and then put the broken ecu's eeprom on new ecu and test
do you have diagnostics for td5 ie rovacom or nanocom?

[georgedigital]

Here the dump of eeprom.I haven't a diagnostic tool for land rover.I have autocom

[tango]

cut pin 34 on black plug

[georgedigital]

must cut and black cable with orange stripe from alarm box and ground?

[tango]

only if just cutting pin 34 dont work

[georgedigital]

OK. Thanks tango i will do and report...

The MSB101191 is from a Discovery Automatic.
The issue is it will be in limp mode due to it being an auto ecu fitted into a manual.
Also the temperature gauge will work the wrong way round due to the different ways the Defender and Discovery temperature gauges work.
You may also experience a bit of a jump right at the bottom end of the rpm range taking off when you are coming off the throttle. This again is due to the way the throttle is setup on the discovery compared to the defender.
So which MSB ECUS can you use?
There were 4 different ones used on the Defender.
These are:
MSB000080
MSB101170
MSB101171
MSB101360
All of these are correctly configured for the defender.
You can also use some of the later flashable NNN ecu range, however they need to be flashed with the correct software for the earlier EU2 (1998 - 2001) engine in Defender configuration.
These are:
NNN000120
NNN500020
The EU2 software is readily available and I can supply you with it if you like.
The immobiliser can be synchronised to the new ECU using a Nanocom or Hawkeye diagnostic system or the ECU can have the immobiliser removed.
I can also make you an emulator that you can solder in and forget about if you can get me a dump of the original eeprom as a worst case scenario.
Regards.

yes sorry never noticed :( my bad
its been along time since i messed with landrover ecu's (2005)

[georgedigital]

If i swap eeprom and flash from MSB101171 to MSB101191 will it work?

[PsiDOC]

In theory it should however I have varying results.
Sometimes it works.
Sometimes not.

[tango]

off top of my head i think the auto ecu's have extra components inside
its not that hard to remove the plcc44 and the eeprom to try tbh
worth a try otherwise get another msb ecu

[georgedigital]

I change eprom and flash and car don't start no mil nothing...

Correct there's a Can Bus chip in the right hand corner by the connector.
If it's not enabled in software it's not used.

[PsiDOC]

OK back to basics then.
When you key on, does the fuel pump run? If not the ecu is not booting up and you may want to check your soldering.
If the fule pump is running, can you talk to the ecu with diagnostics? If so what is it saying on the fault codes?
Ideally we need something like a nanocom so the security status can be checked and see if the ecu is synchronised ot the AS10 unit or has the immobiliser removed.

[georgedigital]

The power supply of eprom and flash is correct (+5v)I have no mil no power on fuel pump relay no communication with ecu using flash and eprom from both ecus.Original without immo off.I think the problem is on micro or a bad contact on board while warmed to desolder the flash...

[georgedigital]

did someone have correct pinout to test msb ecu on bench?

Yes it sounds like it is dead in the water. :(


did someone have correct pinout to test msb ecu on bench?

Ground (0v) : Pins 1, 2, 24, 25
Ignition on signal (12v): Pin 33
Power (12v)from main relay: Pins 3, 22, 27
Main relay on from ecu (0v switch): Pin 21
K-Line for diagnostics: Pin 18

[georgedigital]

The same on the bench...I checked pin to pin everything on board and its ok.The power ok and the ecu is dead in the water as PsiDOC say...

Oh no.. :(
Ok backtrack your steps. A non boot condition can happen if either the 8pin eeprom or the 44 pin eeprom has a bad solder joint.
If that's all you have done have a good look in those areas.

[georgedigital]

I think it's not so easy my friend.By the way i will check.Thank u!

[tango]

are you sure you soldered the plcc and eeprom the correct way ?
easy to put pin 1 in wrong place

[PsiDOC]

I think it's not so easy my friend.By the way i will check.Thank u!

Anytime. If you're prepared to work with it I am still here to help. :)

For your reference, Attached is the correct orientation of the 27C1024 eprom.
As Tango says, it's easy to get it 90 or 180 degrees out.
As you can see the flat corner of the eprom used for orientation goes closest to the processor and towards the edge of the ecu.
HTH.
Si

[georgedigital]

i do it right and i checked many times.After all i have 2 ecus to compare...and for confirmation i attach a foto

[tango]

recheck this area it dosnt look right

[georgedigital]

to the 8pin eeprom in this area is 5 and 8 pin with 5vdc and its ok pin 6,7 not connected.To 44plcc i have check all pins one by one.I will put a socket so i can put and take out the flash and experiment.I think that is software problem

[tango]

software as in the flash on the plcc44 ?
if so how? you have 2 plcc44's one with 171 sw and other 191sw these i cant see getting corupt
the plc44's are OTP
are you in the uk ? if so what area ?

[georgedigital]

I can't find another explanation. The problem started when I tried immo off.I try each flash with the corresponding eeprom with original file and the ecu does not boot.I've checked all the joints and it's ok.I read the flashes and eeproms regularly. I haven't burned them since warming up.What else can it be to blame?Is the processor?

[georgedigital]

i can't read mc68336.Galleto can read mems3 only NNN ecus with 29f400

[tango]

the only eeprom you need to use is the original eeprom from the original ecu for the defender you are try it on
the eeprom from new ecu you should put to one side and leave it there

[tango]

i can't read mc68336.Galleto can read mems3 only NNN ecus with 29f400

29f400BT and some have 29f800BT is just the flash is flashable unlike on the older mems3 is OTP plcc44 27c1024

[georgedigital]

ok.Thank u Tango i think must find other ecu

[tango]

just make sure you have the correct eeprom for the car (it not only holds the immo, it also has the injector codes in it)

[georgedigital]

Solved!!!Programmed new flash from backup and the ecu is alive again!

[tango]

you mean eeprom backup ? because flash has said above cant be reprogrammed because the 27c1024 is OTP

[georgedigital]

i mean that programmed a new 27c1024

Hi mates,
I was looking for someone who repair this kind of ecus and I found one from portugal on ebay:
CARPOWERCHIPS (LUIS PROENCA)
RUA FERNANDO DE ALMEIDA N24 -
2790 488 CARNAXIDE
PORTUGAL
+35 1919792574
info@carpowerchips.com

He picked my unit up and after 2 months he block my number and I cant contact with him. He has stolen my unit and my money.
anyone know this scammer?
I'm thinking of reporting it to the police.
I hate scam people. Be very careful not to fool anyone else. On eBay you have positive votes for purchases but not for sales.
If anyone can help me find this thief I would appreciate it.

Thanks a lot

[Meat-Head]

Is it too far to go visit him? Take some ‘friends’ with you

[alclot]

He is not in my country but I know a lot of profesional people on Portugal and I´m asking about him. I hope soon get this person.
Please careful with this kind of people. More than 10 years working for people and never try to cheat someone. I hate that!!!!

[Meat-Head]

Get and old ecu, fill it with dung and post it to him

[alclot]

This thief must have sold it to someone else. I imagine if I were a private customer without the possibility of obtaining a unit. He has stolen it and the money. If I could not find another unit, I would have to take the car to the scrapyard. Disgusting that there are professionals like that.

Your file with immoOFF...

Don't forget to cut pin 34 on black connector...

Hi all,

For this ECU, someone knows the amp value of fuses inside PCB?

I retired this picture from internet, because has the fuses marked.

Thank you.

Rezistor 1302 Om

[swisstuner]

Guys Ive gotten myself into a bit of a pickle here. I have a car with NNN500020 ECU. Its a 1999 Defender 110 Td5 120 PS Manual. The ECU just stopped working, we dont know why. When we connect it up the fuel pump works, but it will not start.
Purchased a replacement MSB000080 and found its not programmable.. too bad.
When simply installing in vehicle it runs, but of course check engine light is on with a multitude of codes.
Attempted KESS connection (hence found out its not programmable). Therefore no way to right original KESS data to the flash of the replacement ECU.
Attempted to solder old ECU EEPROM onto MSB000080 ECU without result (the ATMEL AT93C66) . Car wouldnt start, does not activate fuel pump.
Resoldered AT93C66 back to NNN500020 ECU - pump works but still no start.
Resoldered ATMEL AT24C01 EEPROM back to MSB000080. Now the car does not start. It does not activate the fuel pump either.
Tried flipping it around in case I screwed up - no luck.

Not sure what to do from here. Seems I got two useless ECUs? Any advise and help greatly appreciated.

are you sure? But both components marked in the image are 1302 resistors?

I have the msb000080 ecu from my defender td5
I try to set it immo off but I made a mistake Iread the 93c46 as 93c66 and modifi this file and write it back
the errase go wel but the program not nou my 93c46 is blank and i don't have a backup
What can i do
I hope you can help me
Best regards Chris

hi, i see i'm late to this party.

did you get sorted or is the knackered ECU still sat somewhere waiting for help if so i should have an example dump i can send you to get you going.
