Hi
In this video I will take you through the process of reset, (also known as Tech2 reset), and reprogramming of the engine ECU on a Vauxhall Astra H 2004.
You can follow the second part of this steps, if for example, you are replacing the engine ECU with a second hand one, or even with a new ECU, although in this last case you might need to program the calibration software.
Hope you enjoy the video.
Any questions or comments please put them below.
Like always, thank you for watching!

Hi
Thank you for watching!
I have already answered that question a few times...
You don't, I have just done for educational purposes.
Reset it is also good if you want to sell it for example...
thank you sir

No worries...
LM Auto Repairs my zafira got problem with thermostat last summer then same day my ac compressor stopped, i suspect ac pressure sensor any help of yours wil be appreciated. The mechanic did not check the sensor he just looked at the compressor it did not start so he said it must be change but i doubt.i think the computer shut the compressor

Hi
You need to carry some tests.. or with a scanner, look at some live data, see exactly what is going on... I can't help you much further without more details...
Thank you for watching!
Brilliant, got the Opcom with no instruction on how to use it. This guide was perfect, saved me lots of money getting someone to change the ECU for me and the satisfaction of doing it myself. Best youtube guide ever. Many many thanks.
That's great!
A lot of things in life comes with no instructions...😋
Glad you got there in the end!
Thank you for watching and for the feedback!

Dziekuje bardzo mi to pomogło. Co około 2 lata sterownik gazu psuje ecu i musze to robić a nigdy tego nie pamiętam jak to się robi Pozdrawiam z polski
Great video on this subject. and clear instructions of how to use OpCom
would be nice to see how you reset the controller ECU in the boot of the Astra H Twin top 2009
Looks decent, the only thing missing is instruction how you obtain a security code. Love Your videos, cheers.

Ah, and for the feedback!
Good to know that my videos are helping people...
@@LMAutoRepairs How can I just turn it off check engine light?I have the same diagnosis.
Thank you for sharing your knowledge with ignorant people in this field.
I wonder if I can get your opinion also...
Astra H 1.9 cdti engine light appeared one day and car went very slow. I checked codes and we're related with egr valve. Took it off, cleaned it, placed it back on (didn't connect the plug for educational purpose). Engine started normally and died after 2 seconds. It never started again plugged in or off. Cranking sounded different, much weaker like if an electronic device was preventing it to work properly. Found a similar problem online which was resolved by switching off the battery for 30 min. After doing the same, engine never cranked again. Spanner light is on and fuel pump relay is clicking like crazy with fuel pump doing some noise too. If egr plug is disconnected, the relay is quiet and also the pump but nothing happens either. Tried other relays, same situation.
I've got the op com now. Maybe the immobilizer is on?
Thank you
v.m3
Ok
You have opcom, codes?
Check immobilizer live data and report...
Thank you for watching!
LM Auto Repairs
Sorry, to which op com codes do you refer?
If you mean the car pass codes, I do possess them.
I'll see what the op com shows and let you know ;)
Thank you for your prompt repay.
v.m3
Yes, fault codes... also check the live data for the immobilizer...
Good to see how easy it is to put another already ecu in. My question is this.. do you not need to change the vin number and do the aircon, cruise etc?
you need the pass card in the owners manual thatll have the numbers you need to match the new ecu and also if you have cruise control youll need a ecu from a car that has cruise
What is the software your using please
They are using an opcom interface. You can find it on aliexpress. It comes with a CD.
Very helpful,, bought a cheap none runner (dead ecu) got cheap reset ecu off ebay, paired as said 8n the video and job done :) cheers guys

Hi, enjoyed the easy to follow clip. Thankyou.
Issue: I have a Corsa VXR and need to replace the existing ECU which has been remapped and have it replaced with a non remapped donor Corsa VXR ECU. The reason being is that the car failed an MOT on emissions with the remapped ECU so, i have been advised by a few mechanics that the lambda and catalytic converter are all in working order and that the easiest way to try and resolved the emissions issue is to install a donor non remapped ECU.
Question: Can the one car key be programmed to operate both the remapped and standard ECU (to allow alternating between ECU's) or does each ECU require individual key transponder programming? I guess what i am asking is can i swap ECU's as a plug and play after programming and use the one car key?
Tristan T
Hi
You should be able to use the existent keys... and have two programmed ECUs which you can swap over when you need...
Hope that clarifies your doubts...
Thank you for watching!
My customers car. Turn ignition and on crank blower relay in under hood electrical centre clicks. No crank from starter. Wonder how the wires cross to do that.

Thank you for watching!
Very nice video. Like the rest of yours.
You have done enormous amount of work, with all these videos. We are obliged to you sir.
I start studying your videos. It is a real school.
I also saw the other video, about how to program the CAN and Variant configuration.
But I wonder. Is it enough? Should we look also in the:
1. Program High Speed CAN Bus Configuration
2. Program Mid Speed CAN Bus Configuration
3. Program Low Speed CAN Bus Configuration
And what about Steering input sensitivity?
What do you think?
Peete Kastanis
You absolutely correct...
Although all the things you have mentioned are more crucial in cars with more stuff installed.
In this case, the car was quite basic, without any extras...
But yes, you should take note of all the configurations so you can then match them afterwards...
Well spotted, thank you for watching my videos and with that support the channel!
Hi Thanks for the video which worked like a dream on a Vauxhall Astra H. im just wondering is the procedure same to program vauxhall zafira 1.9tdi 2007 model.
After re allignment to the car, will the pincode of the new ecu be adjusted / relearned to the one of the car or will you always need the pincode from the donor vehicle for future resets and security access if needed
No
Once you program the module with the pin of the car, the old pin no longer needed...
Thank you for watching and for your comment!
@@LMAutoRepairs Thank you so much for you answer, Will order a used ECU then and retrieve donor ecu pin with Carprog to reset and reprogram on the current car. You are a true help my friend.

Was a pleasure to help...
👍
@@LMAutoRepairs One little question if I may ask. These MT35SE ecu's of Astra H (Z16XEP) have item number like 12230740 and then an extra coding like DXTW or FAHF etc. Would you happen to know or these are compatible or what these extra codes are indicating? If I ask something too much off topic, my bad and excuses from me
@@hsmautoservice158
These are usually manufacturing references...
Try the same part number, and even the part numbers are sometimes superceded throughout the years while the car is produced...
I have a question,
When you put a second hand ECU in the car do you also need to put the milage of the old ECU in to the second hand ECU?
At the moment I’m going to change my ECU on my Opel Astra G (ECU Delphi 12214860)

Hello I'm having the exact problem with my astra and have been told new ecu can you give me advice on who to use please I'm in Birmingham and how much for someone like yourself to do it..Thank you
Hi. Thanks for the video. Very educational since I just bought an Astra H and I want to reset the ECU. Now I don't find anywhere any tutorial to how to enable the OPC/VXR Scan (needle sweep). Since you are clearly more experienced with the OPCOM, do you know if it would be possible to do that with the OPCOM and if yes, can you tell us how or make a video please? Thanks a lot and sorry for the bother
Hi
I never attemp such thing... so don't know if is possible to do it with opcom...
But you can easily check it...
Thank you for watching and for your comment, really appreciated!
good video, as always. if you could help me wit a sugestion... astra h 1.7 cdti ocassionaly lights up "car with spaner" ligt, and goes to safe mod, and if left idling, after a few seconds goes back to normal. if accelerator pedal is kept pressed than never returns to normal. live data says that boost presure goes to max(307 kPa) but MAP sensor voltage stays normal at 2,03 volts. any thougts? thank you
Hi
Yes... 307 is a quite high...
Either you have a stuck geometry, or a bad sensor...
Check the turbo...
Thank you for watching and for your comment!
@@LMAutoRepairsturbo is without geometry, just a wastegate... what confuses me is that sensor voltage is good at that time. is there a posibility that ecu is somehow under some conditiions usses some preprogramed parameter and shows such abnormal boost level and consequentaly goes to safe mod? what i noticed is that if i disconect egr, map voltage stays at2.03v but live data shows manifold pressure 307kpa.
Hi mate, yours is a very clear and informative video.
I have a a similar Astra H with dead CIM and ECU and other DTCs.
Instead of taking it to auto electrician I bought exactly same hail damage Astra which is a total loss which drives pretty well to use as a donor car.
I have got Autel Maxi Syd Pro scanner too. Just in case.
My plan is to swap the ECU, CIM, REC, UEC and use the key from the donor car.
Is there anything else apart from above parts that I have to swap to get the car running?
I assume that no programming will be required if all the paired devices are swapped from the donor car.
Your expert input will be highly appreciated. Thanks
Hi
You might need the cluster as well... can't remember know from the top of my head which modules are part of the security system...
But try without it and see...
Thank you for watching and for your comment!
👍👍👍
@@LMAutoRepairs thanks for the quick reply. I was completely missing the cluster.
I think there should be an immobilizer box somewhere too. Not sure though.
I did an ECU swap in a CE Lancer and it had a separate immobilizer box.
Will try to post here after getting the job done.
Thanks

You need a tool capable of reading the code from that ecu, or capable of reset it...
Carprog is usually a good solution for Vauxhall...
Thank you for watching!
LM Auto Repairs hi thanks for reply, I have purchased carprog. Hopefully that will do it. Paul
I had problem starting the car astra H , changed the crankshaft sensor all the codes were cleared, car started without any problems for an hour and k now it gone back to same problem with new codes..
Hi there I have a problem with my Vauxhall’s zafira 1.9 CDti I keep getting ecn code 060631 but can’t find any we’re what this code relate to I would appreciate any ideas thank you
Hi
I presume that is retrieved with the pedal test...
Should be read as a normal code, as far as I am aware... you just ignore the last 2 digits... so, in your case P0606
Points to an issue with the ecu itself...
Hope that helps!

Hello, thanks for the video, I was wondering if you could help me with a error code since my abs module have been replaced with a s.h. one. Yaw sensor longitudinal C0287-00, I also changed the sensor but still the error the abs and esp lights are off. I think the esp is turned off by the abs module
I have a question about this procedure. Is is necessary to update the odometer information on the ECU to match the instrument cluster?
PS: Gosto muito do teus vídeos. Continua o bom trabalho. Podias referir em algum dos teus vídeos onde adquiriste o conhecimento e experiência para realizar estes trabalhos? Cumprimentos de um português.
No... on this cars the mileage is not stored in the engine ecu... or at least is not relevant...
Na verdade aprendi sozinho... sou mais ao menos bom nestas coisas... sabes come é...
Obrigado!
Very interesting video. Will it still work if the replacement ECU hasn't been reset.
Great video! Would this ecu replacement procedure be applicable to a 2014 Opel Astra GTC?
Hi
I believe the procedure still the same on that year...

Hello thank you for your video, i have a couple of questions.
1, is this the same procedure for corsa c 2000 reg?
2, does the old original ecu have to be reset before new one fitted?
3, dont you have to write the VIN into the new ecu and code functions (what the vehicle is fitted with)?
Thank you. Ive read a previous question you answeared for question 2 lol

Hi, Great work on your Video's, nice and simple.
I have a a couple of questions regarding the ECU on a 2004 Astra.
I changed the whole Ecu kit from a scrap yard.
Ecu, key reader and transponder chip, I have the opcom software and carprog.
Are I better to put the original key reader back in and reset the scrapyard ecu, then program it to the original key reader.
I got both security codes via the carprog so that is no problem.
I could leave the scrapyard Ecu as the car is running fine, but I want to make another key, I have a brand new transponder chip, but also I have two original chips with the original ecu set.
So I guess my question is, should I reset the scrapyard ecu, put the cars original key reader back in and reprogram that ecu to the original key reader, this will let me use the two original key chips again.
Any advice would be great.
Steve. 😃

Hi
If you have both pins, you can do what suits you better, as you can play with all the parts once coded all with the same pin...
Hope that helps.
Thank you for watching and for your comment!
@@LMAutoRepairs thanks for the information.
Also if I want another key ( not the blade or the transponder chip) the circuit board thats inside the remote, will I need to program this part also or just sync it via putting it in the ignition and pressing the remote button until the doir locks go up and down. I understand that there are two different frequencys for these remotes as I have about ten at home from dead ECUs
I appreciate you feedback mate!😃

Not sure... I mean, one thing is resync a previous programmed remote... another thing is program a new remote...

hello thx for video again.. so if an ecu is dead first reset it with your pin.. then install the second hand and with carprog get the pin and again reset it. after that reprogram the second hand ecu with your fail ecu pin? is that right? the thing is why on ebay they sell ecus with key dash and sterring? do i have to change all these with ecu? thx for your time man.
Hi
That's correct.
If you can execute the procedure, the ecu is all you need... those kits on eBay with keys etc... if if you don't have how to do what I show on this video...

Hello Buddy @LM Auto Repairs,
I have problem with my Astra H, always i see the fault codes like P1616-CIM(wrong enviroment identifier) and P1614 (Wrong transpoder key), i have the opcom from our friends from east. The problem is with closing the doors, when i put the key on start, it works fine, when i turn on engine and turn it off, the central lock doesn't work, one solution to repair this to the next start is unpin the battery.. Do you have any solution, should i restart my ECU ?
Hi and thanks for your great videos, I have a astra 1.3 cdti mk5 z13 dth, I suspect the ecu is not commuinicating with the pressure regulator valve on the high pressure pump
can this be solved by resetting the ecu or will it need a new /2nd hand one/
Thanks
Dave
Reset most likely will make no difference...
You you suspect... don't leave it at that... make the checks to ensure that the issue is not the valve, wiring or something else...😉

Good morning. I have old pin extracted with car prog.and new carpass.

Thanks for this informative video. For the second hand ECU that is used on the Astra H, was this reset while on the donor car? If so, this would be difficult to do for most ECUs that are found on cars in wrecking yards.
Brian
This reset doesn't necessarily need to be done on the donor car... it can be done on the car you going to install it... as far as you have the code or have a way to retrieve it... (watch my other videos...)

Hi mate ive got an astra h With p1614 fault for immobiliser can you help?
Hello - I have watched so many of your videos as no one else on TH-cam or the net seems to understand a specific issue I have faced for 3 weeks now. P0606 ECM code on a K12 Micra DCI. Any ideas where to start, I checked most of the wires to the ECM but I dnt want to strip all the looms to look for shorts. Do you think a faulty sensor like the crank or cam will trigger the code or its a genuine short somewhere that I must look really hard to find. Trying to narrow the issue down. Greetings from South Africa
That code points to a faulty ecu...
Obviously test everything, powers, grounds etc...
Check ecu outputs as well...

However, we had changed all the intake and the outtake camshaft positioning sensors. all the wiring connection to the ECU are ok. Now the last guess is the ECU. Is it the same procedure for the automatic car just to change the engine ECU
Hi
Thank you for your comment.
the procedure is the same, obviously if you get a second hand ecu from a manual, you then need to code it for auto.
Other than that is the same.
great video i take its same procedure to the cim or is it a different procedure and do you have deleat the unit from donor vehicle is this a must procedure before removal thank you
Similar procedure, yes...
👍👍👍
@@LMAutoRepairs also does the unit has to deleated 1st before you remove from scrap vehicle or is this not important as long as I have the security pin of vehicle it's going in thank you
No, you need the original pin to clear the unit... it needs to be on a "blank" state, before you attempt to program it...
@@LMAutoRepairs aha got it so if I get a cim with pin then I can fit on my car and clear it 1st then I use the pin for my car to reprogram it to my car I think I've got it thank you for reply I always love watching your videos keep up the great work
Yes... that's correct...
👍👍👍
So it pairs new ECU by going through the CIM? Like it will transmit all information with your security code etc? you only need new ecu's security if they forgot to reset when removing?
Yes...
If the modules had been reset prior, you only need the security code from the car is going to be installed on...

Alright cheers buddy 👍
Hi, nice video.
I notice you are using Op-Com software which i have, but have only used for reading fault codes on my 2007 1.8 Astra. With this I have diagnosed faults with my VVTi system and have replaced all crank pulleys/sensors etc relating to the VVTi but i still get the same 'Exhaust Camshaft Position' error. At the last MOT my local garage (whom a trust) said that it seems that there is a fault with the ECU. The car runs okay but always in 'limp mode' with the car & spanner light on.
After watching your video i plan to get a reset or blank ECU and reprogram it with my Op-Com to work in my car. Will I need to save or back-up anything from my original ECU before i can re-program the replacement?
Cheers

Hi Kevin!
Save all the coding settings...
It's all you need to save.

Hi mate, the procedure is the same with PEPS cars too? I've got a Z20LEH Astra OPC and i've read out the fault codes and it says u2105-00 no communication with ECM. The car stalls when it idles several times and also got rough idle when the engine is warm.
Also my other question.. what if i buy a second hand ECM but it's not reseted before? Should i do the same as in the first part of the video?
Hi
You don't need to reset the original ecu...
If you get an ecu that is not reset, you need the pin code to reset it, so you can then program it back to your car using the pin from your car...
Thank you for watching and for your comment!
Hello buddy. I have a question. My Astra H 2008 z20ler has a code P0621. The engine doesn't start. I have repaired the charger. The engine was working very well nonetheless at the time eliminate of the cables in battery the engine stops. Since this moment the p0621 is available. Do you know if the ecu internally is damaged? we take off cables at the time the engine is running the engine stops and after that the code is available the engine doesn't start.
That code refers to a code for the alternator light wire... if that makes sense...
Double check connections, and that the alternator you installed is good...
That however, should not prevent the car from starting...
Something else is causing it...
Go through everything you have disturbed while changing the alternator...
Check grounds, connections, etc...
👍👍👍
Hi, I see that the 2 security codes are the same in your video. Will this always be the case. If I buy a second hand ECU will I be able to use the security code I have for the current ECU?
Chris Headland
Hi
If the ecu you buy has been already reset, yes, you can and need to use the pin from your car...
And how it would be, if the new(used) ecu has not been reseted from the seller?
Will it work to program it to my car? Oder do I need the Security Code from the seller for his ecu and can i reset it then on my car and program it to my car?
Thanks
That's correct...
You need the pin from the ecu if has not been reset...

In case you do not have access to the ecu, for this broken one, can I install another ECU of second hand that has been previously reset, thanks !!!

hi, my ecu has gone bad after a jump start, I got another ecu that came with a replacement engine I had to fit, only problem I don't have the pin for the replacement ecu, I tried mpps to read data but it wont connect to my tigra B, is there any other cheaper way to get the pin code for the replacement ecu, thank you
Hi
This are your opinions...

It might be other tools capable of the same thing... just do your research! 😉
Hope that helps.
Thank you for watching!
I really appreciate please could you tell me what program you used?
Here was Op-com...
Thank you for watching and for your comment !
Hi mate, I just got my Op-com 120309a with chip PIC 18F458, but the cd software was defect, have you fw 1.45v, or where can I find? Thanks!!👍
Loads of places out there...
Just Google it...

Hi tell me is it possible to use the manual ecu in automatic car astra h z18xe? if yes what software must i use?
Thank you so much for this video

Hi
! I have a Astra H 2007 and my engine stops on changing back to 2nd gear ! Also my door lock is not working for 2 of my doors ! Last time i went to service to install a subwoofer, and they connected the diagnostic port idk for what ! But since then my engine pass the 2nd gear when i accelerate and when is comming back to 2nd engine stops ! Can i get a little guidance with it ? Can it be a faulty software on it ?
Scan the car to start with...

Hi! I bought a second hand ecu from scrap yard, not reseted. How can i reset it and were i can find security code if that car doesn't have carpass?

👍👍👍
I didnt know that but ive had them all on a live feed and they seem to be working the egr is working on the live feed so im going to sort the wasge gate on the turbo and if still no boost going to the egr
Please where can I get ECU software version 19, as I can see on your OPCOM connection screen? My ECU (all the same), is version 15. I will reprogram by carprog, but where to find/download it firstly ?
Great video, just one question what is the purpose of resting the old ECU first?
Hi
None really, just if you decide to sell it, or get it repaired and then sell it, you don't need to reveal your car's pin code.
So you can sell it "ready to program".
Thank you for your comment.
One unrelated question: Do you know on what temperature that z16xep engine works?
90°c and over....
From where I can get the password I mean the security code to reset? Many thanks for videos mate.

Can I then change the odometer value for my Astra H if I reset the ECU?
If I try to change the odometer value it says that the value can be changed only once.
It lets me to enter a new value but if I press OK the value on the odometer doesn't change.
I guess the previous holder of my car had already changed the value once before I bought it.
May be that is the reason why I can't change it now.
What do you mean?
The message is somewhat misleading. What it actually means that you can only change it as long as it's in factory state (ie. odometer is actually 0 or at least below 50-100 kms/miles, depends on factory and model). But once the odometer has some in it, you can't change it at all, or only set it to a higher value - regardless of whether it has been change any time. Of course there are tools that will allow you to change the odometer even in this state, by circumventing the factory constraints.
So, you're still using the security code from the original, defect ECU (ie. that came from factory with the car you're sitting in now), even when the ECU in the car has been replaced and the actual one is now from another car (which obviously had a different security code originally)? You don't have to use the security code from the new ECU, but that of the old one?
Hi
The original pin of a replacement ecu is needed in order to reset the ecu...
Once that is done, you need the pin from the car you want to install it on, in order to program it...
You can't use a different pin to program it...
Hope it makes sense...👍
@@LMAutoRepairs But if the replacement ECU is already reset, then you only need the security code of the car it will be built into, and use that in the immo module, right?
Correct...
👍👍👍
@@LMAutoRepairs Thanks
What do you do if the new second hand ECU has not been reset before it was removed from the old car?
Also what if the second hand ECU does not come with the security code?
In that case you need to retrieve the pin from it...
👍👍👍
@@LMAutoRepairs Do you have a video showing how to retrieve the code directly from the ECU?
Do you need to use a chip programmer to read the eeprom?
Hi mate, do you also know the steps of activating the BC for a 2005 Astra?
🤔
Don't think so...
Thank you for watching!
hi to activate it u need opcom then you have to go to bid(screen) section and program it.to this section for your screen there are some codes for exp 05,06,07 if i recall you have to choose 5. be carefull to choose the corect linear resistance or voltage.. please google astra bid index code.
What software are you using to reset the ECU and IMMOBILIZER?
As per the video...
Op-com...
👍👍👍
I have a zafira b 2006 and I cannot program key on any of my machines what am I doing wrong ?
I have Astra H 2005 model but I finding it difficult to reprogram my ecu what type of machine are you using for the programming because it says my software is not updated even though I bought the machine less than a year
Op-com should be able to handle it...
Thank you for watching!
do i need both pin codes for both ecu's ??? or the one stored in the REC is enough ??
If the replacement ecu is not reset, yes...
As per the video, you need both pins...
Thank you for watching!
How did you know the security code ?Is it a security code of the ecus car , or of the programe you are using ?
It is the code for from the car...
👍👍👍
@@LMAutoRepairs where do we find it ?
th-cam.com/video/L-WSXbthTBs/w-d-xo.htmlsi=eZxsKWqn2FFV5YhP
Why do u need to reset or deprogram the damaged ecu when u gonna replace it anyway for another one ?
You don't need if you are not plan to use it again...
👍👍👍
Hi from greece i watch all your videos nice job . I have zafira b 2006 model and today i replace with second hand my cim module i reset my ecu with security code from carpass and i try to reprogramming my imo but if i try to give the security code from my carpass again my opcom say that the control unit not accept the security code either timed out or got an illegal response .i have not change my ecu only the cim module i go step by step what your video says but i stack in security code have you idea what is wrong? thanks
subarulis angelo
Hi
First of all thank you for watching my videos, much appreciated!
Okay, so you say you got a second hand CIM, and when you try to program it using the pin code from your car, it fails.... correct?
Will i delet all staff from car like chip tunning ??
No...
This only clears immobiliser...
Thank you for watching!
Hi my vauxhall zafira 1.6 57 plate ecu is faulty and I am changing ecu fuse box and clock cluster and ignition will I need to reset my immobiliser thanks ..........kevi
Most likely yes...
Thank you for watching and for your comment!
My rear view mirror defroster is constantly always on and cannot turn it off: only when the key is taken out of the car. Any ideas what it could be? Also, I’ve also tried fitting in a stereo so I’m assuming maybe wiring issue?
Thanks for the video tomorrow I need to replace my astra h engine ecu if I get one from scrappy can I reprogram as you have or does the old one need to be reset in the old car first
steven fairley
The old ecu does not need reset, the second hand ecu that you are going to install needs though.
You also need the pin code from your car, and the pin code from the car you are taking the replacement ecu from... or have the tools to get hold of the pin.
lmsvvavr thanks this is the problem It will be a scrap car so no code iv got the code for my car
steven fairley
Unfortunately there is no other way...
Or you have that pin, or you have how to extract it...
th-cam.com/video/L-WSXbthTBs/w-d-xo.html
I'm replacing because I cannot access engine ecu via opcom it it will not turn over when forced to turn over by power to starter direct it does not run its like the ecu has no power speedo didn't move on towing or rpm on towing in gear other models communicate cim stereo abs ect but have fault code of cannot communicate with cars engine ecu
steven fairley
Have you checked wiring, connectors, fuses, earth points etc...
If your problem is indeed the ecu, when you put the second hand one you will have communications... even though you will not be able to start the engine due to the immobilizer.
If you still have no comms then your issue is another one...
Hi can anyone tell me what is the website call that you used to program your car and did you used a laptop
Thanks
