Hi all,
Sorry for the long post.
Info about the car/modules:
Brand/Type: Renault Zoe Q210 (X10)
VIN: VF1AGVYA050672558 (Dutch license plate, imported from Germany?)
Engine code: 5AM-450
Modelyear: 26-03-2014
UCH (body) P/N: 284B18853R BCM95 L3 Int (simular to Fluence/Megane 3)
PEB (inverter) P/N: 291A50697R
EVC P/N: 237D40054R
No DTCs/errorcodes.
I got a Renault Zoe (X10) from 2014 where someone else replaced the PEB (inverter) module as it was defective. The used module was first installed with the eeprom from the used module and afterwards the original eeprom has been placed on the PCB of the used PEB module. I would expect this is enough to make the car think the same module is placed in the car and to start, but it doesn't work...
Maybe they tried to repair the UCH (body) or EVC(engine controller) module and then broke the immo sync. Or something else, but it is not known what was attempted besides changing the EEPROM...
Problem is: car doesn't "start": when directly attempting to "start, "ready" is illuminated for a few seconds, then it flashes a couple of times. When using this procedure the DCDC 12V-voltage is activated and power steering works.
If you first turn ignition on and then try to start, "ready" will only flash a couple of times and nothing is activated.
When looking at the live data of the PEB module:
after ignition is switched on the "immobiliser code programmed" switches shortly to "yes", but after a few seconds it switches back to "no". And the protection state switches to status4. Renolink/DDT4all seem to decode this as that the ECM (EVC?) prohibits start authorisation... Can the EVC be in a "safe mode" because it has received an incorrect code from the other eeprom of the used PEB? And it only needs to have a 'reset' to reaccept the correct code? Flashing with newer software didn't fix the problem.
Is anyone familiar with the PEB modules of Renault? This is the first PEB immobiliser problem I encountered so I'm not familiar with it. Does the PEB communicate directly with the EVC? Or is the UCH the central point speaking with each module individually?
From the technical information from Renault I know that when installing a new PEB module, it needs to be coupled to the immobiliser system of the car, which seems to be controlled from within the UCH module. (But this can only be done once it seems, and only by the dealer with an online connection with Renault. It's not a pass-thru feature unfortunately...) But why does the PEB module seem to be complaining about an immo error with the EVC module? Or is this a translation error from the Renolink/DDT database?
Or is maybe some immo information stored in the flash memory of the PEB module? This could explain why only replacing the eeprom didn't work.
I don't have the EEPROM data from the PEB module unfortunately. For this I need to open-up the PEB module which I try to prevent as this module is also water cooled.
I tried to virginize the UCH and reprogramming it to the car, but it seems the PEB sync step is not incorporated in my universal tools. EVs are poorly covered.
I hoped a software update was available for the PEB, as a software update sometimes resets the data and allows recoding and rematching to the car. But no software update was available via Renault Pass-Thru. Furthermore, UCH flashing is not available with Renault Pass-thru, so this wasn't an option. I did a software update of the EVC module, but unfortunately no difference.
Also tried to contact someone with Renault Clip Diagnostics Online, but people seem to be scared of programming used modules to a Renault... They think it's not possible and see it as wasting time? I wanted to make the UCH virgin and then program it like a new module (as the UCH seems to be the central node of the immobiliser system.) This will allow recoding/syncing of all immobiliser functions, I expect.
Does anyone have experience with this? Or any tips to sync/couple the PEB to the immo system without CanClip online with dealer access?
I would like to help my customer as a new module costs 3000(!) EUR and reusing modules is also good for the environment/'circular' economy.
Thanks in advance!
