Hi everyone,

I'm a newby in EV and I recently purchased and repaired a KANGOO ZE Maxi 2012.
I did a swap of the DC/DC part of the PEB and a few other minor repairs in the wire loom of the car.

The mainboard is in the middle of the PEB.
It has two connectors and two flexibles attached to it.

Now I was wondering, as I read different problems about that "once programable" vincode problem, how they do it.
It has to be stored elswhere than in the microprocessor of the mainboard. That Infineon tricore can store data an can be rewritten.

And with the help of a friend with a lot of experience in electronics who pointed out the nearby position of a spi eeprom.

The electronics are mostly related to the network except for the Altera Max II and the Infenion (probably the heart of this carpart).
The VINCODED IC is located below the Infineon processor on the left side (next to a square testpoint)
It's a 8 pin IC from ST-Electronics labeled K217H DM (or BM) 95256.




Can anyone confim this?

It would be fairly easy to transfer this IC to a new mainboard. If it is this one ofcourse.
I think it is a job that would safe a lot of people al lot of money.

Other thoughts are also welcome...

Regards,
Conn

Hi there,

I have had this repair done so yes it is possible. You are right the vin code is not stored in the infineon - i cant remember exactly which smaller one it is located in but here in the UK we have specialist repair garages that can do this work. It enables you to buy a 2nd hand PEB and have the chip swapped over and then it will work in your car. We have tried reprogramming the chip with the correct VIN, and also writing new chips but this was not successful, we found some checksum bits, worked out the checksum used but it did not accept it that way, only transferring the original chip.

The fix is referenced in this video

So yes you are correct, it can be done.

Cheers.

Just looked back at the correspondence with @mikeselectricstuff who worked on one of these projects with me, and he advised:
The ST M95256 8-pin chip next to the big Infineon Tricore chip is probably the memory holding the data.

He will probably confirm when he sees the tag.

Cheers.
