I had to replace my front seatbelts and ended up getting new ones. I dumped the data from my controllers and transferred it over to avoid triggering CP and having to parametrize. However, it also copied over the number of activations and I wanted this to say 0..

MCU is Infineon XC2336B-40. I read it with Xprog 5.84, pinout attached.


Flash0 is the same for all devices regardless of HW no. It contains nothing interesting and does not change.

Looking at the flash1 data I noticed it's split into banks denoted by ASCII "BNK".

BNK0 (0 to 0xFFF): identification and logistics
BNK1 (0x1000 to 0x4FFF): operation data/history
BNK2 (0x5000 to 0x5FFF): ?
BNK3 (0x6000 to 0x7FFF): ?
BNK4 (0x8000 to 0xFFFF):?

Transfer 0x1000 to 0x4fff (All BNK1s) - to clear tightenings. I'm not sure what the other banks contain. I think CP and parametrization might be mixed in.

Attached is a clean BNK1 file.

You’re doing the work the hard way. Leave the PCB from the old belt - it’s very easy to remove or match new tensioners online with ODIS.
