How can I extract or find the read/write password in a PCR2.1 ECU?

[feming]

Hi there,

how can I extract or find the read/write password of a PCR2.1 ECU?
I have a MPPS V22 with TriCore adapter.

Is the read/write password in the EEPROM or in the Flash?

I need it to do a full read of the flash in order to IMMO-OFF the ECU.

Best regards

You need to read the EEPROM and unlockit ! Then write it back the EEPROM to be able to read and write the flash!!
Here is a program that unlocks the EEPROM!!

Thanks a lot for your reply.
I have already:
- unlocked the ECU
- able to read/write over OBD

But the Flash over OBD is not a "full" flash.
I'm stuck in trying to read the full flash in bench mode because I can not extract read/write password.
