Verified module. We have already processed this module type and hold a reference pattern for it, so the reset is done straight away.

Reading the XC2336A-56F microcontroller

This module has no separate EEPROM: the crash data is kept in the data flash (EEPROM emulation) of its Infineon XC2000 microcontroller (XC2336A-56F). Read it over the bootstrap loader or DAP with a programmer that supports this MCU.

Make two reads and compare them before you upload, and keep the original file as your backup.

How the reset works for this module

  1. Read the XC2336A-56F memory of the BRE7 57 K30 module with your programmer and save the dump.
  2. Upload that file here and enter the part number BRE7 57 K30.
  3. We remove the crash record and return the repaired file, usually within minutes.
  4. Write the file back to the module and clear the fault codes.

Before you fit it back: clearing crash data does not repair the car. Deployed airbags, used pretensioners and damaged sensors must be replaced and the system checked fault-free before the vehicle goes back on the road.
