This module is in our supported database. We check your dump before any work is done — if the crash data cannot be removed, the tokens go back to your account. You never pay for a job we cannot deliver.

Reading the 912B32 microcontroller

This module has no separate EEPROM: the crash data is kept in the internal EEPROM of its Motorola 68HC912 microcontroller (912B32). Read it over BDM (background debug mode) with a programmer that supports this MCU.

The 912B32 dumps we have processed so far were 768 bytes.

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 912B32 memory of the 98820-AV21A module with your programmer and save the dump.
  2. Upload that file here and enter the part number 98820-AV21A.
  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.
