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 TC22XX-16F microcontroller
This module has no separate EEPROM: the crash data is kept in the data flash (DFlash) of its Infineon AURIX TC22x microcontroller (TC22XX-16F). Read it over the DAP / JTAG debug interface with a programmer that supports this MCU.
Data-flash dumps of the Infineon AURIX TC22x that we have processed are 98,304 bytes (96 KB).
Make two reads and compare them before you upload, and keep the original file as your backup.
How the reset works for this module
- Read the TC22XX-16F memory of the 98820-6GR0C module with your programmer and save the dump.
- Upload that file here and enter the part number 98820-6GR0C.
- We remove the crash record and return the repaired file, usually within minutes.
- 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.
No programmer? You can also send us the module. More answers in the FAQ.
