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 TC23XX-24F microcontroller
This module has no separate EEPROM: the crash data is kept in the data flash (DFlash) of its Infineon AURIX TC23x microcontroller (TC23XX-24F). Read it over the DAP / JTAG debug interface with a programmer that supports this MCU.
Data-flash dumps of the Infineon AURIX TC23x that we have processed are 131,072 bytes (128 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 TC23XX-24F memory of the M9V2-14D374-AB module with your programmer and save the dump.
- Upload that file here and enter the part number M9V2-14D374-AB.
- 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.
