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 TC27XX-64F microcontroller
This module has no separate EEPROM: the crash data is kept in the data flash (DFlash) of its Infineon AURIX TC2xx microcontroller (TC27XX-64F). Read it over the DAP / JTAG debug interface 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
- Read the TC27XX-64F memory of the 4M0959655S VW31 module with your programmer and save the dump.
- Upload that file here and enter the part number 4M0959655S VW31.
- 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.
