Here shows a TRW airbag control module (SDM/SDU, part number 7A6499AK8055053). The user asks if a tool like OBDSTAR P50 can modify the part number to erase factory crash records.
The reply confirms:
Only supports installation/diagnosis, not clearing crash data.
Why it doesn’t work: Crash records are stored in protected, write-locked memory (EEPROM/flash) separate from the part number. Changing the part number only alters configuration data, not the locked collision logs. TRW/ZF modules are designed to retain crash history for safety and legal reasons, preventing easy tampering.
Sources:
TRW airbag clearing requires EEPROM dump editing (e.g., with CG100), not part number changes.
Autohome.cn and Chinese repair communities: Similar Great Wall/Haval TRW modules need advanced programming to reset crashes.
