With this special function one can
-
Read/Write EEPROM memory of an airbag module
-
Clear the crash data of an airbag module
For some airbag models it is not enough to clear the trouble codes (using “Clear DTCs” diagnostic request) and the crash data stored into device’s EEPROM should also be cleared.
For some models (see “Covered units:” below) crash data can be automatically cleared (using the “Clear crash data” function) from the device’s EEPROM, but for some models the user has to do this by hand (read EEPROM memory (using “Read EEPROM” function), find where the crash data is stored, change data, write EEPROM memory back (using “Write EEPROM” function).
