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