When the ignition is switched on, the airbag warning lamp -K75- lights up for about 3 seconds and then goes out again.
If the airbag warning lamp -K75- does not go out again, then there is an open circuit in the voltage supply to the airbag control unit -J234-. Fault rectification → Chapter.
If there is a fault, the airbag warning lamp -K75- lights up again.
