Was bedeutet der Fehlercode?
In the stage 2 driver airbag circuit, the SRS module measures resistance. If the resistance stays below the limit for too long, the code is stored. The fault is a short-circuit that can sit in the wiring, the connections, the airbag or the clockspring.
Mögliche Ursachen
- Short-circuit in the wiring
- Short-circuit at the connections
- Short-circuit in the stage 2 driver airbag, where the igniter section has too low a resistance
- Short-circuit in the clockspring
Was Sie tun können
- 1Read and clear the code, test drive and see whether it returns
- 2Have a workshop check the wires and connections between the SRS module and the stage 2 airbag for shorts to other wires in the circuit
- 3If the wiring is sound, have a workshop replace the stage 2 driver airbag
- 4Leave all work on the airbag system to a workshop
Symptome, die Sie bemerken können3
