Hva betyr feilkoden?
The SRS measures resistance in the stage 2 driver airbag circuit. If the resistance stays above the limit for too long, the code is stored. The fault is an open circuit in the wire, the connections, the airbag or the clockspring.
Mulige årsaker
- Break in the wire
- Contact resistance or oxidation at the connections
- Open circuit in the stage 2 driver airbag, where the igniter section has too high a resistance
- Open circuit in the clockspring
Hva du kan gjøre
- 1Read and clear the code, test drive to see whether it comes back
- 2Have a workshop check the connectors and the wire between the SRS module and the stage 2 airbag for breaks and contact resistance
- 3If the wire is intact, have a workshop replace the stage 2 driver airbag
- 4Do not handle the airbag system yourself; leave it to a workshop
Symptomer du kan merke3
- SRS warning lamp on
- SRS warning message shown
