Hva betyr feilkoden?
The airbag control module has received or sent incorrect messages on the high speed CAN network, and has shut itself off (bus-off). The fault is caused by an open-circuit in one or both CAN wires in part of the network.
Mulige årsaker
- Open-circuit in one or both CAN wires in part of the network
Hva du kan gjøre
- 1Read out all fault codes in the car and start with those relating to communication faults
- 2Have a workshop measure the resistance of the CAN wiring and check for open-circuits in the part of the network where the fault may be
- 3Have a workshop check connectors and wiring along that route and repair any damage
- 4After a repair, erase the code and see whether it returns
- 5Do not work on the airbag system yourself; have a workshop carry out all wiring and control module checks
Symptomer du kan merke2
- Text message in the display

Hva feilen kan påvirke2

Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
