Hva betyr feilkoden?
The steering wheel module (SWM), which takes in the signals from the controls in the steering wheel, cannot communicate with the central module. Several functions may be affected at once: the wipers, the washers, the indicators, cruise control and the steering wheel buttons.
Mulige årsaker
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Fault in another unit on the same LIN network
Hva du kan gjøre
- 1Check the wipers, washers, indicators, cruise control and the steering wheel buttons, and note which ones do not work
- 2The wiring to the steering wheel and steering wheel module sits close to the airbag. Work there involves the airbag, so have a workshop check it
- 3If the fault remains, have a workshop replace the steering wheel module (SWM)
- 4Indicators are important for road safety, so do not drive with a faulty indicator switch without having it fixed
Symptomer du kan merke4
- The wipers only work at the lowest speed
- Washing of the windscreen or rear screen does not work
- The indicator switch does not work
- Cruise control does not work at all
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
