Was bedeutet der Fehlercode?
The central module receives no signal from the steering wheel module (SWM), so the controls in the steering wheel cannot be used. The cause may be a short circuit or break in the LIN wire, or a fault in another unit on the same network. It can affect the wipers, the washers, the indicators and cruise control.
Mögliche Ursachen
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Fault in another unit on the same LIN network
Was Sie tun können
- 1Check that the wipers, the washers and the indicators work, and note which ones do not
- 2The wires to the steering wheel sit close to the airbag. Have a workshop check them, because work there involves the airbag
- 3If the fault remains, have a workshop replace the steering wheel module (SWM)
Symptome, die Sie bemerken können4
- The windscreen wipers do not work
- Washing does not work
- The indicator switch does not work
- Radio and phone controls on the steering wheel are inoperative
