Was bedeutet der Fehlercode?
The central module receives no communication from the cruise control switch in the steering wheel, so cruise control does not work at all. The fault may come from a short circuit or break in the LIN wire, or from an internal fault in another control module on the same part of the network.
Mögliche Ursachen
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Faulty operation of another control module on the same LIN network
Was Sie tun können
- 1Check that the cruise control buttons in the steering wheel do not stick and that they return when released
- 2The wiring to the cruise control switch runs in the steering wheel, close to the airbag, so have a workshop check it
- 3Do not replace the central module if other fault codes for a short circuit on the LIN bus are present. The fault then lies in the wiring or in another unit
- 4If the fault remains, have a workshop replace the cruise control switch
Symptome, die Sie bemerken können1
