Was bedeutet der Fehlercode?
The code concerns the signal to the front left reading lamp. It is set when the control module sees a bad control signal while the front left lamp is lit and the rear left lamp is off. The cause is either a short to ground or an intermittent break in the signal wire.
Mögliche Ursachen
- The front left reading lamp's signal wire is short-circuited to ground
- An intermittent break in the signal wire
Was Sie tun können
- 1Check that the connectors at the upper electronic module and at the roof lamp are firmly seated and not corroded.
- 2Read off the code, clear it and check whether it returns.
- 3Use a multimeter to check that the wire between the upper electronic module and the roof lamp has no contact with ground (the bodywork).
- 4Look for pinched or chafed spots on the wire, since these can cause an intermittent break.
- 5If the wire is in order, fit a fresh bulb in the roof lamp. If the fault remains, have a workshop check the roof lamp.
