Was bedeutet der Fehlercode?

The CEM controls the interior lighting through an output and has registered too low a signal from it. The cause may be a short to ground, a break in the signal wire or a blown fuse, and then the interior lighting does not work.

Mögliche Ursachen

Signal wire to the passenger compartment lighting shorted to ground
Break in the signal wire to the interior lighting
Blown fuse

Was Sie tun können

1Check that the fuse for the interior lighting is intact and replace it if it has blown
2Check that the interior lighting switch is in the auto position
3With the ignition on, switch the interior lighting on and off: if it does not respond the fault is permanent, and if it works the fault has occurred before
4With the ignition off, use a multimeter to check that the control wire has no break and no contact with ground (the body)
5If the fault returns, have a workshop repair the wire
