Was bedeutet der Fehlercode?

The CEM supplies the left emergency brake light directly from one output. The code is set when a faulty signal lasts for a while with the brake light activated. The cause is a voltage supply wire shorted to ground.

Mögliche Ursachen

The voltage supply wire is short-circuited to ground

Was Sie tun können

1Press the brake with the ignition on. If the left light stays dark the fault is likely permanent; if it worked before, it is intermittent
2Check that the brake light fuse is intact
3With the ignition off, use a multimeter to check that the voltage supply wire has no contact with ground (the body)
4Look for chafing and pinched spots where the wire runs in the rear wiring harness
5If the fault returns, have a workshop with diagnostic equipment check the circuit

Symptome, die Sie bemerken können2

The left brake light and tail light do not work
The lights stay constantly on
