Was bedeutet der Fehlercode?

The central electronic module (CEM) has registered a signal that is too high or faulty on the wiring to the left seat heater. The fault is intermittent, meaning it comes and goes, so it may have arisen earlier without being active now. The cause may be a short to positive in the wire or a faulty output stage.

Mögliche Ursachen

Short to positive in the wiring to the left seat heater
Output signal constantly high while communication is active

Was Sie tun können

1Clear the code and road test with the seat heater switched on to see whether the fault returns
2Check the connectors in the cable to the left seat heater for loose connections and corrosion
3Check that the wiring under the seat is free from chafing and pinching
4Check the fuse for the seat heater and replace it if it has blown
5Use a multimeter to check that the wire to the left seat heater has no contact with battery voltage
