Was bedeutet der Fehlercode?

The central electronic module (CEM) has registered that the signal to the left seat heater is too low or missing. The fault is intermittent, so it has occurred before but may not be active now. The cause may be an earth fault or an open circuit in the wiring to the seat heater, or a low signal when the communication link is not active.

Mögliche Ursachen

Earth fault or open circuit in the wiring to the left seat heater
Low input signal when the communication link is not activated

Was Sie tun können

1Clear the code and road test with the seat heater switched on to see whether the fault returns
2Check that the wiring to the left seat heater has no chafing or pinching, especially under the seat
3Check the connectors in the seat heater cable for loose connections and corrosion
4Check the fuse for the seat heater and replace it if it has blown
5Use a multimeter to check that the wiring to the left seat heater has no break and no contact with ground (the body)
