Hva betyr feilkoden?
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.
Mulige årsaker
- Short to positive in the wiring to the left seat heater
