Co oznacza ten kod błędu?
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.
