Hva betyr feilkoden?
The climate control module (CCM) receives no message from the rear seat heating switch, so it cannot control the heat there. The fault is caused by interference in the communication between the two units.
Mulige årsaker
- Interference in the communication between the switch and the climate control module
- Loose or poor connection in the wiring to the switch
Hva du kan gjøre
