Hva betyr feilkoden?
The fault code means that the control module storing the fault does not get a working link to the combustion preheater module (CPM), or the link is disturbed. The preheater module supports the parking heater, so the parking heater may stop working. The fault concerns the network rather than one individual control module.
Mulige årsaker
- Missing voltage supply to the combustion preheater module (CPM)
- Broken ground wire to the CPM
- Poor contact in the connections
- Open or shorted CAN wiring
- A module not intended for the car, such as a used unit with other software or hardware
Hva du kan gjøre
- 1Check that the fuse for the combustion preheater module in the engine bay relay and fuse centre is intact
- 2Check the supply wire for breaks and shorts to ground, plus the intermediate connectors for contact resistance and oxidation
- 3Check the ground wire to the CPM for breaks and loose contact
- 4If the fault returns, have a workshop check the CAN wiring. Replace the CEM only if testing shows it is damaged
Symptomer du kan merke1
- Parking heater does not work
