Hva betyr feilkoden?
The climate control module (CCM) is disturbed on the MS-CAN network, either by another module sending faulty messages or by the module's own messages. The fault may stop the climate control system from working at all. The fault code is set when CAN communication starts.
Mulige årsaker
- Short circuit between the CAN wires
- Open circuit in one of the CAN wires
Hva du kan gjøre
- 1Check that the battery is charged and that the battery terminals are clean and tight
- 2Check that the fuses are intact
- 3If you have a diagnostic tool, read the fault codes in all control modules and note which ones show communication faults
- 4Leave the CEM in place for a CAN fault unless troubleshooting shows it is faulty
- 5If the fault remains, have a workshop check the CAN network resistance
Symptomer du kan merke2
- Climate control does not work at all
- Temperature control or air conditioning does not work
Hva feilen kan påvirke2
- The control module shuts itself off (bus-off) and stays off until the power supply is broken
- At the next power-on the control module tries to communicate again
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
