Was bedeutet der Fehlercode?
The control modules in the car communicate over the CAN network. The climate control module (CCM) registers a serious fault in the CAN communication, so it is blocked. If the power supply is still on, the climate control module can keep working for a short time after the key is removed.
Mögliche Ursachen
- Short circuit between the CAN wires
- Open circuit in one of the CAN wires
- Internal fault in the control module
- Internal fault in another control module on the same part of the CAN network
- If CAN communication is missing but the power supply stays on, the climate control module keeps working for a while (limp-home)
Was Sie tun können
- 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 and traffic
Symptome, die Sie bemerken können5
- The climate control system works even after the key has been removed
- The bottom button row of the climate system does not work
- The air conditioning compressor does not start or runs sporadically
- Mist on the windows and/or the outside mirrors
- The central locking does not lock to the deadlock position
Was der Fehler beeinflussen kann2
- 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
