Was bedeutet der Fehlercode?
The fault code means that the control module storing the fault has lost, or has disturbed, its link to the climate control module (CCM). The climate system may then behave wrongly: it can be fully off, or keep running even after the key is removed. The fault concerns the network.
Mögliche Ursachen
- No power supply to the climate control module (CCM)
- Broken ground wire to the module
- Contact resistance 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
Was Sie tun können
- 1Switch the ignition on and the cabin blower on. The fan should blow and its speed should be adjustable
- 2Check that the climate system fuse in the engine bay central fuse box is intact
- 3Check the CCM ground wire and ground point for breaks, play and oxidation
- 4If the fault returns, have a workshop check the CAN wiring. Replace the CEM only if testing shows it is damaged
