What does this fault code mean?
The climate control module (CCM) loses contact with the defog damper motor on LIN bus 2. Without a reply, it cannot control defogging of the windows and mirrors. The fault code may appear together with fault codes for other components on the bus.
Possible causes
- Break in LIN bus 2 wiring between the module and the defog damper motor
- Poor contact, corrosion or loose connections at the connectors
What you can do
- 1Check that the fuses are intact
- 2Check that the connectors to the damper motor and the climate control module are secure and clean
- 3Check with a multimeter that the LIN bus 2 wires are not open when the connectors are disconnected
- 4Try the defog function and see whether air reaches the windows
- 5If you have a diagnostic tool, read the damper motor status in live data while you start the defog
Symptoms you may notice1
- Mist on the windows and/or the outside mirrors
General guidance for car owners. Diagnosis on the car can point to a different cause.
