What does this fault code mean?
The defog damper motor sends an incorrect response to the climate control module (CCM) over LIN bus 2. The fault is in the motor or its control module, so defogging of the windscreen may not work as intended.

- 2Check that the damper is not blocked or stuck
- 3If no other fault is found, have a workshop replace the defog damper motor
- 4After replacement the module has to be identified and calibrated, which a workshop does with diagnostic equipment
- 5Clear the code and road test the car to see whether it returns
