What does this fault code mean?
The climate control module (CCM) has registered that the rear window defroster button has been pressed for too long. This can be because the switch has stuck in the panel, or because the climate control module is faulty. The fault may be permanent, or it may have occurred only once before.
Possible causes
- The button is jammed in the climate control panel
- Defective climate control module
What you can do

- 3With diagnostic equipment, follow the status of the rear defroster button in live data. The status should change when the button is pressed and change back when it is released
