Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information CCM-0020

Condition




The diagnostic trouble code (DTC) is stored if the climate control module (CCM) detects that a function button on the dashboard environment panel has been activated for longer than two minutes.
The climate control module (CCM) can detect a maximum of two buttons being pressed simultaneously. If more than two buttons are activated for too long simultaneously, the functionality for all the buttons may be lost.
The diagnostic trouble code (DTC) can be detected at key position 1 or 2 (not key position 3).

Substitute value
- The climate control module (CCM) does not permit the button function to be activated before the button has returned to the normal position.

Possible source
- One or more function buttons are stuck in the pressed-in position
- Unintentionally long activation of the function button.

Fault symptom[s]
- Buttons/control knobs on centre console (Climate)/No/reduced/incorrect function
