Activated Too Long. Permanent Fault

Activated too long. Permanent fault

Checking component




- Ignition on.
Check manually whether any of the climate control knobs are stuck or have locked in the depressed position. Check that the button LEDs light and go out when the button is pressed.
Read off the activation for the lower electrical switch and check that the values switch between ON and OFF as the button is pressed for each switch.

Note! Note the following about activating the lower switch.
- Adjustable head restraints. After four activations in quick succession the function is blocked for approximately 2 minutes. After this time when it is blocked, the activation can be carried out again. The head restraints are folded back manually.
- Auxiliary lamps. The electrical switch for auxiliary lamps cannot be controlled using this function.
- STC/DSTC. To activate / deactivate STC/DSTC the switch must be held in for a t least 0.5 seconds.
- Private locking of the trunk lid. The Private locking function for the trunk lid can only be activated with the master key in position II.
- Temporary disengagement of detectors (Deadlock position). The temporary disengagement of the detectors can only be activated with the master key in position I.

Remedy as necessary. If no fault is found the control unit for climate control must be replaced.

Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off.

Note! Wait at least 1 minute before "Ignition on". This is to allow the climate control module (CCM) to carry out a new diagnostic.

- Reinstall the connectors, components etc.
- Ignition on
- Read off diagnostic trouble codes (DTCs).
The fault is no longer present if the status of the diagnostic trouble code (DTC) has changed to intermittent.





Does the status change?

Yes - Verification completed

No - Information
