Self-adjustment
Hint: After replacing the control module or damper motor, and when a damper motor or link has been removed, carry out self adjustment to define the damper motor limit positions.
- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
Activate self adjustment.

Verification
Hint: After the repair it is necessary to check that the fault has been rectified.
- Ignition off.
- Connect the connectors, install the components, etc.
- Ignition on.
- Blower motor on.
Check that damper motor position changes by changing control on climate control module (CCM). The values given below are the standard values that the damper motor positions should give.
Note! Blower motor must be in operation to activate the damper motors.
- Left/right temperature damper motor and defroster, 0-100%
- Recirculation damper motor, 40-100%
- Floor/ventilation damper motor, floor only approximately 39%, ventilation only approximately 87% and floor/ventilation approximately 71%.
Does damper motor work?
Yes - Verification completed
No - Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing
No - Attempt New Test
