Fault-tracing information
The Climate control module (CCM) has registered that the Damper motor module (DMM) does not respond correctly.
Corrective actions
- Check that the damper motors are correctly positioned in relation to their specific ID.
- Check that the damper motor is correctly installed.
- Check that the damper is not blocked and that is has not become stuck.
If no malfunction is found:
Replace relevant damper motor.

Fault-tracing information
After replacing the Damper Motor Module (DMM), the control module must be identified and calibrated.
Have any damper motors been replaced?
Yes - Identification
No - Verification
-------------------------------------------------
Identification
Hint: Identification of damper motors requires that the relevant damper motor is run to the limit positions. These runs can take up to 30 seconds. When identifying the damper motors it is important that a battery charger is connected.
- Ignition off.
- Reinstall the connectors, components etc.
Note! Ensure that nothing is physically preventing the damper from moving to its limit positions. If something is blocking the damper, an identification can cause problems which are extremely difficult to correct. Climate Control Module (CCM) and damper motors can be affected by the temperature. The vehicle should have normal room temperature when performing this service.
Carry out identification as follows:
- Ignition on.
- Click on the VCT2000 symbol. Wait until identification has been carried out.
- Ignition off.
Continue - Calibration
-------------------------------------------------
Calibration
Caution! When activating this function, calibration of the Climate Control Module (CCM) starts. After carrying out calibration read off of the diagnostic trouble codes (DTCs) starts.
Note! Climate Control Module (CCM) and damper motors can be affected by the temperature. The vehicle should have normal room temperature when performing this service.
Carry out calibration as follows:
- Ignition on.
- Click on the VCT2000 symbol. Wait until calibration has been carried out and diagnostic trouble codes (DTCs) read out.
- Ignition off.
This function controls the components that communicate with the Climate Control Module (CCM) via LIN bus 1 and LIN bus 2. If there is a fault in one of the LIN buses one or more diagnostic trouble code (DTCs), that affect the damper motors, will be stored.
Continue - Verification
-------------------------------------------------
Verification
Verification
Hint: After carrying out the repair, check that the fault has been remedied.
- Read off the diagnostic trouble codes (DTCs) by clicking on the VCT2000 symbol.
Check that the relevant diagnostic trouble code (DTC) has switched status from permanent to intermittent fault.
Also check that no diagnostic trouble codes (DTCs) have been stored in connection with identifying the damper motors. Remedy by fault-tracing the relevant diagnostic trouble code (DTC).
Has the status of the diagnostic trouble code (DTC) changed?
Yes - FAULT FOUND
No - No Fault Found
