Faulty identification
Checking the diagnostic trouble codes (DTCs)
- Ignition on.
Click on the VCT2000 symbol. Check whether CCM-0070 is set together with CCM-0071. In which case, conclude this fault tracing procedure and rectify CCM-0071 first.
Do you want to exit fault-tracing?
Yes - Exit Fault-Tracing

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

Checking components on LIN bus
The climate control module (CCM) has registered that the number of control modules on LIN bus 1 or 2 does not correspond with the number of control modules occupied in the car configuration.
Read which control modules/sensors which are fitted on the LIN bus 1 and 2. Compare them with the vehicle configuration.
Check as follows
- Ignition on.
- Click on the VCT2000 symbol.
- Read which control modules/sensors which are fitted on the LIN bus 1 and 2.
- Scroll and compare the control modules/sensors with those which should be present according to the vehicle configuration.
Identify which control module/sensor is not present or which is incorrectly installed.
Check that the control module is installed and connected correctly.
If no fault is found try replacing the control module that is not identified correctly.
Check also whether any control modules are connected that are not occupied in the car configuration.
Remedy as necessary.
Continue fault-tracing with calibration. See:
1. Seat Heating Module (SHM) and Air Quality Sensor (AQS).
2. Damper motor module (DMM).

2 - Identifying the Damper Motor Module (DMM)
-------------------------------------------------
Identifying the Damper Motor Module (DMM)
- The control module must be identified after replacing the Damper Motor Module (DMM).
Note! Identification must only be carried out when replacing the Damper Motor Module (DMM).
Have any damper motors been replaced?
Yes - continued.
No - Calibrating the Climate Control Module (CCM)
-------------------------------------------------
Identifying the damper motor module (DMM), continued.
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. It is important that a battery charger is connected when identifying the damper motors.
- Ignition off.
- Reinstall the connectors, components etc.
Carry out identification as follows:
- Ignition on.
- Click on the VCT2000 symbol. Wait until identification has been carried out.
- Ignition off.

-------------------------------------------------
Calibrating the Climate Control Module (CCM)
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. To ensure that diagnostics for the Climate Control Module (CCM) have been carried out, delay for 30 seconds before reading out diagnostic trouble codes (DTCs) after calibration.
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. In the event of a fault in any of the LIN buses, diagnostic trouble codes (DTCs) CCM-0070 to CCM-0071 will be stored depending on the fault. These diagnostic trouble codes (DTCs) can only be stored in conjunction with this diagnostic function.
If any of these diagnostic trouble codes (DTCs) recur, recalibrate to check if the problem was overcome. If the diagnostic trouble code (DTC) recurs, fault-trace the relevant diagnostic trouble code (DTC).

Hint: After carrying out the repair, check that the fault has been remedied.
- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
Check that the relevant diagnostic trouble code (DTC) has switched status from permanent to intermittent fault.
Check also that diagnostic trouble code CCM-0070, CCM-0071 or CCM-0072 have not been generated in connection with an identification of damper motors.
These diagnostic trouble codes can only be generated in connection with an identification of damper motors and means that identification has failed for some reason.
Remedy by attempting to identify the damper motors again. Alternatively fault-trace the relevant diagnostic trouble codes (DTCs).
Has the status of the diagnostic trouble code (DTC) changed?
Yes - Troubleshooting procedure complete
No - Fault-tracing information
