Faulty Identification
Faulty identification
Checking components on LIN bus
- Ignition on.
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.
If a control module is missing according to the car configuration, check that the control module is installed and correctly connected.
Check also whether any control modules are connected that are not occupied in the car configuration.
If the diagnostic trouble code (DTC) is stored together with CCM-0072, the fault can be due to several damper motor modules (DMM) having the same identity. In such cases, remedy by identifying the damper motor.
Read out which control modules/sensors are on LIN bus 1 and 2 and compare this to the car configuration. Which control modules and sensors are to be found and which alternatives can be presented in the car configuration can be read in the tables below.
Click the VCT2000 symbol to check which control module/sensor does not correspond to the car configuration.
Remedy as necessary.

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 (DTC) CCM-0070, CCM-0071 CCM-0072 or CCM-0073 has not been stored during identification of the damper motors.
These diagnostic trouble codes (DTCs) can only be stored when identifying damper motors. They mean that the identification has failed for some reason.
Remedy by correctly identifying the damper motor. Fault-trace according to the relevant information.
Has the status of the diagnostic trouble code (DTC) changed?
Yes - VERIFIED

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
