Internal Fault

Internal fault

Replacing the component
The climate control module (CCM) has registered an internal fault in the damper motor module (DMM) for temperature right.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the damper motor module (DMM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the damper motor module (DMM) if the fault recurs.
Replace the damper motor module (DMM) for temperature right if the fault is permanent:

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?
