Damper Motor Module, Identification and Calibration.
When replacing a Damper Motor Module (DMM), it is necessary to identify the DMM before performing the calibration. It may be difficult to find the
identification process in VADIS version 2004F+.
When a DMM is replaced, perform following steps:
Before performing identification or calibration, make sure that the climate unit has normal room temperature. It is possible that heater flaps may not
go all the way to the end positions if the unit is too cold. This may result in temperature difference between left and right side.
1) Performing identification after replacing a DMM:
In VADIS version F+: Go to "Information Manager/Group 8/Diagnostic information/ Diagnostic trouble codes and associated procedures.
Select group 87, climate units, and open the DTC CCM-0071 - Damper motor, faulty position. In this page, click "continue" to proceed to the
"Identification of damper motors" page. For certain variants, a selection for the structure week must be made. The structure week of a car can be found in
VADIS under "Vehicle Communication/Group 0/General service/Reading off structure week".
2) After Identification, proceed with the calibration:
In VADIS version F+: Go to "Vehicle communication/group 8/ Climate Control Module/Checking LIN bus. Click on the VCT symbol to start calibrating
For future VADIS/VIDA versions, the identification process will be moved to "Vehicle Communication".
What is done during the identification?
The Climate Control Module (CCM) commands each DMM to move to its lower and upper end stop. The CCM counts the amount of steps the DMM
