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.
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: 

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).
