CCM-B10874A: Lin Bus A. System Internal Failures. Incorrect Component Installed (2012): Fault-Tracing: Calibration

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.

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:

Ignition on.
Click on the VCT2000 symbol in VIDA (Volvo scan tool). 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. If there is a fault in one of the LIN buses one or more diagnostic trouble code (DTCs), that affect the damper motors, will be stored.
