Fault-tracing information
The Climate control module (CCM) has registered that the Seat heating module (SHM) does not respond correctly.

Corrective actions
- Check that the Seat heating module (SHM) has the correct ID for this vehicle model.
- Check that the control module is installed and connected correctly.
If no malfunction is found:
Replace the control module.

Fault-tracing information
After replacement of the Seat heating module (SHM), the control module must be calibrated.





Continue - Calibration

-------------------------------------------------

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. 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.

Verification

Hint: After carrying out the repair, check that the fault has been remedied.

- Read off the diagnostic trouble codes (DTCs) by clicking on the VCT2000 symbol.
Check that the relevant diagnostic trouble code (DTC) has switched status from permanent to intermittent fault.
Also check that no diagnostic trouble codes (DTCs) have been stored in connection with identifying the damper motors. Remedy by fault-tracing the relevant diagnostic trouble code (DTC).





Has the status of the diagnostic trouble code (DTC) changed?
