Description Of Component / Function Activation

Self-adjustment of damper motors

This function can be used to carry out self adjustment of the limit positions for the damper motors. Self adjustment must be carried out if, after checks, one or more of the damper motors do not reach their limit positions or the climate control module is replaced. There are a number of possible reasons for a damper motor not reaching its end positions. For example, the motor or the damper has been turned manually, the voltage supply may have been cut, or a component has been replaced.

Downloading software and replacing the control module

New software can be downloaded into the climate control module.

When ordering software, the hardware and the software in the car is compared to the Volvo central database. If the comparison is OK the software is downloaded to the control module.

If the comparison between the car and Volvo central database is not OK, the database is updated with the car configuration. When this is complete the software is downloaded.

The entire climate control module must be replaced as one unit. The exceptions are the fan for the passenger compartment temperature sensor and the switches on the lower section of the dashboard environment panel.

Five customer parameters can be programmed into the climate control module. These customer parameters are stored in the control module but not in the Volvo central database. This means that the customer parameters must be reprogrammed when the hardware is replaced.

For further information about programmable customer parameters, see Diagnostic functions, Description of programmable parameters, customer adaptation.
