Downloading Software and Replacing the Control Module

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.
