Downloading Software And Replacing The Control Module

New software for the supplemental restraint system module (SRS) can be downloaded. When ordering software, the hardware and the software in the car is compared to the information in the Volvo central database. If the comparison is OK the software is downloaded to the control module.

Software can be downloaded if the comparison between the car and the Volvo central database does not correspond.

The software which is preprogrammed is:

• application software
• diagnostic software
• collision algorithm software.

The software which will be downloaded is parameter files containing:

• parameters unique to this model
• vehicle equipment level
• a signal configuration file.
