Downloading Software And Replacing The Control Module
WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.
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.
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.
When the control module is replaced, the new control module will not have any preprogrammed software.
The type of information which is downloaded is parameter files containing:
- vehicle type
- right / left hand drive
- parameters unique to this model
- whether the car has a passenger airbag or not
- a signal configuration file.
The MOST network is used for a total software reload.
