Downloading Software And Replacing The Control Module
New software can be downloaded into the SRS (supplemental restraint system). 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 software file will contain different types of information depending on the car's date of
manufacture.
In S80s manufactured before structure week 9950 the control module is pre-loaded with the parameter settings file and only the signal configuration file
need be downloaded.
The Structure weeks can be read off using VIDA.
After structure week 9950 the S80, S60, V70 and V70 XC models have the same hardware but different software. When the control module is replaced
the new control module will not have any preprogrammed software.
The type of information which will be downloaded are parameter files containing:
-
Car type
-
Right / left hand drive
-
Parameters unique to this model
-
If the car has a passenger airbag or not
-
And a signal configuration file.
