S80 L6-2.9L VIN 92 B6294S2 (2004)
General
Each control module requires a number of software files in order to function. Most of these are downloaded via VIDA, but in certain cases they are
already in the system.
The files are stored in the Volvo central database and can be ordered via the replacement parts catalogue.
The exceptions are individual configurations which are not in the replacement part catalogue. These must be ordered using an action code via the
software manager in VIDA. The part numbers are given in the Technical Journal.
Extended information about files in the control modules
The following is a technical explanation of which files are in the control modules. The information is not necessary for a mechanic to be able to repair
the car. The information is presented here for those who wish to have a greater understanding of how the system functions.
The following types of software files are included:
-
Primary boot loader
-
Secondary boot loader
-
Application file
-
Signal configuration file
-
Market file (driver information module (DIM) only)
-
Language file (driver information module (DIM) only)
-
Car configuration file (central electronic module (CEM) only)
-
Security configuration file (central electronic module (CEM) only)
-
Local configuration file (central electronic module (CEM) and rear electronic module (REM) only).
Most of the control modules on the controller area network (CAN) can download software via VIDA. All control modules need an application file and a
signal configuration file to function. Not all control modules receive these two files when downloading software using VIDA.
In addition most of the control modules require a secondary boot load file to download the software to the control module.
Primary boot loader
The aim of the primary boot loader is to allow the download of software to a control module.
Secondary boot loader
The secondary boot loading file is a collection of instructions which work together with the primary boot loader to download the software package into
the control module. It then has no other function.
Application file
The application file is the software which contains the control module functions. If software is updated because of quality improvements for example, a
new application file is required.
Signal configuration file
All the control modules on the controller area network (CAN) must have the correct signal configuration file downloaded to communicate with each
other. The file specifies which signals should be transmitted, where and which signals should be read, and where they can be found. This file ensures that
all the control modules speak the same language. This means that an application file need not be modified if the controller area network (CAN)
environment in the car is modified.
An example is two S80 model cars. One car is structure week 0135, the other has a structure week after 0135. The application file for these cars is the
same, however the signal configuration files are different.
