CAN-network (Controller Area Network): Compatibility

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.

The units must "speak" the same language and must be compatible with each other. A standardized communication protocol is used for this.

Signal configuration (sfg) contains the language between the modules. If any module has a signal configuration which does not tally with other modules, this module is unable to communicate with other modules. This means that all modules must have compatible signal configuration. The signal configuration is sometimes changed as new messages are added and old ones are deleted.
