Electrical faults

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 communication circuits in the LIN control modules cannot detect electrical faults on the wire. However the master node continuously reads back the last message it sent itself to check that it has been sent correctly over the LIN bus.

Should the master node discover that the message last read back is incorrect, for example if the signal wire has been short-circuited to voltage or ground, the master node can set the diagnostic trouble code (DTC) denoting the message has not been sent correctly.
