Faults discovered by slave nodes

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.

Control modules that use LIN communication can have integrated diagnostics exactly as the control modules on CAN. However, it is the Master node to which the slave node is connected that stores the diagnostic trouble codes for faults that the slave node discovers.

Information about discovered faults in the slave nodes is sent in the messages to the master node.

Each slave node on a LIN bus can be seen as an extension of the master node's own connections. In most cases it is also the master node that makes evaluations whether the diagnostic trouble code (DTC) can be set or not.
