Electrical Faults

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.
