CONTROL AREA NETWORK (CAN) FAULTS AND PRINCIPLES OF OPERATION
--CAN FAULT CATEGORIES--
NOTE:
CAN faults may be categorized as either "CAN Data indicating a fault" or "Missing CAN Data" and will indicate the potential problem as follows:
^
"CAN Data Indicating a Fault" is where a CAN signal is being received by a control module and contains data that is either indicating a fault
condition or is invalid because it is out of the specified range for the signal. This type of data will occur because of a specific fault with the
system from where the signal has been sent.
^
"Missing CAN Data" is where CAN signals are not being transmitted. Signals may be identified as missing from a particular system or a general
CAN bus failure may be identified. The DTC description will identify the system from which specific signals may be missing. A general CAN
bus failure can be caused by a problem in a control module, but is typically an indication of a problem with the CAN bus wiring.
