Corrective action
If fault occurs sporadically improve EMC. If fault occurs
continously, replace LMV5
1) Check CANBus cabling. Ensure that all cable shields
(screens) which are located in the cable sheath are
terminated correctly at each actuator, O2 module, and at
the LMV5
2) Check each CANBus Connector to ensure proper
termination (no conductors exposed on the back of the
plug)
3) If fault occurs sporadically: Improve EMC.
4) Replace AZL5...
If fault occurs constantly: Replace defective AZL5...(see
diagnostic code) or basic unit
