Corrective Action
1) This fault occurs when an un-addressed actuator is
connected to the CANBus. Addressing the actuator
should eliminate the fault.
2) 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 LMV5x...
3) Check each CANBus connector to ensure proper
termination (no conductors exposed on the back of the
plug)
4) If fault occurs sporadically: Reduce electrical noise.
5) If fault occurs constantly: Replace actuator according
to diagnostic code.
If fault occurs sporadically, reduce electrical noise.
If fault occurs continuously, 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: Reduce electrical noise.
4) If fault occurs constantly: Replace AZL5...
If fault occurs sporadically, reduce electrical noise.
If fault occurs constantly, replace the defective unit (see
diagnostic code) or the LMV5.
Note: The internal load controller and VSD module are
part of the LMV5.
