Meaning for the LMV5x System
Fault with Connected actuators
Basic unit has detected a ROM-CRC error
on the auxiliary 3 actuator when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the air actuator when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the gas actuator when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the oil actuator when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the auxiliary 1 actuator when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the auxiliary 2 actuator when checking its feedback signal
Fault with Base Unit (LMV5), or AZL5
Basic unit has detected a ROM-CRC error
on the load controller when checking its feedback signal
Basic unit has detected a ROM-CRC error
on the AZL when checking its feedback signal
There are several components with the same address
on the CAN bus (CAN overflow)
CANBus OFF. A CANBus user (actuators, O2 module)
switches the CANBus to OFF mode.
CAN warning level. Fault probably occurred when connecting
or disconnecting a CANBus user
Overflow of CAN queue
Overflow of RX queue
Overflow of TX queue

Corrective Action
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 LMV5x...
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 actuator according
to diagnostic code.

Check to see if two actuators are addressed identically.
If so, erase the address on the incorrect actuator (hold
red button down about 10 seconds) and re-address.
