Meaning for the LMV5x system
Fault with Connected actuators, Base Unit (LMV5), or AZL
Basic unit has detected a ROM-CRC error
on the auxiliary actuator when checking its feedback signal
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
AZL on the AZL... when checking its feedback signal
There are several components with the same address
on the CAN bus (CAN overflow)
CAN is in bus off
CAN warning level. Fault probably occurred when connecting or
disconnecting a CAN bus user
CAN queue overrun
Overrun of RX queue
Overrun of TX queue
Air actuator has detected own fault and reported it to the basic
unit. Type of fault: See diagnostic code
CRC fault during ROM test
CRC fault during RAM test
Fault during key value check
Error code for time block overflow
Sync fault or CRC fault
Error code for main loop counter
Fault during stack test

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: Improve EMC.
4) If fault occurs constantly: Replace actuator or AZL5.
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
