Meaning for the LMV5x System
Fault with Base Unit (LMV5) or Connected Components
When comparing the versions of the individual units,
the AZL5 has detected old versions
The diagnostic value is made up of the following faults or their
combinations (the individual diagnostic codes are added up in
hexadecimal format)
Software of the basic unit too old
Software of the load controller too old
Software of the AZL5 too old
Software of 1 or several actuators too old
Software of VSD module too old
Software of O2 module too old
Basic unit has detected a wrong state of the VSD module.
Corresponds to the "8x"-faults with the other CAN users
CRC error
Key error main loop counter
No feedback for max. number
Basic unit has detected a wrong stage of the O2 module
CRC error
Key error main loop counter
No feedback for max. number
Basic unit has detected a ROM-CRC fault in the VSD module
when checking its feedback signal
Basic unit has detected a ROM-CRC fault
in the O2 module when checking its feedback signal
Before replacing any units, start the system and wait
about 1 minute (until, after entering the parameter level,
the display "Parameters will be updated" disappears).
Then, reset the unit. Replace the unit only if the fault
message does not disappear. Replace the relevant
units by new versions
Replace the unit(s) called out in the diagnostic code. Be
sure that the new unit has up-to-date software.
1) If fault occurs sporadically: Reduce electrical noise.
2) If fault occurs constantly: Replace LMV5
3) 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...
4) Check each CANBus connector to ensure proper
termination (no conductors exposed on the back of the
plug)
1) If fault occurs sporadically: Reduce electrical noise.
2) If fault occurs constantly: Replace LMV5
