Fault two equal
Addresses
There are several components with the same address
on the CAN bus (CAN overflow)
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.
99
CANBus OFF. A CANBus user (actuators, O2 module)
switches the CANBus to OFF mode.
9A
CAN warning level. Fault probably occurred when connecting
or disconnecting a CANBus user
Any # Overflow of CAN queue
01 Overflow of RX queue
02 Overflow of TX queue
Fault with Base Unit (LMV5), or AZL5
9B
Internal Fault
Basic Unit
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 AZL.., LMV5
Fault with Connected actuators
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.
