CANbus Faults Including “ AZL not on Bus ” and “ System Test ” (continued)

Make sure the shielding of the CANbus cable is grounded properly. The shielding of
the CANbus cable is immediately under the plastic sheathing and encircles all five
conductors. The shielding on all segments of the CANbus cable must have continuity
with terminal X51.1. This can be checked with a multi ‐ meter by connecting one
probe on the AGG5.110 shielding clip attached to terminal X51.1, and the other
probe on the last actuator (or O
2
module) on the CANbus network.

If everything else checks out, and every time one of the actuators is plugged in it
immediately causes a CANbus fault, replace the appropriate actuator.
