Lippert RR Jack fault code — Leveling system
Applies to: Ground Control LCD 4-point, Ground Control LCD 6-point
What RR Jack means
The Lippert Ground Control LCD troubleshooting manual lists RR Jack as a hall-signal, open-circuit, short-circuit, or communication problem at a specific jack.
Owner-safe checks
- Stop jack movement.
- Record the affected jack position and keep people clear of the jack area.
Service-only work
- Jack motors, hall sensors, controller placement, harness repair, calibration, homing, high-current wiring, and controller replacement should follow Lippert service procedures.
Safety boundary
Never use leveling jacks as service stands. Keep people clear of jacks and pinch points and do not service jack wiring or motors unless qualified.
