Lippert leveling system: EXCESSIVE ANGLE
Lippert documentation describes “EXCESSIVE ANGLE” separately for each model line: Ground Control LCD 4-point / 6-point (“Excessive angle reached during manual operation or an unsecured controller”); Ground Control 5th wheel OneControl (4-point / 6-point) (“Excessive angle reached during manual operation”); Ground Control TT OneControl (travel trailer) (“An unsecured sensor or excessive angle reached during manual operation”). Compare the wording for your model below.
Check your model first. The same code can mean different things on different models. Find the model number on the appliance's data label, then use the matching row below.

What you can safely check
- Stop jack movement.
- Relocate the fifth wheel only if it is safe to do so before retrying.
- Stop manual operation.
- Reset jacks to a more level state only from normal controls if safe.
- Relocate the trailer only if safe.
Stop and call a technician for
- Jack motors, hall sensors, controller placement, harness repair, calibration, homing, high-current wiring, and controller replacement should follow Lippert service procedures.
- Harness checks, fuse checks, controller placement, sensor placement, zero-point calibration, homing, jack service, and motor/controller repairs should be handled by a trained RV technician.
Never use leveling jacks as service stands. Keep people clear of jacks, pinch points, and trailer movement; do not service jack wiring, sensors, motors, or controllers unless qualified.
Operate only with people, pets, and property clear of the trailer and jacks. Do not lift the trailer fully off the ground or use the leveling system for service support.
