What Internal Sensor means
The Lippert Ground Control LCD troubleshooting manual lists Internal Sensor as an internal sensor problem.
Owner-safe checks
- Stop using auto-level.
- Record the message for service.
Service-only work
- Jack motors, hall sensors, controller placement, harness repair, calibration, homing, high-current wiring, and controller replacement should follow Lippert service procedures.
