Bad CalibrationSensor calibration values are out of range
The controller's level-sensor calibration values are outside the accepted range.
Plain-English answer
The Lippert service manual calls for controller replacement rather than an owner reset when this message is present.
What to check first
- 01
Stop automatic leveling.
- 02
Record the message and controller part number if visible.
- 03
Keep the RV safely supported using the manufacturer's normal parking procedure.
Stop and call a technician when
- Do not repeatedly recalibrate an out-of-range sensor.
- Arrange qualified controller diagnosis and replacement.
Check the exact manual
Applicability: Ground Control 3.0 LCD leveling systems. The data plate and specification letter determine which procedure is correct.

Bad Calibration is not the same as an RV that simply feels unlevel. The Ground Control 3.0 troubleshooting table treats this message as sensor calibration values outside their accepted range and directs replacement of the controller.
Confirm the exact message
Photograph the touch pad showing Bad Calibrationand the controller label. Do not substitute instructions for Auto Level Fail, Excess Angle, or Internal Sensor.
Stop automatic leveling
Park and support the RV using the manufacturer's normal procedure. Never work beneath an RV supported only by its leveling jacks.
Do not repeat zero-point calibration
Zero-point calibration is used when the coach's level reference needs adjustment. It does not repair sensor values that the controller reports as out of range.
Arrange controller diagnosis
Give the technician the message, controller part number, RV make and model, and any events that occurred immediately before the fault appeared.
