Item Check List
• The UGM is detecting that the Rear Axle Tilt Sensor does not
have a Calibrated Value in Memory.
• The UGM is detecting that the Chassis Tilt Sensor does not
have a Calibrated Value in Memory.
• The UGM is detecting that the Chassis Tilt Sensor Value is
reading greater than +/- 30°.
• Check sensor for damage or faulty wiring.
• The Chassis Tilt Sensor has an internal accelerometer dis-
agreement. Tilt Sensor will need replaced.
• The UGM is detecting that the Chassis Tilt Sensor Value is not
changing during Drive.
