Possible Causes

IMU module out of calibration, Loose IMU mounting screws, Strong magnetic interference near mower, Defective IMU sensor board

How to Fix / Troubleshooting

Safety first: Power OFF the mower and disconnect the battery before opening the housing.

  • Remove from interference: Move the mower away from large metal objects, underground pipes, or strong magnets. Avoid storing it near powerful speakers or motors.
  • Run calibration: If supported, use the Segway app or onboard menu to perform an IMU or compass calibration. Place the mower on a level surface and follow on‑screen instructions.
  • Inspect IMU mount: Locate the IMU board (often near the center of the main PCB or on a small daughterboard). Ensure it is firmly screwed down and not vibrating.
  • Check connectors: Reseat any ribbon cables or connectors between the IMU and main board.

Persistent E14 after calibration and mechanical checks indicates a likely IMU failure requiring replacement.
