1. 1

   Test the wheel motors in 'Tools - Test - Power and Motors – Wheel motors' (shortcut 5-2-1-1). Check free-wheeling at 50% and 100% force, and block wheels to check for 0 cm/second speed.

2. 2

   Rotate the wheel by hand to check resistance, then disconnect the motor cabling and rotate again. If it is easier to rotate now, the control box may be faulty. Replace the motor if defective.

3. 3

   Inspect the cable harness and connector for damage and repair or replace if necessary.
