To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.
Verify wiring between the motor temperature sensor and the module.
Measure resistance between pins 1 and 3 on motor temperature cable connector. Readings vary depending on temperature, but at room temperature (77°F/25°C), the resistance should be approximately 80k to 130k Ohms. An open circuit reading indicates a possible wire break. Replace motor.
