If the machine malfunctions, check the green Controller Diagnostic Lamp. If the lamp is ON, with ignition key switch in ON position, the electronic control unit (ECU) is functioning normally. If the lamp is blinking, the controller has detected a problem in the electrical circuit. The lamp will stop blinking and automatically reset when the key switch is turned OFF. If Controller Diagnostic Lamp is BLINKING ON and OFF : 1. ECU has detected an output with a short circuit. 2.
