This diagnostic indicates that a short circuit to ground condition exists on an output point. This means the output wiring or the connected load has inadvertently made contact with the protective earth ground or a grounded enclosure. The tag automatically resets to 0 when the condition is removed.
Click steps to track your progress.
Disconnect the load from the affected output terminal.
Use a multimeter to measure resistance between the output terminal and protective earth ground — expect a very high resistance (open circuit).
Visually inspect all physical wiring associated with the affected output for damaged insulation or contact with grounded components.
