What happens when you unplug an ASD circuit?
That’s what will happen when you unplug the shorted item. Note that if this really is the ASD circuit, the relay only turns on for one second after you turn on the ignition switch. It won’t turn on again until you are cranking the engine. That means you’ll have to bypass the relay to troubleshoot the circuit.
