Ignition Input

The ignition input is used to turn the module on. When the module is turned on, it reads the ignition key resistor and controls the outputs accordingly. When the module is turned off the ignition key resistor is not read, and the starter enable relay and fuel enable output do not allow the engine to start. When the ignition is turned off, the battery input to the PASS-Key II module draws about 1 milliamp.
