GENERATOR FIELD SOURCE (+) PCM OUTPUT

This output from the Powertrain Control Module (PCM) regulates charging system voltage to the generator field source (+) circuit. The voltage range is 12.9 to 15.0 volts. Jeep models of previous years had used the ASD relay to apply the 12 volt + power supply to the generator field source (+) circuit.
