Generator "L" Light Circuit

On models where generator is controlled by the PCM, PCM can use the "L" circuit to control generator operation during starting. If PCM is disabling the generator, scan tool will display ACTIVE, or when the disable operation of generator is active. PCM also supplies about 5 volts through the "L" circuit to generator. If generator becomes inoperative, PCM senses the fault through the "L" circuit and commands the Instrument Panel Circuit (IPC) to illuminate the VOLTS light.
