Generator PWM Circuit
The scan tool displays Gen. PWM in percentage.
The
PCM monitors the duty cycle of the generator through the PWM. As the generator load increases, the PCM can adjust
idle speed accordingly. If the PCM does not see any activity from the F circuit, the PCM commands the Instrument Panel Cluster
(IPC) to turn on the volts telltale.
