Electrical Load Signal

The ECM monitors a signal from diode module to determine electrical load caused by cooling fan, blower motor, rear defogger, stoplights or headlights. When voltage decreases below a specified value, ECM increases idle speed. As voltage increases, ECM readjusts the idle speed.
