Ignition Switch Circuit
CIRCUIT DESCRIPTIONWhen the ignition switch is turned to the ACC position, battery positive voltage is applied to terminal ACC of the ECU. Also, if the ignition switch is turned to the ON position, battery positive voltage is applied to terminals ACC and IG of the ECU. When battery positive voltage is applied to terminal ACC of the ECU while the theft deterrent system is operating, the warning stops. Furthermore, the power supplied from terminals ACC and IG of the ECU is used as the power for the door courtesy switch and position switch, etc.
