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

Door Unlock Detection Switch Circuit
CIRCUIT DESCRIPTION
The door unlock detection switch is built in the door lock motor assembly. This switch is ON when the door
lock knob is in the unlock position and OFF when the lock knob is in the lock position. The ECU detects the
door lock knob conditions in this circuit. It is used as one of the operating conditions for the key confinement
prevention function.
