memory)
CIRCUIT DESCRIPTION
The position control ECU & switch assy memorizes the driver seat position and the outer mirror positions.
It controls each motor when the driving position memory switch is operated.
The position signals of the driving position memory switch received by the body ECU are sent to the position

CIRCUIT DESCRIPTION
The door unlock detection switch is built in the door lock motor. 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.
