Remote control mirror switch circuit (w/ Driving position memory)
CIRCUIT DESCRIPTION
The remote control mirror switch has different levels of resistance depending on the switch position.
The body ECU senses the switch position through the resistance of the remote control mirror switch.
The body ECU sends an up/down/right/left signal to the driver door ECU and the passenger door ECU via
BEAN.
The mirror's driving position and retract position are directly controlled by the remote control mirror switch.

Driving position memory switch circuit (w/ Driving position
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
control ECU and switch assy via BEAN.
