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.
