Mirrors: Description and Operation

Current is always applied to TERMINAL +B of the remote control mirror ECU through the ECU-B fuse.

When the Ignition SW is turned to ON or ACC position, the current flows to TERMINAL ACC of the remote control mirror ECU through the RAD NO.2fuse.

REMOTE CONTROL MIRROR OPERATION
When the Ignition SW is turned to ON or ACC position, the remote control mirror ECU operates. When the select SW of the remote control mirror SW is moved to the LH position and the operation SW is moved to left side, a signal is input from TERMINAL SWO2 of the remote control mirror ECU to TERMINAL 2 of the remote control mirror SW --> TERMINAL 12 --> TERMINAL SWI2 of the ECU.
As a result, the current to TERMINAL +B of the ECU flows from TERMINAL MHL of the ECU --> TERMINAL 8 of the remote control mirror LH --> motor --> TERMINAL 7 --> TERMINAL M+L of the ECU --> TERMINAL GND --> GROUND, rotating the motor to adjust the angle of the left side of the outer mirror (driver's).
To change the angle of the right side of the mirror, the operation SW of the remote control mirror SW is moved to the right side.
Then, a signal is input from TERMINAL SWO2 of the remote control mirror ECU --> TERMINAL 2 of the remote control mirror SW --> TERMINAL 8 --> TERMINAL SWI1 of the ECU.

As a result, the current to TERMINAL +B of the remote control mirror ECU flows from TERMINAL M+L of the ECU --> TERMINAL 7 of the remote control mirror LH --> motor --> TERMINAL 8 --> TERMINAL MHL of the ECU --> TERMINAL GND --> GROUND, causing the angle of the outer mirror (driver's) to change ON the right side.
The movement to other positions occurs similarly, so only the current flow to each motor is show:

SELECT SW RH POSITION, OPERATION SW LEFT POSITION
TERMINAL +B of the remote control mirror ECU --> TERMINAL MHR --> TERMINAL 8 of the remote control mirror motor --> TERMINAL 7 --> TERMINAL M+R of the ECU TERMINAL GND --> GROUND.

SELECT SW RH POSITION, OPERATION SW RIGHT POSITION
TERMINAL +B of the remote control mirror ECU --> TERMINAL M+R --> TERMINAL 7 of the remote control mirror motor --> TERMINAL 8 --> TERMINAL MHR of the ECU TERMINAL GND --> GROUND.

SELECT SW LH POSITION, OPERATION SW UP POSITION
TERMINAL +B of the remote control mirror ECU --> TERMINAL MVL --> TERMINAL 3 of the remote control mirror motor --> TERMINAL 7 --> TERMINAL M+L of the ECU TERMINAL GND --> GROUND.

SELECT SW LH POSITION, OPERATION SW DOWN POSITION
TERMINAL +B of the remote control mirror ECU --> TERMINAL M+L --> TERMINAL 7 of the remote control mirror motor --> TERMINAL 3 --> TERMINAL MVL of the ECU --> TERMINAL GND --> GROUND.

SELECT SW RH POSITION, OPERATION SW UP POSITION
TERMINAL +B of the remote control mirror --> TERMINAL MVR --> TERMINAL 3 of the remote control mirror motor --> TERMINAL 7 --> TERMINAL M+R of the ECU TERMINAL GND --> GROUND.

SELECT SW RH POSITION, OPERATION SW DOWN POSITION
TERMINAL +B of the remote control mirror --> TERMINAL M+R --> TERMINAL 7 of the remote control mirror motor --> TERMINAL 3 --> TERMINAL MVR of the ECU --> TERMINAL GND --> GROUND.

The number of turns of each motor (amount of movement of each part of the mirror) is detected by the position sensors and input to the ECU, making it possible to perform memory and return functions for the mirror position using the driving position memory and return SW.
