SYSTEM DESCRIPTION
If any of the M1, M2 or M3 seat memory switches is pressed, the outer mirror control ECU (driver side) detects the seat memory switch status and sends the switch signal to the main body ECU (multiplex network body ECU) via CAN communication. The main body ECU (multiplex network body ECU) sends back reproduction signals to each outer mirror control ECU via CAN communication. When receiving the reproduction signals, each outer mirror control ECU assembly operates the vertical and horizontal mirror motors, which are built into the outer rear view mirror assembly, to adjust the mirror surface to the stored position.

CHECK MEMORY AND REACTIVATION FUNCTION
| *1 | Turn to Left Fully |
Turn the power switch on (IG).
Using the outer mirror switch assembly, turn the mirror surface to the fully left position.
Press the M1 switch while the SET switch is being pressed.
Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.
Using the outer mirror switch assembly, turn the mirror surface to the fully right position.
Press the M1 switch.
Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.
