SYSTEM DESCRIPTION
If either the M1, M2 or M3 seat memory switch is pressed, the outer mirror control ECU assembly (driver door) 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 assembly 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.

INSPECTION PROCEDURE
Note
If the main body ECU (multiplex network body ECU) is replaced, refer to Service Bulletin.
PROCEDURE
CHECK CAN COMMUNICATION SYSTEM
Use the GTS to check if the CAN communication system is functioning normally Click here.
| OK |
|---|
| CAN communication DTCs are not output. |
| NG |
|
GO TO CAN COMMUNICATION SYSTEM (DIAGNOSTIC TROUBLE CODE CHART) Click here |

|
CHECK SEAT MEMORY SWITCH FUNCTION
When any seat memory switch (M1, M2 or M3) is pressed, check that the driver seat moves to the memorized position.
| OK |
|---|
| The driver seat moves to the memorized position. |
| NG |
|
GO TO POWER SEAT CONTROL SYSTEM (Power Seat does not Return to Memorized Position) Click here |
| OK |
|

CHECK MEMORY AND REACTIVATION FUNCTION
| *a | Turn to Fully Left Position |
Turn the engine 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.
