SYSTEM DESCRIPTION
If either the M1 or M2 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 (driver side junction block assembly) via CAN communication. The main body ECU (driver side junction block assembly) 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.

PROCEDURE
1. |
CHECK CAN COMMUNICATION SYSTEM |
(a) Use the Techstream to check if the CAN communication system is functioning
normally (See page ).
OK:
CAN communication DTC is not output.
NG | ![]() |
GO TO CAN COMMUNICATION SYSTEM (DIAGNOSTIC TROUBLE CODE CHART) |
|
2. |
CHECK SEAT MEMORY SWITCH FUNCTION |
(a) When any seat memory switch (M1 or M2 switch) 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) |
|
3. |
CHECK POWER MIRROR CONTROL FUNCTION (ELECTRICAL REMOTE CONTROL MIRROR FUNCTION) |
(a) Check the electrical remote control mirror function (See page
).
OK:
Electrical remote control mirror function is normal.
NG | ![]() |
GO TO OTHER DIAGNOSIS PROCEDURE |

READ VALUE USING TECHSTREAM (MIRROR POSITION MEMORY) |
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Mirror L or Mirror R / Data List.
(e) Read the Data List according to the display on the Techstream.

CHECK MEMORY AND REACTIVATION FUNCTION |
(a) Turn the ignition switch ON. |
|
(b) Using the outer mirror switch assembly, turn the mirror surface to the fully left position.
(c) Press the M1 switch while the SET switch is being pressed.
(d) Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.
(e) Using the outer mirror switch assembly, turn the mirror surface to the fully right position.
(f) Press the M1 switch.
(g) Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.
