POWER MIRROR CONTROL SYSTEM (w/ Memory) Power Mirrors do not Return to Memorized Position

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


  1. CHECK CAN COMMUNICATION SYSTEM


    1. Use the GTS to check if the CAN communication system is functioning normally Click here.

      OK
      CAN communication DTCs are not output.

    NG
    OK
  2. CHECK SEAT MEMORY SWITCH FUNCTION


    1. 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
    OK
  3. CHECK POWER MIRROR CONTROL FUNCTION (REMOTE CONTROL MIRROR FUNCTION)


    1. Check the remote control mirror function Click here.

      OK
      Remote control mirror function is normal.

    NG
    OK
  4. READ VALUE USING GTS (MIRROR POSITION MEMORY)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Mirror L or Mirror R / Data List.

    5. Read the Data List according to the display on the GTS.

      *a Turn to Fully Left Position

      Turn the engine switch on (IG).

    2. Using the outer mirror switch assembly, turn the mirror surface to the fully left position.

    3. Press the M1 switch while the SET switch is being pressed.

    4. Check that the buzzer sounds for 0.5 seconds and the mirror surface position is memorized.

    5. Using the outer mirror switch assembly, turn the mirror surface to the fully right position.

    6. Press the M1 switch.

    7. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.
