POWER MIRROR CONTROL SYSTEM (w/o Memory) Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

This circuit is used for the signals from the outer mirror switch assembly.

The outer mirror switch assembly sends voltage signals to the main body ECU in accordance with how the switch is being operated (switch input signals). The main body ECU uses CAN communication to send this information to the outer mirror control ECU assembly.

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK CAN COMMUNICATION SYSTEM


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

      OK
      CAN communication DTC is not output.

    NG

    GO TO CAN COMMUNICATION SYSTEM Click here

    OK

  2. READ VALUE USING INTELLIGENT TESTER (OUTER MIRROR SWITCH ASSEMBLY)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Body / Main Body / Data List.

    5. Read the Data List according to the display on the intelligent tester.

      Main Body
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Mirror Selection SW (R) Mirror select switch signal for RH mirror / ON or OFF

      ON: Switch in R position

      OFF: Switch off or in L position

      		 -
      Mirror Selection SW (L) Mirror select switch signal for LH mirror / ON or OFF

      ON: Switch in L position

      OFF: Switch off or in R position

      		 -
      Mirror Position SW (R) Mirror adjust switch signal (right) / ON or OFF

      ON: Mirror adjust switch pressed right

      OFF: Mirror adjust switch not pressed right

      		 Check with the mirror select switch in a position other than neutral
      Mirror Position SW (L) Mirror adjust switch signal (left) / ON or OFF

      ON: Mirror adjust switch pressed left

      OFF: Mirror adjust switch not pressed left

      		 Check with the mirror select switch in a position other than neutral
      Mirror Position SW (Up) Mirror adjust switch signal (up) / ON or OFF

      ON: Mirror adjust switch pressed up

      OFF: Mirror adjust switch not pressed up

      		 Check with the mirror select switch in a position other than neutral
      Mirror Position SW (Dwn) Mirror adjust switch signal (down) / ON or OFF

      ON: Mirror adjust switch pressed down

      OFF: Mirror adjust switch not pressed down

      		 Check with the mirror select switch in a position other than neutral
      OK
      On the intelligent tester screen, ON or OFF is displayed for each item according to the table above.

    NG

    OK

  3. REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY


    1. Replace the outer mirror control ECU assembly Click here.


    NEXT

  4. CHECK POWER MIRROR CONTROL FUNCTION


    1. Check the power mirror control function Click here.

      OK
      Power mirror control function is normal.

    NG

    REPLACE MAIN BODY ECU (PASSENGER SIDE JUNCTION BLOCK ASSEMBLY) Click here

    OK

    END (OUTER MIRROR CONTROL ECU ASSEMBLY IS DEFECTIVE)

  5. INSPECT OUTER MIRROR SWITCH ASSEMBLY


    1. A01CBMVE03

      Remove the outer mirror switch assembly Click here.

    2. Turn the mirror select switch to a position other than neutral.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      I8-16 (M+) - I8-13 (E) Mirror adjust switch pressed up 95 to 105 Ω
      Mirror adjust switch pressed down 446 to 493 Ω
      Mirror adjust switch pressed left 760 to 840 Ω
      Mirror adjust switch pressed right 237 to 262 Ω
      Mirror adjust switch not pressed 10 kΩ or higher
      I8-11 (MSW) - I8-13 (E) Mirror select switch L 95 to 105 Ω
      Mirror select switch R Below 1 Ω
      Mirror select switch off 10 kΩ or higher

    NG

    REPLACE OUTER MIRROR SWITCH ASSEMBLY Click here

    OK

  6. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - OUTER MIRROR SWITCH ASSEMBLY)


    1. A01CFWRE11

      Disconnect the G48 connector from the main body ECU (passenger side junction block assembly).

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      G48-2 (MIRE) - I8-13 (E) Always Below 1 Ω
      G48-11 (MIRB) - I8-16 (M+) Always Below 1 Ω
      G48-12 (MIRS) - I8-11 (MSW) Always Below 1 Ω
      I8-13 (E) - Body ground Always 10 kΩ or higher
      I8-16 (M+) - Body ground Always 10 kΩ or higher
      I8-11 (MSW) - Body ground Always 10 kΩ or higher
