Inspection Procedure

  1. CHECK OUTER REAR VIEW MIRROR ASSY LH (FROM UPPERMOST POSITION TO LOWERMOST POSITION MIRROR SENSORS VOLTAGE) 
    1. Check the mirror position sensors operation.
      1. Connect the positive lead from the voltmeter to terminal VSSR (M3-2) and the negative lead to terminal E1 (M3-8).
      2. Check that the voltage gradually changes according to the table below while the mirror moves from the uppermost position to lowermost position.

        STANDARD: 

        MIRROR POSITION SPECIFICATION

        Mirror position Lowermost --> Uppermost
        Voltage 2.8 - 5.0 Changes gradually 0 - 1.0

    1. NG: REPLACE OUTER REAR VIEW MIRROR ASSY LH 
    2. OK: GO TO NEXT STEP. 
  2. CHECK OUTER REAR VIEW MIRROR ASSY LH (FROM LEFT-MOST POSITION TO RIGHT-MOST POSITION MIRROR SENSORS VOLTAGE) 
    1. Check the mirror position sensors operation
      1. Connect the positive lead from the voltmeter to terminal HSRL (M3-7) and the negative lead to terminal E1 (M3-8).
      2. Check that the voltage gradually changes according to the table below while the mirror moves from the left-most position to right-most position.

        STANDARD: 

        MIRROR POSITION SPECIFICATION

        Mirror position Left-most --> Right-most
        Voltage 2.8 - 5.0 Changes gradually 0 - 1.0

    1. NG: REPLACE OUTER REAR VIEW MIRROR ASSY LH 
    2. OK: GO TO NEXT STEP. 
  3. CHECK WIRE HARNESS (OUTER MIRROR CONTROL ECU - OUTER REAR VIEW MIRROR LH) 
    1. Disconnect the M3 outer rear view mirror and M2 outer mirror control ECU connectors.
    2. Check the continuity between connectors.

      STANDARD: 

      CHECKING CONTINUITY REFERENCE DATA

      Symbols (Terminal No.)
      (Mirror - Mirror ECU)      		 Specified condition
      VSRL <==> VSR (M3-2 <==> M2-8) Continuity
      HSRL <==> HSRL (M3-7 <==> M2-9) Continuity
      E1 <==> E1 (M3-8 <==> M2-19) Continuity

    2. OK: REPLACE OUTER MIRROR CONTROL ECU ASSY 
  4. CHECK OUTER REAR VIEW MIRROR ASSY RH (FROM UPPERMOST POSITION TO LOWERMOST POSITION MIRROR SENSORS VOLTAGE) 
    1. Check the mirror position sensors operation.
      1. Connect the positive lead from the voltmeter to terminal VSSR (2) and the negative lead to terminal E1 (8).
      2. Check that the voltage gradually changes according to the table below while the mirror moves between the uppermost position and lowermost position

        STANDARD: 

        MIRROR POSITION SPECIFICATION

        Mirror position Lowermost --> Uppermost
        Voltage 2.8 - 5.0 Changes gradually 0-1.0

    1. NG: REPLACE OUTER REAR VIEW MIRROR ASSY RH 
    2. OK: GO TO NEXT STEP. 
  5. CHECK OUTER REAR VIEW MIRROR ASSY RH (FROM UPPERMOST POSITION TO LOWERMOST POSITION MIRROR SENSORS VOLTAGE) 
    1. Check the mirror potion sensors operation.
      1. Connect the positive lead from the voltmeter to terminal HSSR (7) and the negative lead to terminal E1 (8).
      2. Check that the voltage gradually changes according to the table below while the mirror moves between the left-most position and right-most position.

        STANDARD: 

        MIRROR POSITION SPECIFICATION

        Mirror position Left-most --> Right-most
        Voltage 0 - 1.0 Changes gradually 2.8 - 5.0
