        *a Component without harness connected
        (Back Door Lock Assembly)        		 *b Lock
        *c Unlock - -
      2. Apply auxiliary battery voltage to the door lock motor and check the operation of the door lock motor.

        OK

        Auxiliary Battery Connection Result
        Auxiliary battery positive (+) → 1 (ACT+)
        Auxiliary battery negative (-) → 2 (ACT-)        		 Unlocks

        If the result is not as specified, replace the back door lock assembly.

    2. Check the operation of the door courtesy switch.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        2 (ACT-) - 3 (D+) Locked 10 kΩ or higher
        2 (ACT-) - 3 (D+) Unlocked Below 1 Ω

        If the result is not as specified, replace the back door lock assembly.

  2. INSPECT BACK DOOR LOCK ASSEMBLY WITH COURTESY LIGHT SWITCH (w/ Power Back Door) 
    1. Apply auxiliary battery voltage to the door lock motor and check the operation of the door lock motor.

      OK

      Battery Connection Result
      Auxiliary battery positive (+) → 2 (M+)
      Auxiliary battery negative (-) → 1 (M-)      		 Latch turns to full-latch position (rotates counterclockwise)
      Auxiliary battery positive (+) → 1 (M-)
      Auxiliary battery negative (-) → 2 (M+)      		 Latch turns to open-latch position (rotates clockwise)

      If the result is not as specified, replace the back door lock assembly with courtesy light switch.

      *a Clockwise
      *b Counterclockwise
      *c Over-latch
      *d Full-latch
      *e Half-latch
      *f Open-latch
      *g Component without harness connected
      (Back Door Lock Assembly with Courtesy Light Switch)
    2. Check the operation of the latch switch.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        3 (CLS) - 1 (E) Full-latch 10 kΩ or higher
        3 (CLS) - 1 (E) Half-latch 10 kΩ or higher
        3 (CLS) - 1 (E) Half-latch → Open-latch 10 kΩ or higher → Below 1 Ω
        3 (CLS) - 1 (E) Open-latch Below 1 Ω

        Standard Resistance

        Tester Connection Condition Specified Condition
        3 (CLS) - 1 (E) Open-latch Below 1 Ω
        3 (CLS) - 1 (E) Open-latch → Half-latch Below 1 Ω → 10 kΩ or higher
        3 (CLS) - 1 (E) Half-latch 10 kΩ or higher
        3 (CLS) - 1 (E) Full-latch 10 kΩ or higher
        3 (CLS) - 1 (E) Over-latch 10 kΩ or higher

        If the result is not as specified, replace the back door lock assembly with courtesy light switch.

    3. Check the operation of the pawl switch.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        2 (FSW) - 1 (E) Open-latch 10 kΩ or higher
        2 (FSW) - 1 (E) Open-latch → Half-latch 10 kΩ or higher → Below 1 Ω → 10 kΩ or higher
        2 (FSW) - 1 (E) Half-latch 10 kΩ or higher
        2 (FSW) - 1 (E) Half-latch → Full-latch 10 kΩ or higher → Below 1 Ω → 10 kΩ or higher
        2 (FSW) - 1 (E) Full-latch 10 kΩ or higher

        If the result is not as specified, replace the back door lock assembly with courtesy light switch.

    4. Check the operation of the back door courtesy switch.
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        4 (CTY) - 1 (E) Open-latch Below 1 Ω
        4 (CTY) - 1 (E) Half-latch Below 1 Ω
        4 (CTY) - 1 (E) Half-latch → Full-latch Below 1 Ω → 10 kΩ or higher
        4 (CTY) - 1 (E) Full-latch 10 kΩ or higher
        4 (CTY) - 1 (E) Over-latch 10 kΩ or higher
