BACK DOOR LOCK INSPECTION

PROCEDURE

1. INSPECT BACK DOOR LOCK ASSEMBLY (w/o Power Back Door)

   1. 

      *a	Unlock
      *b	Lock
      *c	Component without harness connected (Back Door Lock Assembly)

      Check the operation of the door lock motor.

      1. Move the back door lock assembly to the lock position.

      2. Apply battery voltage to the door lock motor assembly and check the operation of the door lock motor.

         OK

         Measurement Condition	Specified Condition
         Battery positive (+) → 2 (ACT+) Battery negative (-) → 1 (ACT-)	Unlock

         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
         1 (ACT-) - 3 (D+)	Lock	10 kΩ or higher
         1 (ACT-) - 3 (D+)	Unlock	Below 1 Ω

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

2. INSPECT BACK DOOR LOCK ASSEMBLY (w/ Power Back Door)

   

   *a	Clockwise
   *b	Counterclockwise
   *c	Drive Gear
   *d	Over-latch
   *e	Full-latch
   *f	Half-latch
   *g	Open-latch
   *h	Component without harness connected (Back Door Lock Assembly)

   1. Apply battery voltage to the door lock motor and check the operation of the door lock motor.

      Table 1. OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → 1 (M+) Battery negative (-) → 2 (M-)	Latch turns to full-latch position (clockwise rotation)
      Battery positive (+) → 2 (M-) Battery negative (-) → 1 (M+)	Latch turns to open-latch position (counterclockwise rotation)

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

   2. Check the operation of the latch switch.

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

         Table 2. Standard Resistance (Full-latch Switch)

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

         Table 3. Standard Resistance (Selector Switch)

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

         Table 4. Standard Resistance (Back Door Courtesy Light Switch)

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

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