1. Check operation of the door lock.
   
   

   1. Using a screwdriver, push the latch in order to put the back door lock in the locked condition (full-latch position).
      

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

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → Terminal 5 Battery negative (-) → Terminal 3	Latch turns to open-latch position

      HINT:

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

2. Measure the resistance of the back door courtesy switch.
   

   Standard resistance (Courtesy switch):

   Tester Connection	Door Lock Latch Position	Specified Condition
   1 - 2	Open-latch	Below 1 Ω
   1 - 2	Half-latch	Below 1 Ω
   1 - 2	Full-latch	10 kΩ or higher
   1 - 2	Over-latch	10 kΩ or higher

   HINT:

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

   1. Using a screwdriver, push the latch in order to put the back door lock in the locked condition (full-latch position).
      

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

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → Terminal 5 Battery negative (-) → Terminal 7	Latch turns to open-latch position

      HINT:

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

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

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → Terminal 5 Battery negative (-) → Terminal 7	Close operation (Full-latch)
      Battery positive (+) → Terminal 7 Battery negative (-) → Terminal 5	Release operation (Open-latch)

      HINT:

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

2. Measure the resistance of the back door courtesy switch.
   

   Standard resistance (Courtesy switch):

   Tester Connection	Door Lock Latch Position	Specified Condition
   1 - 6	Open-latch	Below 1 Ω
   1 - 6	Half-latch	Below 1 Ω
   1 - 6	Full-latch	10 kΩ or higher
   1 - 6	Over-latch	10 kΩ or higher

   HINT:

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

3. Measure the resistance of the back door full-latch switch.
   

   Standard resistance (Full-latch switch):

   Tester Connection	Door Lock Latch Position	Specified Condition
   2 - 4	Open-latch	10 kΩ or higher
   2 - 4	Half-latch	10 kΩ or higher
   2 - 4	Full-latch	10 kΩ or higher
   2 - 4	Over-latch	Below 1 Ω

   HINT:

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

4. Measure the resistance of the back door half-latch switch.
   

   Standard resistance (Half-latch switch):

   Tester Connection	Door Lock Latch Position	Specified Condition
   3 - 4	Open-latch	Below 1 Ω
   3 - 4	Half-latch	10 kΩ or higher
   3 - 4	Full-latch	10 kΩ or higher
   3 - 4	Over-latch	10 kΩ or higher

   HINT:

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

5. Measure the resistance of the position switch.
   
   

   1. Full-latch:
      Connect the battery positive (+) lead to connector terminal 7 and the negative (-) lead to connector terminal 5.
      

      Standard resistance:

      Tester Connection	Driven Gear Position	Specified Condition
      8 - 9	Release	Below 1 Ω

      HINT:

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

   2. Over-latch:
      Connect the battery positive (+) lead to connector terminal 5 and the negative (-) lead to connector terminal 7.
      

      Standard resistance:

      Tester Connection	Driven Gear Position	Specified Condition
      8 - 9	Close	10 kΩ or higher

      HINT:

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