REAR DOOR LOCK INSPECTION

PROCEDURE

1. INSPECT REAR DOOR LOCK WITH MOTOR ASSEMBLY LH (w/o Double Locking System)

   
   
   1. 

      *a	Unlock
      *b	Lock
      *c	Component without harness connected (Rear Door Lock with Motor Assembly LH)

      Check the operation of the door lock motor.

      
      

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

         OK
         Connection Result Auxiliary battery positive (+) → Terminal 4 (L) Auxiliary battery negative (-) → Terminal 1 (UL) Locks Auxiliary battery positive (+) → Terminal 1 (UL) Auxiliary battery negative (-) → Terminal 4 (L) Unlocks

         If the result is not as specified, replace the rear door lock with motor assembly LH.

   2. Check the operation of the unlock detection switch.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 6 (LSSR) - 9 (E) Locked 10 kΩ or higher 6 (LSSR) - 9 (E) Unlocked Below 1 Ω

         If the result is not as specified, replace the rear door lock with motor assembly LH.

2. INSPECT REAR DOOR LOCK WITH MOTOR ASSEMBLY RH (w/o Double Locking System)

   
   
   1. 

      *a	Unlock
      *b	Lock
      *c	Component without harness connected (Rear Door Lock with Motor Assembly RH)

      Check the operation of the door lock motor.

      
      

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

         OK
         Connection Result Auxiliary battery positive (+) → Terminal 4 (L) Auxiliary battery negative (-) → Terminal 1 (UL) Locks Auxiliary battery positive (+) → Terminal 1 (UL) Auxiliary battery negative (-) → Terminal 4 (L) Unlocks

         If the result is not as specified, replace the rear door lock with motor assembly RH.

   2. Check the operation of the unlock detection switch.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 6 (LSSR) - 9 (E) Locked 10 kΩ or higher 6 (LSSR) - 9 (E) Unlocked Below 1 Ω

         If the result is not as specified, replace the rear door lock with motor assembly RH.

3. INSPECT REAR DOOR LOCK WITH MOTOR ASSEMBLY LH (w/ Double Locking System)

   
   
   1. 

      *a	Unlock
      *b	Lock
      *c	Component without harness connected (Rear Door Lock with Motor Assembly LH)

      Check the operation of the door lock motor and double lock motor.

      
      

      1. Apply auxiliary battery voltage and check the operation of the rear door lock motor and double lock motor.

         OK

         Connection Result Auxiliary battery positive (+) → Terminal 2 (L) Auxiliary battery negative (-) → Terminal 1 (UL) Locks Auxiliary battery positive (+) → Terminal 1 (UL) Auxiliary battery negative (-) → Terminal 2 (L) Unlocks Auxiliary battery positive (+) → Terminal 4 (DL) Auxiliary battery negative (-) → Terminal 3 (UNDL) Sets Auxiliary battery positive (+) → Terminal 3 (UNDL) Auxiliary battery negative (-) → Terminal 4 (DL) Unsets

         Tech Tips

         
         

         • Move the door lock motor to the lock position and set the double locking system. Check that the doors cannot be unlocked by operating the control cable.

         • Move the door lock motor to the lock position and unset the double locking system. Check that the doors can be unlocked by operating the control cable.

         If the result is not as specified, replace the rear door lock with motor assembly LH.

   2. Check the operation of the unlock detection switch and double lock position switch.

      
      

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

         Standard Resistance
         Tester Connection Condition Specified Condition 5 (LSSR) - 6 (E) Locked 10 kΩ or higher 5 (LSSR) - 6 (E) Unlocked Below 1 Ω 9 (DLSR) - 10 (E) Unset 10 kΩ or higher 9 (DLSR) - 10 (E) Set Below 1 Ω

         If the result is not as specified, replace the rear door lock with motor assembly LH.

4. INSPECT REAR DOOR LOCK WITH MOTOR ASSEMBLY RH (w/ Double Locking System)

   
   
   1. 

      *a	Unlock
      *b	Lock
      *c	Component without harness connected (Rear Door Lock with Motor Assembly RH)

      Check the operation of the door lock motor and double lock motor.

      
      

      1. Apply auxiliary battery voltage and check the operation of the rear door lock motor and double lock motor.

         OK

         Connection Result Auxiliary battery positive (+) → Terminal 4 (L) Auxiliary battery negative (-) → Terminal 3 (UL) Locks Auxiliary battery positive (+) → Terminal 3 (UL) Auxiliary battery negative (-) → Terminal 4 (L) Unlocks Auxiliary battery positive (+) → Terminal 2 (DL) Auxiliary battery negative (-) → Terminal 1 (UNDL) Sets Auxiliary battery positive (+) → Terminal 1 (UNDL) Auxiliary battery negative (-) → Terminal 2 (DL) Unsets
