Rear Double Lock Position Switch LH Circuit

DESCRIPTION

The rear left side door double lock position switch is built into the rear left side door lock assembly. The switch turns on when the rear left side door double lock is set and turns off when the double lock is released.
The door opening relay is connected to the rear left side door lock assembly via terminal DLPL and rear left side door double lock set/released state signals are input to the relay.
The door opening relay applies voltage to terminal DLSR of the double lock position switch via terminal DLPL. When the switch is on (there is continuity between the switch terminals), a set state signal is input to the relay. When the switch is off (there is no continuity between the switch terminals), a release state signal is input.
The door opening relay sends rear left side door double lock set/released state signal to the body ECU using multiplex communication.

INSPECTION PROCEDURE

1. INSPECT REAR DOOR LOCK ASSEMBLY LH (DOUBLE LOCK POSITION SWITCH)

1. Remove the rear door lock assembly LH.

2. Apply battery voltage and set the door lock motor to the lock position.

   OK:

   Measurement Condition	Specified Condition
   Battery positive (+) →Terminal 2 Battery negative (-) →Terminal 1	Lock

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

   OK:

   Measurement Condition	Specified Condition
   Battery positive (+) →Terminal 4 Battery negative (-) →Terminal 3	Double Locking System is set
   Battery positive (+) →Terminal 3 Battery negative (-) →Terminal 4	Double Locking System is unset

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

   Standard resistance:

   Tester Connection	Double Lock Position	Specified Condition
   9 - 10	Set	Below 1 Ω
   9 - 10	Unset	10 kΩ or higher

NG	REPLACE REAR DOOR LOCK ASSEMBLY LH

OK

2. CHECK WIRE HARNESS (REAR DOOR LOCK ASSEMBLY LH - DOOR OPENING RELAY ASSEMBLY)

1. Disconnect the rear door lock assembly LH connector.

2. Disconnect the door opening relay assembly connector.

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

   Standard resistance:

   Tester Connection	Condition	Specified Condition
   D14-9 (DLSR) - D2-12 (DLPL)	Always	Below 1 Ω
   D14-10 (E) - Body ground	Always	Below 1 Ω

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
