REAR POWER WINDOW SWITCH: Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK POWER SUPPLY CIRCUIT 

   Check voltage between rear power window switch connector and ground.

   Terminal				Condition	Voltage (V) (Approx.)
   (+)			(-)
   Rear power window switch connector		Terminal
   LH	D203	1	Ground	Ignition switch ON	Battery voltage
   RH	D303

   Is the measurement value within the specification? 

   YES: GO TO 2 (Rear power window switch LH)

   YES: GO TO  3 (Rear power window switch RH)

   NO: GO TO  4

2. CHECK HARNESS CONTINUITY (REAR POWER WINDOW SWITCH LH) 
   1. Turn ignition switch OFF.
   2. Disconnect main power window and door lock/unlock switch and rear power window switch LH.
   3. Check continuity between main power window and door lock/unlock switch connector and rear power window switch LH connector.

      Main power window and door lock/unlock switch connector	Terminal	Rear power window switch LH connector	Terminal	Continuity
      D7 (A)	1	D203 (B)	2	Yes
      	3		3

   4. Check continuity between main power window and door lock/unlock switch connector and ground.

      Main power window and door lock/unlock switch connector	Terminal	Ground	Continuity
      D7 (A)	1		No
      	3

      Is the inspection result normal? 

      YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

      NO: Repair or replace harness.

3. CHECK HARNESS CONTINUITY (REAR POWER WINDOW SWITCH RH) 
   1. Turn ignition switch OFF.
   2. Disconnect main power window and door lock/unlock switch and rear power window switch RH.
   3. Check continuity between main power window and door lock/unlock switch connector and rear power window switch RH connector.

      Main power window and door lock/unlock switch connector	Terminal	Rear power window switch RH connector	Terminal	Continuity
      D7 (A)	5	D303 (B)	3	Yes
      	7		2

   4. Check continuity between main power window and door lock/unlock switch connector and ground.

      Main power window and door lock/unlock switch connector	Terminal	Ground	Continuity
      D7 (A)	5		No
      	7

      Is the inspection result normal? 

      YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

      NO: Repair or replace harness.

4. CHECK HARNESS CONTINUITY 
   1. Disconnect BCM and rear power window switch.
   2. Check continuity between BCM connector and rear power window switch connector.

      BCM connector	Terminal	Rear power window switch connector		Terminal	Continuity
      M20 (A)	68	LH	D203 (B)	1	Yes
      		RH	D303 (B)

   3. Check continuity between BCM connector (A) and ground.

      BCM connector	Terminal	Ground	Continuity
      M20 (A)	68		No

      Is the inspection result normal? 

      YES: GO TO 5

      NO: Repair or replace harness.

5. CHECK REAR POWER WINDOW SWITCH 

   Check rear power window switch.

   Refer to "REAR POWER WINDOW SWITCH: COMPONENT INSPECTION ".

   Is the inspection result normal? 

   YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

   NO: Replace rear power window switch. Refer to "REMOVAL AND INSTALLATION ".
