Diagnosis Procedure

1. Turn the power supply mode of the electric motor switch to OFF.
2. Check that the following fuse is not blown (open).

   Fuse No.	Current rating
   59	20 A

Is the fuse blown (open)? 

YES: Repair the blown (open) fuse repairing the affected circuit if a fuse blown (open).

NO: GO TO  2.

1. Disconnect front power window switch (passenger side) connector.
2. Turn the power supply mode of the electric motor switch to ON.
3. Check voltage between front power window switch (passenger side) harness connector and ground.

   (+)		(-)	Voltage
   Front power window switch (passenger side)
   Connector	Terminal
   D112	6	Ground	9 - 16 V

Is the inspection result normal? 

YES: GO TO  7.

NO: GO TO  3.

1. Turn the power supply mode of the electric motor switch to OFF.
2. Remove power window relay.
3. Check voltage between fuse block (J/B) and ground.

   (+)		(-)	Voltage
   Fuse block (J/B)
   Terminal
   Power window relay	Switch upstream side	Ground	9 - 16 V
   	Coil upstream side

Is the inspection result normal? 

YES: GO TO  4.

NO: Repair or replace harness.

Check continuity between fuse block (J/B) and front power window switch (passenger side) harness connector.

Is the inspection result normal? 

YES: GO TO  5.

NO: Repair or replace harness.

1. Disconnect BCM connector.
2. Check continuity between BCM harness connector and fuse block (J/B).

   BCM		Fuse block (J/B)		Continuity
   Connector	Terminal	Terminal
   M18	32	Power window relay	Coil downstream side	Existed

3. Check continuity between BCM harness connector and ground.

   BCM		-	Continuity
   Connector	Terminal
   M18	32	Ground	Not existed

Is the inspection result normal? 

YES: GO TO  6.

NO: Repair or replace harness.

Check power window relay.

Refer to COMPONENT INSPECTION .

Is the inspection result normal? 

YES: Replace BCM. Refer to REMOVAL AND INSTALLATION .

NO: Replace power window relay.

1. Turn the power supply mode of the electric motor switch to OFF.
2. Check continuity between front power window switch (passenger side) harness connector and ground.

   Front power window switch (passenger side)		-	Continuity
   Connector	Terminal
   D112	3	Ground	Existed
   	7

Is the inspection result normal? 

YES: INSPECTION END

NO: Repair or replace harness.

1. Turn the power supply mode of the electric motor switch to OFF.
2. Disconnect power window main switch connector and front power window switch (passenger side) connector.
3. Check continuity between power window main switch harness connector and front power window switch (passenger side) harness connector.

   Power window main switch		Front power window switch (passenger side)		Continuity
   Connector	Terminal	Connector	Terminal
   D6	5	D112	4	Existed
   	15		5

4. Check continuity between front power window switch (passenger side) harness connector and ground.

   Front power window switch (passenger side)		-	Continuity
   Connector	Terminal
   D112	4	Ground	Not existed
   	5

Is the inspection result normal? 

YES: GO TO  2.

NO: Repair or replace harness.

Check front power window switch (passenger side).

Refer to COMPONENT INSPECTION .

Is the inspection result normal? 

YES: INSPECTION END

NO: Replace front power window switch (passenger side). Refer to REMOVAL AND INSTALLATION .
