Passenger's Power Window Switch Input Test

NOTE:

Before testing, make sure the No. B15 (20 A) fuse in the under-dash fuse/relay box is OK.
Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.

1. Turn the vehicle to the OFF (LOCK) mode.

Inspect the connector and socket terminals to be sure they are all making good contact:

If the terminals are bent, loose, or corroded, repair them as necessary, and recheck the system.
If the terminals are OK, go to step 4.

With the connector still disconnected, do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, go to step 5.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
4*2	BLU*RED	Connect terminals No. 4 and No. 1, and terminals No. 2 and No. 3 with jumper wires.	Check passenger's power window motor operation: The passenger's power window should close.	Faulty passenger's power window motor Poor ground (G505) An open or high resistance in the wire
4*2	BLU*RED	Connect terminals No. 2 and No. 1, and terminals No. 4 and No. 3 with jumper wires.	Check passenger's power window motor operation: The passenger's power window should open.
25	BLK	Disconnect the passenger's power window motor 6P connector	Check for continuity between terminal No. 25 and passenger's power window motor 6P connector terminal No. 4: There should be continuity.	An open or high resistance in the wire

*: With moonroof

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
34	WHT	Disconnect these connectors: Power window master switch 37P connector Moonroof motor-control unit 14P connector *	Check for continuity between terminal No. 34 and power window master switch 37P connector terminal No. 36: There should be continuity.	An open in the LIN(P/W) wire
			Check for continuity between terminal No. 34 and moonroof motor-control unit 14P connector terminal No. 12: There should be continuity.	An open in the LIN(P/W) wire
			Check for continuity to ground: There should be no continuity.	A short to ground in the LIN(P/W) wire

*: With moonroof

Reconnect the connector, and do the following input tests:

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, replace the passenger's power window switch .

NOTE: After replacing the passenger's power window switch, do the resetting the power window control unit .

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
1	GRN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. B15 (20 A) fuse in the under-dash fuse/relay box An open or high resistance in the wire
3	BLK	In all power modes	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G505) An open or high resistance in the ground wire
31	PUR	Vehicle ON mode	Measure the voltage to ground: There should be battery voltage.	Faulty passenger's power window motor A short to ground in the wire
35	RED	Vehicle ON mode, and passenger's power window moving up or down	Measure the voltage between terminals No. 35 and No. 3: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves).	Faulty passenger's power window motor An open or high resistance in the wire A short to ground in the wire
37	PNK	Vehicle ON mode, and passenger's power window moving up or down	Measure the voltage between terminals No. 37 and No. 3: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves).	Faulty passenger's power window motor An open or high resistance in the wire A short to ground in the wire
