Power Window Master Switch Input Test (2014 2015 2016)

NOTE:

Before testing, make sure the No. C16 (10 A) fuse in the under-hood fuse/relay box is OK.
Before testing, make sure the No. D11 (7.5 A), No. D19 (20 A), and No. D26 (7.5 A) fuses in the driver's under-dash fuse/relay box are OK.
Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A - Refer to: Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks (2014 2015 2016) .

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

3. 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.

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
2-1	YEL-GRN	Connect terminals No. 2 and No. 4, and terminals No. 1 and No. 3 with jumper wires.	Check driver's power window motor operation: The driver's power window should close.	Faulty driver's power window motor Poor ground (G501) An open or high resistance in the wire
2-1	YEL-GRN	Connect terminals No. 1 and No. 4, and terminals No. 2 and No. 3 with jumper wires.	Check driver's power window motor operation: The driver's power window should open.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
36	WHT	Disconnect these connectors: Front passenger's power window switch 37P connector Left rear power window switch 14P connector Right rear power window switch 14P connector Moonroof control unit/motor 14P connector	Check for continuity between terminal No. 36 and front passenger's power window switch 37P connector terminal No. 34: There should be continuity.	An open in the LIN(WINDOW) wire
			Check for continuity between terminal No. 36 and left rear power window switch 14P connector terminal No. 9: There should be continuity.	Faulty driver's under-dash fuse/relay box An open in the LIN(WINDOW) wire
			Check for continuity between terminal No. 36 and right rear power window switch 14P connector terminal No. 9: There should be continuity.	Faulty driver's under-dash fuse/relay box An open in the LIN(WINDOW) wire
			Check for continuity between terminal No. 36 and moonroof control unit/motor 14P connector terminal No. 12: There should be continuity.	An open in the LIN(WINDOW) wire
			Check for continuity to ground: There should be no continuity.	A short to ground in the LIN(WINDOW) wire

5. 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 power window master switch .

NOTE:

After replacing the power window master switch, do the resetting the power window control unit .

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
4	WHT	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. D19 (20 A) fuse in the driver's under-dash fuse/relay box An open or high resistance in the wire
26	GRN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. C16 (10 A) fuse in the under-hood fuse/relay box An open or high resistance in the wire
25	LT GRN	Vehicle ON mode	Measure the voltage to ground: There should be battery voltage.	Blown No. D26 (7.5 A) fuse in the driver's 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 (G506) An open or high resistance in the ground wire
31	BLK	In all power modes, disconnect the driver's power window motor 6P connector	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G501) An open or high resistance in the ground wire
13	PUR	Vehicle ON mode	Measure the voltage to ground: There should be battery voltage.	Faulty driver's power window motor An open or high resistance in the wire

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
17	LT GRN	Vehicle ON mode, and driver's power window moving up or down	Measure the voltage between terminals No. 17 and No. 31: 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 driver's power window motor An open or high resistance in the wire A short to ground in the wire
19	RED	Vehicle ON mode, and driver's power window moving up or down	Measure the voltage between terminals No. 19 and No. 31: 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 driver's power window motor An open or high resistance in the wire A short to ground in the wire
