Power Window Master Switch Input Test (2012 - 2013)

WARNING: This page is about a different variant/trim than selected.

NOTE: Before testing, make sure the No. B5 (7.5 A), No. B42 (20 A), No. B43 (20 A), No. B44 (20 A), and No. B45 (20 A) fuses in the under-dash fuse/relay box are OK.

1. Turn the ignition switch to LOCK (0).

2. Disconnect the power window master switch 26P connector .

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
19 14	YEL GRN	Connect terminals No. 19 (or No. 14) and No. 15, and terminals No. 14 (or No. 20) and No. 13 with jumper wires	Check driver's power window motor operation: The driver's power window should close (or open).	Faulty driver's power window motor An open or high resistance in the wire
24 25	LT BLU BRN	Connect terminals No. 24 (or No. 25) and No. 26, and terminals No. 25 (or No. 24) and No. 16 with jumper wires	Check front passenger's power window motor operation: The front passenger's power window should close (or open).	Faulty front passenger's power window motor Faulty front passenger's power window switch An open or high resistance in the wire
23 22	GRN PUR	Connect terminals No. 23 (or No. 22) and No. 21, and terminals No. 22 (or No. 23) and No. 16 with jumper wires	Check left rear power window motor operation: The left rear power window should close (or open).	Faulty left rear power window motor Faulty left rear power window switch An open or high resistance in the wire
18 17	LT BLU RED	Connect terminals No. 18 (or No. 17) and No. 20, and terminals No. 17 (or No. 18) and No. 16 with jumper wires	Check right rear power window motor operation: The right rear power window should close (or open).	Faulty right rear power window motor Faulty right rear power window switch An open or high resistance in the wire

5. Reconnect the connector to the power window master switch, 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: With driver's power window AUTO UP/DOWN function; 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
15	WHT	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. B42 (20 A) fuse in the under-dash fuse/relay box An open or high resistance in the wire
26	GRN	N Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Blown No. B44 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty power window relay An open or high resistance in the wire
21	PUR	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Blown No. B45 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty power window relay An open or high resistance in the wire
20	RED	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Blown No. B43 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty power window relay An open or high resistance in the wire
13	BLK	In all ignition switch positions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G502) An open or high resistance in the ground wire
16	BLK	Window lock switch ON	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G502) An open or high resistance in the ground wire
12	PUR	Ignition switch ON (II)	Measure the voltage to ground: There should be battery voltage.	Faulty power window master switch A short to ground in the wire
9	BRN	Ignition switch ON (II)	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G502) Faulty power window master switch An open or high resistance in the ground wire
11	PNK	Ignition switch ON (II), and power window master switch moving up or down.	Measure the voltage between terminals No. 11 and No. 13: 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
10	RED	Ignition switch ON (II), and power window master switch moving up or down.	Measure the voltage between terminals No. 10 and No. 13: An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about	Faulty driver's power window motor An open or high resistance in the wire A short to ground in the wire
