Power Window Master Switch Input Test

NOTE:

Before testing, make sure the No. C8 (20 A), No. C9 (20 A), No. C10 (20 A), and No. C11 (20 A) fuses in the under-dash fuse/relay box are OK.
Before testing, make sure the No. D1-3 (50 A) fuse in the auxiliary under-dash fuse 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

2. Disconnect the power window master switch 24P 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 look 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
8.7	PNK.GRY	Connect terminals No. 8 and No. 5, and terminals No. 7 and No. 6 with jumper wires.	Check driver's power window motor operation:The driver's power window should close.	Faulty driver's power window motor An open or high resistance in the wire Poor ground (G401)
8.7	PNK.GRY	Connect terminals No. 7 and No. 5, and terminals No. 8 and No. 6 with jumper wires.	Check driver's power window motor operation:The driver's power window should open.

9.10	LT BLU.RED	Connect terminals No. 9 and No. 11, and terminals No. 10 and No. 6 with jumper wires	Check right rear power window motor operation:The right rear power window should close.	Faulty right rear power window switch Faulty right rear power window motor An open or high resistance in the wire Poor ground (G401)
9.10	LT BLU.RED	Connect terminals No. 10 and No. 11, and terminals No. 9 and No. 6 with jumper wires	Check right rear power window motor operation:The right rear power window should open.

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
6	BLK	Under all conditions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) An open or high resistance in the ground wire
2	BLK	Under all conditions	Measure the voltage to ground: There should be less than 0.2 V.	Poor ground (G401) An open or high resistance in the ground wire
5	WHT	Under all conditions	Measure the voltage to ground:There should be battery voltage.	Blown No. C8 (20 A) fuse in the under-dash fuse/relay box An open or high resistance in the wire

Cavity	Wire	Test condition	Test: Desired result	Possible cause If desired result is not obtained
14	GRN	Vehicle ON mode	Measure the voltage to ground:There should be battery voltage.	Blown No. C9 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty power window relay circuit An open or high resistance in the wire
