Power Window Master Switch Input Test (Without Door Multiplex Control Unit)

NOTE:

Before testing, make sure the No. A2-2 (40 A) fuse in the under-hood fuse/relay box is OK.
Before testing, make sure the No. B42 (20 A), No. B43 (20 A), No. B44 (20 A), and No. B45 (20 A) fuse in the under-dash fuse/relay box are OK.

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

2. Disconnect the following 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.

9 • 11	PUR • BLK	Connect terminals No. 9 and No. 10, and terminals No. 11 and No. 6 with jumper wires	Check left rear power window motor operation: The left rear power window should open.
2 • 7	LT BLU • RED	Connect terminals No. 2 and No. 8, and terminals No. 7 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 Poor ground (G501) or an open in the ground wire An open or high resistance in the wire
2 • 7	LT BLU • RED	Connect terminals No. 7 and No. 8, and terminals No. 2 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 .
