Power Window Master Switch Input Test

NOTE: The power window control unit is built into the power window master switch.

Remove the grip cover.

Disconnect the 22P connector (A) from the power window master switch.

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 .

With the connector still disconnected, make these input tests at the connector.

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 .

NOTE: Before testing, make sure the No. 1 (10 A), No. 22 (7.5 A), and No. 60 (50 A) fuse in the under-dash fuse/relay.

21	GRN	Ignition switch ON (II)	Connect the No. 20 and the No. 21 terminals, and No. 22 and No. 11 terminals momentarily with jumper wires: The left rear window should go down.	Blown No. 19 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty left rear power window motor Faulty left rear power window switch Poor ground (G501) An open in the wire
22	PUR	Ignition switch ON (II)	Connect the No. 20 and the No. 22 terminals, and No. 21 and No. 11 terminals momentarily with jumper wires: The left rear window should go up.
1 [10]	ORN	Connect the No. 3 [No. 4] and the No. 1 [No. 10] terminals, and No. 2 [No. 9] and No. 12 terminals momentarily with jumper wires	Check driver's power window motor operation: The driver's window should go up.	Blown No. 3 (20 A) fuse in the under-dash fuse/relay box Faulty under-dash fuse/relay box Faulty driver's power window motor Poor ground (G501) An open in the wire
2 [9]	BLU	Connect the No. 3 [No. 4] and the No. 2 [No. 9] terminals, and No. 1 [No. 10] and No. 12 terminals momentarily with jumper wires	Check driver's power window motor operation: The driver's window should go down.

Reconnect the 22P connector to the power window master switch. Turn the ignition switch to ON (II), and make these input tests at the connector.

If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the control unit must be faulty; replace the power window master switch.
