Power Mirrors (Front Passenger's Power Window Switch) Input Test

NOTE:

Before testing, check for DTCs. If any DTCs are indicated, troubleshoot those DTCs first.
Before testing, make sure the No. B33 (20 A) fuse in the under-dash fuse/relay box is OK.

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 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
11 12	BRN YEL	Connect terminals No. 4 and No. 12 (or No. 11), and terminals No. 11 (or No. 12) and No. 3 with jumper wires.	Check the right power mirror operation: The right power mirror should move LEFT (or RIGHT).	Faulty right power mirror Poor ground (G503) or an open in the ground wire An open or high resistance in the wire
12 13	YEL LT GRN	Connect terminals No. 4 and No. 13 (or No. 12), and terminals No. 12 (or No. 13) and No. 3 with jumper wires.	Check the right power mirror operation: The right power mirror should move UP (or DOWN).	Faulty right power mirror Poor ground (G503) or an open in the ground wire An open or high resistance in the wire
15	BLU	Connect terminals No. 4 and No. 15 with a jumper wire	Check the right power mirror defogger operation: The right power mirror defogger should work (the inside lower edge becomes warm).	Faulty right power mirror defogger Poor ground (G503) or an open in the ground wire An open or high resistance in the wire

*: With moonroof

Cavity	Wire	Test Condition	Test: Desired Result	Possible Cause If Desired Result Is Not Obtained
34	LT BLU	Disconnect these connectors: Power window master switch 37P connector Moonroof control unit/motor 14P connector *	Check for continuity between terminal No. 34 and power window master switch 37P connector terminal No. 36: There should be continuity.	An open in the LIN (P/W) wire
			Check for continuity between terminal No. 34 and moonroof control unit/motor 14P connector terminal No. 12: There should be continuity.	An open in the LIN (P/W) wire
			Check for continuity to ground: There should be no continuity.	A short to ground in the LIN (P/W) wire

*: With moonroof

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 front passenger's power window switch - Refer to: FRONT PASSENGER'S POWER WINDOW SWITCH REMOVAL AND INSTALLATION, or REAR POWER WINDOW SWITCH REMOVAL AND INSTALLATION .

NOTE: After replacing the front passenger's power window 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	GRN	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. B33 (20 A) fuse in the 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 (G503) An open or high resistance in the ground wire
