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. E18 (20 A) fuse in the passenger's under-dash fuse relay box is OK.

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

2. Disconnect the front passenger's power window switch 37P 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. Reconnect the 37P connector to the power window 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, go to step 5.

Cavity	Wire	Test condition	Test: Desired result	Possible cause if desired result is not obtained
4	LT BLU	Under all conditions	Measure the voltage to ground: There should be battery voltage.	Blown No. E18 (20 A) fuse in the passenger's 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 (G505) An open or high resistance in the ground wire

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

6. Disconnect the connector from the front passenger's power window switch, 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 .

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
56	REDGRY	Vehicle ON mode, connect terminals No. 4 to No. 5 (or No. 6) and terminal No. 6 (or No. 5) to body ground with a jumper wire NOTE: if the mirror stops moving, disconnect battery power immediately.	Check the retract actuator operation: The right mirror should retract (or extend).	Faulty right retract actuator An open or high resistance in the wire
15	PNK	Vehicle ON mode, 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 (G505) or an open in the ground wire An open or high resistance in the wire
34	BLU	Disconnect these connectors: Power window master switch 37P connector Left rear power window switch 14P connector Right rear power window switch 14P 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 left rear power window switch 14P connector terminal No. 11: There should be continuity.	An open in the LIN (P/W) wire
			Check for continuity between terminal No. 34 and right rear power window switch 14P connector terminal No. 11: 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
