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. B15 (20 A) fuse in the 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.
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.

Vehicle ON mode, connect terminals No. 1 and No. 17, and terminals No. 19 and No. 3 with jumper wires.
Check the right power mirror operation:
The right power mirror should move LEFT.
Faulty right power mirror
Poor ground (G505) or an open in the ground wire
An open or high resistance in the wire
Vehicle ON mode, connect terminals No. 1 and No. 19, and terminals No. 17 and No. 3 with jumper wires.
Check the right power mirror operation:
The right power mirror should move RIGHT.

Connect terminals No. 1 and No. 18, and terminals No. 17 and No. 3 with jumper wires.
Check the right power mirror operation:
The right power mirror should move UP.
Faulty right power mirror
Poor ground (G505) or an open in the ground wire
An open or high resistance in the wire
Connect terminals No. 1 and No. 17, and terminals No. 18 and No. 3 with jumper wires.
Check the right power mirror operation:
The right power mirror should move DOWN.

Vehicle ON mode, connect terminals No. 1 and No. 23 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

Disconnect these connectors:
Power window master switch 37P connector
Moonroof motor-control unit 14P connector*2
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 motor-control unit 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
*1: With mirror defogger
*2: With moonroof

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

6.
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.

NOTE: After replacing the front passenger's power window switch, do the resetting the power window control unit.
