Front Passenger's Power Window Switch Input Test
NOTE:
Make sure the fuses associated with the system is OK.
If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A.

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

2.
Disconnect the front passenger's power window switch 37P connector.
Front Passenger's Power Window Switch 37P Connector (female terminals)
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 are 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.

Connect terminals No. 4 and No. 1, and terminals No. 2 and No. 3 with jumper wires.
Check front passenger's power window motor operation:
The front passenger's power window should close.
Faulty front passenger's power window motor
Poor ground (G401)
An open or high resistance in the wire
Connect terminals No. 2 and No. 1, and terminals No. 4 and No. 3 with jumper wires.
Check front passenger's power window motor operation:
The front passenger's power window should open.

Disconnect the front passenger's power window motor 6P connector
Check for continuity between terminal No. 25 and front passenger's power window motor 6P connector terminal No. 4:
There should be continuity.
An open or high resistance in the wire

LT BLU
Disconnect these connectors:
Power window master switch 37P connector
Panoramic glass roof motor-control unit 14P connector*2
Moonroof motor-control unit 14P connector*3
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 panoramic glass roof motor-control unit 14P connector terminal No. 12:
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 front power windows AUTO UP/DOWN function
*2: With panoramic glass roof
*3: 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.

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

In all power modes
Measure the voltage to ground:
There should be less than 0.2 V.

RED
Vehicle ON mode, and front passenger's power window moving up or down
Measure the voltage between terminals No. 35 and No. 3:
An analog meter should alternate between 0 V and 5 V (a digital voltmeter should read about 2.5 V while the window moves).
