Passenger's Power Window Switch Input Test

NOTE: 

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

2. Disconnect the passenger's power window switch 37P connector .

Inspect the connector and socket terminals to be sure they are all making good contact:

With the connector still disconnected, do the following input tests:

Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
4*2 BLU*RED Connect terminals No. 4 and No. 1, and terminals No. 2 and No. 3 with jumper wires. Check passenger's power window motor operation: The passenger's power window should close.
  • Faulty passenger's power window motor
  • Poor ground (G505)
  • 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 passenger's power window motor operation: The passenger's power window should open.
25 BLK Disconnect the passenger's power window motor 6P connector Check for continuity between terminal No. 25 and passenger's power window motor 6P connector terminal No. 4: There should be continuity. 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 WHT Disconnect these connectors:
  • Power window master switch 37P connector
  • Moonroof motor-control unit 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 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

*: With moonroof

Reconnect the connector, and do the following input tests:

NOTE:  After replacing the 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
1 GRN Under all conditions Measure the voltage to ground: There should be battery voltage.
  • Blown No. B15 (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 (G505)
  • An open or high resistance in the ground wire
31 PUR Vehicle ON mode Measure the voltage to ground: There should be battery voltage.
  • Faulty passenger's power window motor
  • A short to ground in the wire
35 RED Vehicle ON mode, and 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).
  • Faulty passenger's power window motor
  • An open or high resistance in the wire
  • A short to ground in the wire
37 PNK Vehicle ON mode, and passenger's power window moving up or down Measure the voltage between terminals No. 37 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).
  • Faulty passenger's power window motor
  • An open or high resistance in the wire
  • A short to ground in the wire
