Front Passenger's Power Window Switch Input Test
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
- Open and close the driver's door, then remove the front passenger's door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
- Disconnect the front passenger's power window switch 37P connector (A) from the front passenger's power window switch (B).
- 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 5.
- Reconnect the front passenger's door harness to the front passenger's door subharness.
- 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 7.
Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 12 RED Connect terminals No. 25 and No. 24 (or No. 12), and terminals No. 12 (or No. 24) and No. 37 with jumper wires Check front passenger's power window motor operation:
The front passenger's power window should open (or close).- Faulty front passenger's power window motor
- An open or high resistance in the wire
24 BLU 29 GRY Disconnect the power window master switch 37P connector and the panoramic glass roof control unit 10P connector Check for continuity between terminal No. 29 and power window master switch 37P connector terminal No. 27:
There should be continuity.An open in the UART wire Check for continuity between terminal No. 29 and the panoramic glass roof control unit 10P connector terminal No. 7:
There should be continuity.An open in the UART wire Check for continuity to ground:
There should be no continuity.A short to ground in the UART wire
- Reconnect the front passenger's power window switch connector to 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 (see FRONT PASSENGER'S POWER WINDOW SWITCH REPLACEMENT ).
NOTE: After replacing the front passenger's power window switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained 25 GRN Under all conditions Measure the voltage to ground:
There should be battery voltage.- Blown No. 1-2 (AS F/B STD) (40 A) fuse in the under-hood fuse/relay box
- Blown No. 13 (20 A) fuse in the passenger's under-dash fuse/relay box
- Faulty under-hood fuse/relay box
- Faulty passenger's under-dash fuse/relay box
- An open or high resistance in the wire
36 BLK In all ignition switch positions or all power modes, disconnect the front passenger's power window motor 6P connector Measure the voltage to ground:
There should be less than 0.2 V.- Poor ground (G405)
- An open or high resistance in the ground wire
37 BLK In all ignition switch positions or all power modes Measure the voltage to ground:
There should be less than 0.2 V.- Poor ground(G405)
- An open or high resistance in the ground wire
26 PUR Ignition switch ON (II), or power mode ON Measure the voltage to ground:
There should be at least about 10V.- Faulty front passenger's power window switch
- A short to ground in the wire
27 PNK Ignition switch ON (II) or power mode ON, and front passenger's power window switch moving up or down Measure the voltage between terminals No. 27 and No. 36:
An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).- Faulty front passenger's power window switch
- Faulty front passenger's power window motor
- An open or high resistance in the wire
- A short to ground in the wire
28 ORN Ignition switch ON (II) or power mode ON, and front passenger's power window switch moving up or down Measure the voltage between terminals No. 28 and No. 36:
An analog meter should alternate between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).- Faulty front passenger's power window switch
- Faulty front passenger's power window motor
- An open or high resistance in the wire
- A short to ground in the wire
