Front Passenger's Power Window Switch

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. 21. Turn the ignition switch to LOCK (0).
  2. 22. Remove the front passenger's door switch panel (see FRONT PASSENGER'S POWER WINDOW SWITCH REPLACEMENT ).
  3. 23. Disconnect the 37P connector from the front passenger's power window switch.

  4. 24. 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 25.
  5. 25. 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 26.
    CONTROL UNIT INPUT TEST RESULT

    Cavity  Wire  Test condition  Test: Desired result  Possible cause if desired result is not obtained 
    34 GRY Disconnect the power window master switch 37P connector and the 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 UART 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 UART wire
    Check for continuity to ground.
    There should be no continuity    		 A short to ground in the UART wire
  6. 26. Reconnect the 37P 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, go to step 27.
    CONTROL UNIT INPUT TEST RESULT

    Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
    4 GRN Under all conditions Measure the voltage to ground:
    There should be battery voltage.
    • Blown No. D18 (20 A) fuse in the passenger's under-dash fuse/relay box
    • Faulty driver's under-dash fuse/relay box
    • An open or high resistance in the wire
    3 BLK In all ignition switch positions 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
    27 BLK In all ignition switch positions 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
    29 BRN Front passenger's door lock knob switch in UNLOCK Measure the voltage to ground:
    There should be less than 0.2 V.
    • Faulty front passenger's door lock knob switch
    • Poor ground(G405)or an open in the ground wire
    • An open or high resistance in the wire
    Front passenger's door lock knob switch in LOCK Measure the voltage to ground:
    There should be about 5 V.
    • Faulty front passenger's door lock knob switch
    • A short to ground in the wire
  7. 27. If multiple failures are found on more than one control unit, replace the driver's under-dash fuse/relay box (includes the MICU).
