Power Window Master Switch Input Test

NOTE: Before testing, troubleshoot the multiplex integrated control system first, using B-CAN System Diagnosis Test Mode A (see TROUBLESHOOTING - B-CAN SYSTEM DIAGNOSIS TEST MODE A ).
  1. Turn the ignition switch to LOCK (0).
  2. Open and close the driver's door, then remove the power window master switch panel (see POWER WINDOW MASTER SWITCH REPLACEMENT ).
  3. Disconnect the 37P connector (A) from the power window master switch (B).

  4. 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.
  5. Reconnect the connector to the power window master switch, turn the ignition switch to ON (II), 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 6.
      POWER WINDOW MASTER SWITCH INPUT TEST RESULT

      Cavity Wire Test condition Test: Desired result Possible cause if desired result is not obtained
      26 WHT Under all conditions Measure the voltage to ground: There should be battery voltage.
      • Blown No. B16 (10 A) fuse in the under-hood fuse/relay box
      • Faulty driver's under-dash fuse/relay box
      • An open or high resistance in the wire
      25 LT GRN Ignition switch ON (II) Measure the voltage to ground: There should be battery voltage.
      • Blown No. C26 (7.5 A) fuse in the driver's under-dash fuse/relay box
      • Faulty driver's under-dash fuse/relay box
      • An open or high resistance in the wire
      4 WHT Under all conditions Measure the voltage to ground: There should be battery voltage.
      • Blown No. C19 (20 A) fuse in the driver's under-dash fuse/relay box
      • Faulty driver's under-dash fuse/relay box
      • An open or high resistance in the wire
      31 BLK In all ignition switch positions Check for continuity to ground: There should be continuity.
      • Poor ground (G401)
      • An open or high resistance in the ground wire
      3 BLK In all ignition switch positions Check for continuity to ground: There should be continuity.
      • Poor ground (G402)
      • An open or high resistance in the ground wire
      13 PUR Ignition switch ON (II) Measure the voltage to ground: There should be battery voltage.
      • Faulty power window master switch
      • A short to ground in the wire
      19 RED Ignition switch ON (II), and driver's power window moving up or down Measure the voltage between terminals No. 19 and No. 3: An analog voltmeter should alternate to between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).
      • Faulty power window master switch
      • Faulty driver's power window motor
      • An open or high resistance in the wire
      • A short to ground in the wire
      17 LT GRN Ignition switch ON (II), and driver's power window moving up or down Measure the voltage between terminals No. 17 and No. 3: An analog voltmeter should alternate to between 0 V and about 5 V (a digital voltmeter should read about 2.5 V while the window moves).
      • Faulty power window master switch
      • Faulty driver's power window motor
      • An open or high resistance in the wire
      • A short to ground in the wire
  6. 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, the door multiplex control unit must be faulty, replace the power window master switch (see POWER WINDOW MASTER SWITCH REPLACEMENT  ).
      NOTE: After replacing the power window master switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT  ).
