Power Window Master Switch Input Test

NOTE: Before testing, troubleshoot the multiplex integrated control unit 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), open and close the driver's door, then remove the power window master switch (see REAR POWER WINDOW SWITCH TEST )
  2. Disconnect the 37P connector (A) from the power window master switch (B)

  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 look OK, go to step 4.
  4. Reconnect the connector to the power window master switch, turn the ignition switch to ON (II), and do these input tests at the following connector
    • 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
    TROUBLESHOOT REFERENCE CHART

    Cavity Wire Test condition Test Desired result Possible cause if desired result is not obtained
    13 WHT Under all conditions Measure the voltage to ground
    There should be battery voltage
    • Blown No 15 (10 A) fuse in the under-hood fuse/relay box
    • Faulty driver's under-dash fuse/relay box
    • An open in the wire
    14 LT GRN Ignition switch ON (II) Measure the voltage to ground
    There should be battery voltage
    • Blown No 16 (7 5 A) fuse in the driver's under-dash fuse/relay box
    • Faulty driver's under-dash fuse/relay box
    • An open in the wire
    25 WHT Under all conditions Measure the voltage to ground
    There should be battery voltage
    • Blown No 24 (20 A) fuse in the driver's under-dash fuse/relay box
    • Faulty driver's under-dash fuse/relay box
    • An open in the wire
    32 BLK Under all conditions Measure the voltage to ground
    There should be less than 0 5V
    • Poor ground (G501)
    • An open in the wire
    37 BLK Under all conditions Measure the voltage to ground
    There should be less than 0 5V
    • Poor ground (G502)
    • An open in the wire
    3 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
    20 ORN Ignition switch ON (II), and driver's power window moving up or down Measure the voltage between terminals No 20 and No 37
    An analog voltmeter should read about 0 V - about 5 V - 0 V - about 5 V repeatedly (a digital voltmeter should read about 2 5V while the window moves)
    • Faulty power window master switch
    • Faulty driver's power window motor
    • An open in the wire
    • A short to ground in the wire
    22 PNK Ignition switch ON (II), and driver's power window moving up or down Measure the voltage between the terminals No 22 and No 37
    An analog voltmeter should read about 0 V - about 5 V - 0 V - about 5 V repeatedly (a digital voltmeter should read about 2 5V while the window moves)
    • Faulty power window master switch
    • Faulty driver's power window motor
    • An open in the wire
    • A short to ground in the wire
  5. Turn the ignition switch to LOCK (0), open and close the driver's door, then disconnect the 37P connector from the power window master switch again
  6. With the connector still disconnected, do these input tests at the following connector
    • 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 REAR POWER WINDOW SWITCH TEST )
    NOTE: After replacing the power window master switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT )
