Door Multiplex Control Unit Input Test

  1. Turn the ignition switch to LOCK (0).
  2. Carefully remove the power window master switch.
    NOTE: Be careful not to scratch the door trim.
  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, 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 6.
      TEST CONDITION CHART

      • Poor ground (G502)
      • An open in the wire
      16 RED Ignition switch ON (II), position 2 button pressed Measure the voltage to ground:
      There should be less than 0.2 V.
      • Poor ground (G501)
      • Faulty driving position memory switch
      • An open in the wire
      Ignition switch ON (II), position 2 button released Measure the voltage to ground:
      There should be about 5 V.
      • Faulty driving position memory switch
      • A short to ground in the wire
      17 GRY Ignition switch ON (II), position 1 button pressed Measure the voltage to ground:

      • Poor ground (G501)
      • Faulty driving position memory switch
      • An open in the wire
      Ignition switch ON (II), position 1 button released Measure the voltage to ground:
      There should be about 5 V.
      • Faulty driving position memory switch
      • A short to ground in the wire
      19 YEL Ignition switch ON (II), SET button pressed Measure the voltage to ground:
      There should be less than 0.2 V.
      • Poor ground (G501)
      • Faulty driving position memory switch
      • An open in the wire
      Ignition switch ON (II), SET button released Measure the voltage to ground:
      There should be about 5 V.
      • Faulty driving position memory switch
      • A short to ground in the wire
  6. Turn the ignition switch to LOCK (0), then disconnect the connector from the power window master switch, 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, the door multiplex control unit must be faulty; replace the power window master switch.
      NOTE: If you replace the power window master switch, reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).
