INSPECTION PROCEDURE

Note


  • When the front power window regulator motor assembly (for driver side) connector or the multiplex network master switch assembly connector is disconnected, the power window control system must be initialized Click here.

  • Since the power window control system has functions that use multiplex communication, first confirm that there is no malfunction in the multiplex communication system by inspecting the multiplex communication functions in accordance with the How to Proceed with Troubleshooting procedures Click here. Then, conduct the following inspection procedure.

PROCEDURE


  1. CHECK FUSES


    1. Remove the FR DOOR LH fuse* from the main body ECU LH (cowl side junction block LH).


      • *: for LHD

    2. Remove the ECU-IG RH and/or FR DOOR RH* fuse from the main body ECU RH (cowl side junction block RH).


      • *: for RHD

    3. Remove the MPX-B fuse from the engine room relay block No. 1.

    4. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      FR DOOR LH fuse*1 Always Below 1 Ω
      FR DOOR RH fuse*2 Always Below 1 Ω
      ECU-IG RH fuse Always Below 1 Ω
      MPX-B fuse Always Below 1 Ω

      • *1: for LHD

      • *2: for RHD


    NG

    REPLACE FUSE

    OK

  2. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (DRIVER SIDE POWER WINDOW UP/DOWN)


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the intelligent tester on.

    4. Enter the following menus: Body / Master Switch / Active Test.

    5. Perform the Active Test according to the display on the intelligent tester.

      Tester Display Test Part Control Range Diagnostic Note
      Driver Side Power Window Driver side power window UP/DOWN -
      OK
      Driver side power window operates normally.

      CAUTION:

      Be careful to avoid injuries as this test causes vehicle parts to move.

      During the Active Test, the jam protection function will not operate.

      M7-2 (GND) - Body ground Always Below 1 Ω
      for RHD
      Tester Connection Condition Specified Condition
      L17-2 (GND) - Body ground Always Below 1 Ω

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      for LHD
      Tester Connection Condition Specified Condition
      M7-10 (BDR) - M7-2 (GND) Always 11 to 14 V
      M7-20 (SIG) - M7-2 (GND) Engine switch off Below 1 V
      M7-20 (SIG) - M7-2 (GND) Engine switch on (IG) 11 to 14 V
      for RHD
      Tester Connection Condition Specified Condition
      L17-10 (BDR) - L17-2 (GND) Always 11 to 14 V
      L17-20 (SIG) - L17-2 (GND) Engine switch off Below 1 V
      L17-20 (SIG) - L17-2 (GND) Engine switch on (IG) 11 to 14 V

    2. Check power window regulator motor operation:


      1. Apply battery voltage to connector terminals 1 and 2.

        Note

        Do not apply battery voltage to any terminals except terminals 1 and 2.

      2. Check that the motor gear rotates smoothly as follows.

        OK
        for LHD
        Measurement Condition Specified Condition

        Battery positive (+) → 1

        Battery negative (-) → 2

        		 Motor gear rotates counterclockwise

        Battery positive (+) → 2

        Battery negative (-) → 1

        		 Motor gear rotates clockwise
        for RHD
        Measurement Condition Specified Condition

        Battery positive (+) → 1

        Battery negative (-) → 2

        		 Motor gear rotates clockwise
