    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step. 

  2. INSPECT POWER WINDOW SWITCH (REAR RH) 
    1. Measure the resistance when the switch is operated according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION TABLE

      Tester Connection Switch Condition Specified Condition
      1 (D) - 2 (SD) UP Below 1 Ω
      3 (B) - 4 (U) Below 1 Ω
      1 (D) - 2 (SD) OFF Below 1 Ω
      4 (U) - 5 (SU) Below 1 Ω

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step. 

  4. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR RH) 
    1. Check power window regulator motor operation.
      1. Remove the power window regulator motor (See REMOVAL  ).
      2. Apply battery voltage to the motor connector according to the table below.
        NOTE: Do not apply battery voltage to any terminals except terminals 1 and 2.

        OK 

        MEASUREMENT CONDITION AND SPECIFIED CONDITION TABLE

        Measurement Condition Specified Condition
        Battery negative (-) → Terminal 1
        Battery positive (+) → Terminal 2        		 Motor gear rotates clockwise
        Battery negative (-) → Terminal 2
        Battery positive (+) → Terminal 1        		 Motor gear rotates counterclockwise

    2. Check PTC operation:
      NOTE: The work must be performed with the power window regulator and door glass installed on the vehicle.
      1. Install the power window regulator motor (See INSTALLATION  ).
      2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.
        NOTE: Match the arrow mark of the probe with the direction of the current flow.
      3. Fully close the door glass by pressing the power window UP switch. Wait for approximately 60 seconds.
      4. Continue to press the power window UP switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (Inspection of current shut-off).

        Standard: 4 to 90 seconds 

      5. 60 seconds after the previous step, press the power window DOWN switch (rear RH side).

        OK: The rear RH side window goes down. 

    NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR RH)  (See REMOVAL  )

    OK: Go to next step. 

  5. CHECK HARNESS AND CONNECTOR (MASTER SWITCH - SWITCH (REAR RH)) 
    1. Disconnect the M1 and J2 connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION TABLE

      Tester Connection Condition Specified Condition
      M1-10 (U) - J2-5 (SU) Always Below 1 Ω
      M1-18 (D) - J2-2 (SD) Always Below 1 Ω
      M1-10 (U) - Body ground Always 10 kΩ or higher
      M1-18 (D) - Body ground Always 10 kΩ or higher
