    1. Disconnect the P13 switch connector.
    2. Disconnect the P41 ECU connector.
    3. Measure the resistance of the wire harness side connectors.

      Standard Resistance

      Tester Connection Specified Condition
      P13-8 (PCT) - P41-20 (WLS1) Below 1 Ω
      P13-4 (E) - P41-29 (PWE) Below 1 Ω
      P13-3 (A) - P41-2 (AUTO) Below 1 Ω
      P13-1 (U) - P41-23 (MUP) Below 1 Ω
      P13-6 (D) - P41-25 (MDN) Below 1 Ω
      P13-8 (PCT) or P41-20 (WLS1) - Body ground 10 kΩ or higher
      P13-4 (E) or P41-29 (PWE) - Body ground 10 kΩ or higher
      P13-3 (A) or P41-2 (AUTO) - Body ground 10 kΩ or higher
      P13-1 (U) or P41-23 (MUP) - Body ground 10 kΩ or higher
      P13-6 (D) or P41-25 (MDN) - Body ground 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS AND CONNECTOR 

    OK: Go to next step 

  6. INSPECT FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY RH 
    1. Remove the motor.

    2. Inspect the operation of the power window regulator motor (for passenger side door).
      NOTE:
      • Be sure not to apply battery voltage to terminals 3 (PLS), 4 (LMT) and 5 (E) of the power window regulator motor RH connector, because it might damage the pulse sensor and the limit switch.
      • Be sure to reset the power window regulator motor (to the initial setting of the limit switch) when the power window regulator motor RH is installed to the regulator.
      1. Check that the motor operates smoothly when the battery voltage is applied to each terminal of the connector.

        OK

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

    NG → REPLACE FRONT POWER WINDOW REGULATOR MOTOR ASSEMBLY RH 

    OK: Go to next step 

  7. CHECK WIRE HARNESS (DOOR ECU FRONT RH - POWER WINDOW MOTOR)

    1. Disconnect the P43 ECU connector.
    2. Disconnect the P16 motor connector.
    3. Measure the resistance of the wire harness side connectors.

      Standard Resistance

      Tester Connection Specified Condition
      P43-3 (UP) - P16-1 (U) Below 1 Ω
      P43-2 (DN) - P16-2 (D) Below 1 Ω
      P43-3 (UP) or P16-1 (U) - Body ground 10 kΩ or higher
      P43-2 (DN) or P16-2 (D) - Body ground 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS AND CONNECTOR 

    OK → GO TO PASSENGER DOOR ECU POWER SOURCE CIRCUIT
