      Result Proceed to
      B2311 is output A
      B2312 is output B
      B2313 is output C
      LIN communication system DTC output reoccur D
      DTC is not output E

    A: GO TO  DTC B2311  

    B: GO TO  DTC B2312  

    C: GO TO  DTC B2313  

    D: GO TO LIN COMMUNICATION SYSTEM  (See HOW TO PROCEED WITH TROUBLESHOOTING )

    E: GO TO NEXT STEP 

  2. CHECK MANUAL UP / DOWN FUNCTION 
    1. Check that the manual UP/DOWN function using the power window regulator switch can operate the driver door power window.

      OK: Manual UP/DOWN function operates normally. 

    NG: OTHER PROBLEM (See  REAR POWER WINDOW LH DOES NOT OPERATE WITH REAR POWER WINDOW SWITCH LH   ) 

    OK: GO TO NEXT STEP 

  3. READ VALUE OF INTELLIGENT TESTER OR TECHSTREAM (REAR MOTOR LH) 
    1. Use the Data List to check if the power window regulator motor is functioning properly.
      1. Intelligent tester

        RL DOOR MOTOR: 

        INTELLIGENT TESTER RL DOOR MOTOR

        Tester Display Measurement Item/Range Normal Condition Diagnostic Note
        RL P/W AUTO SW Rear power window LH remote auto UP/DOWN switch signal / ON or OFF ON: Rear power window LH remote auto UP/DOWN switch on master switch operated
        OFF: Rear power window LH switch on master switch not operated
        -
      2. Techstream

        RL-Door Motor: 

        TECHSTREAM RL DOOR MOTOR

        Tester Display Measurement Item/Range Normal Condition Diagnostic Note

        OK: Tester display changes normally when rear power window switch LH is operated. 

    NG: Go to step 4 

    OK: REPLACE REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH (for Rear LH) (See  REMOVAL   ) 

  4. CHECK HARNESS AND CONNECTOR (REAR SWITCH LH - REAR MOTOR LH) 
    1. Disconnect the N6 switch connector.
    2. Disconnect the N3 motor connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      REAR SWITCH LH - REAR MOTOR LH

      Tester Connection Condition Specified Condition
      O18-4 (AUTO)-O19-4 (AUTO) Always Below 1 Ω
      O18-4 (AUTO) or O19-4 (AUTO) - Body ground Always 10 kΩ or higher
