Rear Door RH Entry Lock and Unlock Functions do not Operate [08/2013 - ]: Procedure

  1. CHECK POWER DOOR LOCK OPERATION 
    1. When the master switch assembly door control switch is operated, check that the locked doors unlock.

      OK

      Door locks operate normally.

    NG → See step   12 

    OK: Go to next step 

  2. READ VALUE USING TECHSTREAM (TOUCH SENSOR, TRIGGER SWITCH) 
    1. Using the Techstream, read the Data List.
      SMART ACCESS

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Pr-Door Touch Sensor Passenger side rear door touch sensor / ON or OFF ON: Touch sensor touched
      OFF: Touch sensor not touched
      -
      Pr-Door Trigger Switch Passenger side rear door outside handle lock switch / ON or OFF ON: Entry lock switch pushed
      OFF: Entry lock switch not pushed
      -
      RESULT

      Result Proceed to
      Display changes according to manual operation A
      Display does not change according to manual operation B

    B → See step   5 

    A: Go to next step 

  3. CHECK WAVE ENVIRONMENT 
    1. Bring the electrical key transmitter near the passenger side rear door outside handle, and perform a passenger side rear door entry lock and unlock operation check.

      NOTE:

      If the key is brought within 0.2 m (0.656 ft.) of the door handle, communication is not possible.

      HINT: 

      • When the electrical key transmitter is brought near the passenger side rear door outside handle, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • If the operation check is normal, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
      RESULT

      Result Proceed to
      Operation check fails A
      Operation check is normal B

    B → AFFECTED BY WAVE INTERFERENCE 

    A: Go to next step 

  4. PERFORM KEY DIAGNOSTIC MODE INSPECTION 
    1. Diagnostic mode inspection (passenger side rear door electrical key oscillator).

      1. Connect the Techstream to the DLC3.
      2. Turn the engine switch on (IG).
      3. Turn the Techstream on.
      4. Enter the following menus: Body Electrical / Smart Access / Smart Communication Check / Overhead + Passenger Side Rear.
      5. When the electrical key transmitter is in the position shown in the illustration, check that the wireless door lock buzzer sounds.

        HINT: 

        If the buzzer sounds, it can be determined that the passenger side rear seat outside transmitter is operating normally.

        OK

        Wireless door lock buzzer sounds.

    NG → See step   5 

    OK → See step   13 

  5. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU [SMART KEY ECU ASSEMBLY] - DOOR ELECTRICAL KEY OSCILLATOR) 
    1. Disconnect the E30 ECU connector.

    2. Disconnect the z26 oscillator connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      E30-2 (SEL4) - z26-4 (SEL) Always Below 1 Ω
      E30-10 (CLG4) - z26-10 (CLG) Always Below 1 Ω
      E30-11 (CG4B) - z26-5 (CLGB) Always Below 1 Ω
      E30-2 (SEL4) - Body ground Always 10 kΩ or higher
      E30-10 (CLG4) - Body ground Always 10 kΩ or higher
      E30-11 (CG4B) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  6. CHECK HARNESS AND CONNECTOR (DOOR ELECTRICAL KEY OSCILLATOR - REAR DOOR OUTSIDE HANDLE) 
    1. Disconnect the z25 handle connector.

    2. Disconnect the z26 oscillator connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      z25-2 (ANT2) - z26-8 (ANT2) Always Below 1 Ω
      z25-5 (ANT1) - z26-3 (ANT1) Always Below 1 Ω
      z25-2 (ANT2) - Body ground Always 10 kΩ or higher
      z25-5 (ANT1) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step
