Luggage Compartment Door Entry Unlock Function does not Operate when Key is Outside Luggage Compartment: Procedure

  1. CHECK SMART ACCESS SYSTEM WITH PUSH-BUTTON START 
    1. Check that the entry lock and unlock function can be operated at each door. Refer to OPERATION CHECK .

      OK

      entry functions operate normally.

    NG → See step   11 

    OK: Go to next step 

  2. CHECK LUGGAGE DOOR OPENER OPERATION 
    1. When the luggage compartment door opener switch is operated, check that the luggage compartment door opens. Refer to OPERATION CHECK .

      OK

      Luggage compartment door opens.

    NG → See step   12 

    OK: Go to next step 

  3. READ VALUE USING TECHSTREAM (LUGGAGE COMPARTMENT DOOR OPENER SWITCH) 
    1. Using the Techstream, read the Data List. Refer to DATA LIST / ACTIVE TEST .
      BACK DOOR

      Tester Display Measurement Item/Display Normal Condition Diagnostic Note
      Back Door Handle SW Luggage compartment door opener switch / ON or OFF ON: Luggage compartment door opener switch is pushed
      OFF: Luggage compartment door opener switch is not pushed
      -

      OK

      On the Techstream screen, item changes between ON and OFF according to above chart.

    NG → See step   9 

    OK: Go to next step 

  4. CHECK WAVE ENVIRONMENT 
    1. Bring the electrical key transmitter near the electrical key antenna (in rear bumper), and perform an entry luggage compartment open function check.

      NOTE:

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

      HINT: 

      • When the electrical key transmitter is brought near the electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
      • If the inspection result is that 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.

      OK

      Entry functions operate normally.

    NG → See step   5 

    OK → AFFECTED BY WAVE INTERFERENCE 

  5. KEY DIAGNOSTIC MODE 
    1. Diagnostic mode inspection (electrical key antenna)
      Fig 2: Identifying Electrical Key Antenna Height (Vehicle Center)
      GTY116523Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
      1. Connect the Techstream to the DLC3.
      2. Turn the power switch ON (IG).
      3. Turn the Techstream on.
      4. Enter the following menus: Body Electrical / Smart Access / Smart Communication Check /Overhead + Luggage.
      5. When the electrical key transmitter is held at the same height as the rear bumper upper surface and aligned with the center of the rear of the vehicle, check that the wireless door lock buzzer sounds.

        HINT: 

        If the buzzer sounds, it can be determined that the luggage compartment exterior transmitter is operating normally.

        OK

        Wireless door lock buzzer sounds

    NG → See step   6 

    OK → See step   15 

  6. CHECK HARNESS AND CONNECTOR (CERTIFICATION ECU - ELECTRICAL KEY ANTENNA)

    1. Disconnect the L15 ECU connector.
    2. Disconnect the R40 antenna connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance

      Tester Connection Condition Specified Condition
      L15-31 (CLG8) - R40-1 (CLG5) Always Below 1 Ω
      L15-32 (CG8B) - R40-2 (CLGB) Always Below 1 Ω
      L15-31 (CLG8) - Body ground Always 10 kΩ or higher
      L15-32 (CG8B) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  7. CHECK ELECTRICAL KEY ANTENNA (OPERATION) 
    1. Replace the electrical key antenna with a new or normally functioning one. Refer to REMOVAL .
    2. Check that the entry luggage compartment open function operates normally. Refer to OPERATION CHECK .

      OK

      Operates normally

    NG → See step   8 

    OK → END (ELECTRICAL KEY ANTENNA IS DEFECTIVE) 

  8. CHECK LUGGAGE DOOR CLOSER MOTOR (OPERATION) 
    1. Replace the luggage closer motor with a new or normally functioning one. Refer to REMOVAL .
    2. Check that the entry luggage compartment open function operates normally. Refer to OPERATION CHECK .

      OK

      Operates normally

    NG → See step   15 

    OK → END (LUGGAGE CLOSER MOTOR IS DEFECTIVE)
