ENTRY AND START SYSTEM (for Entry Function) Luggage Compartment Door Entry Unlock Function does not Operate when Key is Outside Luggage Compartment

DESCRIPTION

When the entry luggage compartment open function does not operate, one of the following may be the cause: 1) luggage compartment door opener outer switch malfunction; 2) communication malfunction with the outside electrical key oscillator (luggage compartment); 3) the main body ECU LH (cowl side junction block LH) receives the luggage compartment door opener outer switch ON signal, but is unable to send the signal to the certification ECU (smart key ECU assembly) through BEAN communication; or 5) certification ECU (smart key ECU assembly) malfunction.

    OK

  4. CHECK WAVE ENVIRONMENT


    1. A0161YVE02

      Bring the electrical key transmitter near the outside electrical key oscillator (luggage compartment), 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.

      Tech Tips


      • When the electrical key transmitter is brought near the outside electrical key oscillator (luggage compartment), 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 is normal A
      Operation check fails B

    A

    AFFECTED BY WAVE INTERFERENCE

    B

  5. PERFORM KEY DIAGNOSTIC MODE INSPECTION


    1. A0161YVE01

      Diagnostic mode inspection (outside electrical key oscillator (luggage compartment))


      1. Connect the intelligent tester to the DLC3.

      2. Turn the engine switch on (IG).

      3. Turn the intelligent tester on.

      4. Enter the following menus: Body / Entry & Start / Key Communication Check / Overhead + Luggage (outside).

      5. When the electrical key transmitter is held at the same height as the rear bumper upper surface aligning it with the center of the rear of the vehicle, check that the wireless door lock buzzer sounds.

        Tech Tips

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

        OK
        Wireless door lock buzzer sounds.

    NG
