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


DESCRIPTION

When the luggage compartment door entry unlock function does not operate, one of the following may be the cause: 1) luggage compartment door opener outer switch malfunction; 2) communication malfunction between the outside electrical key oscillator (for luggage compartment) and certification ECU (smart key ECU assembly); 3) the main body ECU (instrument panel junction block assembly) 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 CAN communication; or 4) certification ECU (smart key ECU assembly) malfunction.

  1. Bring the electrical key transmitter near the outside electrical key oscillator (luggage compartment), and perform an entry luggage compartment open function check.

    NOTICE:
    If the key is brought within 0.2 m (0.656 ft) of the rear bumper, communication is not possible.
    HINT:
    1. When pressing the luggage compartment door opener outer switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.
    2. 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.
    3. If the operation 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.
