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

DESCRIPTION

If the luggage compartment door entry unlock function does not operate, the request code may not be being transmitted from the luggage compartment door. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and door control receiver is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and electrical key antenna (outside luggage)), a luggage compartment door outer switch malfunction or wave interference.

CAUTION / NOTICE / HINT

Note


  • When using the GTS with the engine switch off to troubleshoot:

    Connect the GTS to the DLC3 and turn a courtesy light switch on and off at 1.5-second intervals until communication between the GTS and vehicle begins.

  • The entry and start system (for Entry Function) uses the CAN communication system and LIN communication system. First inspect the communication systems by following How to Proceed with Troubleshooting Click here. Troubleshoot the entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.

  • Check that there are no electrical key transmitter sub-assemblies in the vehicle.

  • Before performing the inspection, check that DTC B1242 (wireless door lock control) is not output Click here.

  • Before replacing the certification ECU (smart key ECU assembly), refer to the entry and start system (for Entry Function) precaution Click here.

  • After repair, confirm that no DTCs are output by performing the "DTC Output Confirmation Operation".

      Text in Illustration
      *a Approximately 0.3 m (0.984 ft.)

      Bring the electrical key transmitter sub-assembly near the electrical key antenna (outside luggage), and perform an entry luggage compartment open function check.

      Note

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

      Tech Tips


      • When pressing the luggage compartment door opener outer switch, hold the electrical key transmitter sub-assembly approximately 1 m (3.28 ft.) above the ground and approximately 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

      • When the electrical key transmitter sub-assembly is brought near the electrical key antenna (outside luggage), 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.

      OK
      Entry functions operate normally.

    OK

      *a 0.7 to 1.0 m (2.30 to 3.28 ft.)

      Check the following antennas in the key diagnostic mode Click here.

    2. When the electrical key transmitter sub-assembly is held at the same height as the rear bumper upper surface, align it with the center of the rear of the vehicle and check that the wireless door lock buzzer sounds.

      Tech Tips


      • Hold the electrical key transmitter sub-assembly at the same height as the rear bumper upper surface and align it with the center of the rear of the vehicle (0.7 to 1.0 m (2.30 to 3.28 ft.)). Make sure that the direction of the electrical key transmitter sub-assembly is as shown in the illustration.

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