ENTRY AND START SYSTEM All Door Entry Lock/Unlock Functions do not Operate, but Wireless Functions Operate

DESCRIPTION

When the wireless operation can be used to lock and unlock the doors, the communication line between the door control receiver and certification ECU is normal. When the entry operation does not operate, one of the following may be the cause: 1) entry cancel function is set through customization; 2) malfunction in entry and start system communication line (electrical key transmitter and vehicle); or 3) wave interference.

CAUTION / NOTICE / HINT

Note


  • Before performing the inspection, check that there are no problems related to the "CAN COMMUNICATION SYSTEM" and "LIN COMMUNICATION SYSTEM".

  • When the certification ECU is replaced, the codes must be registered.

PROCEDURE

  2. CHECK WAVE ENVIRONMENT


    1. Move the electrical key transmitter as described below and perform the operation inspection Click here.

      Tech Tips


      • When the electrical key transmitter is brought near the door outside handle or electrical key antenna, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

      • The transmitting wave of the wireless function and entry function are the same, but the wave logic is different. As a result, it is possible that only the wireless function or only the entry function is affected by wave interference.

    6. Bring the electrical key transmitter near the indoor electrical key oscillator (in center console), and perform a hybrid control system start check.

      Note

      If the key is brought within 0.2 m (0.656 ft.) of the center console, communication may not possible.

    7. Bring the electrical key transmitter near the indoor electrical key oscillator (in rear seat cushion), and perform a hybrid control system start check.

      Note

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

      Note

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

      Tech Tips

      If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
