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

DESCRIPTION

When the wireless door lock and unlock functions operate, the communication circuit between the door lock receiver assembly and certification ECU (smart key ECU assembly) is normal. When the entry lock and unlock functions do not operate, radio wave interference, a customized entry cancel function, or a communication error between the key and vehicle in the smart communication circuit, is suspected.

INSPECTION PROCEDURE

Note


  • The entry and start system (for entry function) uses a multiplex communication system (LIN communication system) and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting Click here. Troubleshoot the entry and start system (for entry function) after confirming that the communication system is functioning properly.

  • Confirm that another key is not in the cabin.

PROCEDURE


  1. CHECK POWER DOOR LOCK OPERATION


    1. When the door control switch on the master switch assembly is operated, check that the doors unlock and lock according to switch operation Click here.

      OK
      Door locks operate normally.

  3. CHECK WAVE ENVIRONMENT


    1. Move the key as described below and perform the operation inspection.

      Tech Tips


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

      • The transmitting waves of the wireless functions and entry functions are the same, but the wave logic is different. Therefore, it is possible that only the wireless functions or only the entry functions are affected by wave interference.

    2. A01NFEYE02

      Bring the key near the driver door outside handle assembly, and perform a front driver door entry lock and unlock operation check.

      Tech Tips

      When pressing the lock 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.

      Note

      If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

    3. A01NE3TE01

      Bring the key near the front passenger door outside handle assembly, and perform a front passenger door entry lock and unlock operation check.

      Tech Tips

      When pressing the lock 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.

      Note

      If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

    4. A01ND27E02

      Bring the key near the outside electrical key oscillator (for rear side), and perform an entry back door open function check.

      Tech Tips

      When pressing the lock 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.

      Note

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

      Tech Tips

      If the inspection result indicates 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.
