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

DTC Code DTC Name
All Door Entry Lock/Unlock Functions do not Operate, but Wireless Functions Operate

DESCRIPTION

If the entry lock and unlock functions do not operate, the entry cancel function may be set through the customize function, there may be communication problems between the electrical key transmitter sub-assembly and vehicle, or there may be wave interference.

CAUTION / NOTICE / HINT

Note:

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

  • When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

  • 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.

  • Before replacing the certification ECU (smart key ECU assembly) or electrical key transmitter sub-assembly, refer to entry and start system (for Entry Function) Precaution.

      The default setting for the entry cancel function is OFF. If the customer requests that the entry and start system functions (locking and unlocking the doors while carrying the electrical key transmitter sub-assembly, etc.) be canceled, the setting can be changed through the customize function.*

  3. CHECK WAVE ENVIRONMENT

    1. Move the electrical key transmitter sub-assembly as described below and perform the operation inspection.

      Tip:

      • When the electrical key transmitter sub-assembly is brought near the center pillar LH, center pillar RH or No. 3 indoor electrical key antenna assembly (back door), 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.

      Approximately 0.3 m (0.984 ft.)

      Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for driver door) and perform a driver door entry lock and unlock operation check.

      Note:

      If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the front door outside handle assembly (for driver door), communication may not be possible.

      Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the front door outside handle assembly (for front passenger door) and perform a driver door entry lock and unlock operation check.

      Note:

      If the electrical key transmitter sub-assembly is brought within 0.2 m (0.656 ft.) of the front door outside handle assembly (for front passenger door), communication may not be possible.

    4. B361569C01

      *a

      Approximately 0.7 m (2.30 ft.)

      Bring the electrical key transmitter sub-assembly approximately 0.3 m (0.984 ft.) from the No. 3 indoor electrical key antenna assembly (back door) and perform a back door 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 may not be possible.

    Tip:

    • If the inspection result is that the problem only occurs in certain locations or at certain 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.

    • If wave interference seems to be the likely cause of the problem, ask the customer if the problem occurs in specific locations.

    • Move the vehicle to a different location, perform the following procedure and check if the symptoms can be reproduced.

    • If a tool for checking radio waves, such as a signal strength meter, is available, move around the area while observing both the LF band (used by the vehicle antenna to form the detection area) and RF band (used by the electrical key transmitter sub-assembly for transmission) to check for locations where there is wave interference.

  4. CHECK KEY DIAGNOSTIC MODE

    1. Check the following antennas in key diagnostic mode.

    2. Select either channel 1 or channel 2 and perform the key diagnostic mode inspection for each channel.

      Tip:

      If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.
