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

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

DESCRIPTION

When the entry operation and wireless operation of the door lock functions do not operate, a malfunction or wave interference may be occurring in either of the following: 1) the signal communication line between the door control receiver and certification ECU (smart key ECU assembly) (the line used for entry and wireless operations); or 2) the electrical key transmitter sub-assembly. If the entry lock and wireless lock operations cannot be performed, there may be electrical key transmitter sub-assembly malfunctions, wave interference or problems in the communication which is used for the entry and wireless function between the door control receiver and certification ECU (smart key ECU assembly).

CAUTION / NOTICE / HINT

Note:

  • 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. Troubleshoot the entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.

    Click here

  • 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.

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

  • The door control receiver has a constant voltage (5 V) supply circuit connected to terminal "+5".

PROCEDURE

  1. INSPECT BATTERY VOLTAGE

    1. Measure the voltage of the vehicle battery.

      Standard Voltage

      11 to 14 V

      Tip:

      It may be possible to tell whether the vehicle battery is discharged by operating the horn.

      If the voltage is below 11 V, recharge or replace the vehicle battery before proceeding to the next step.

        Note:

        Do not wrap the lead wire around a terminal, wedge it between terminals, or solder it. The terminal may be deformed or damaged, and the transmitter battery will not be able to be installed correctly.

      3. Carefully pull the lead wire out from the position shown in the illustration and install the previously removed transmitter battery.

        Tip:

        • When measuring the transmitter battery voltage, bring the electrical key transmitter sub-assembly within the lock entry operating range while operating the lock sensor of a door handle to perform the measurement.

        • Perform the measurement when the key is at room temperature.

        • The key sends voltage information to the certification ECU (smart key ECU assembly) when it is transmitting. When this voltage is 2.2 V or less the Data List item "Key Low Battery" displays "Yes".

  10. CHECK WAVE ENVIRONMENT

    1. Bring the electrical key transmitter sub-assembly that was checked first near the door control receiver and select the failed channel (the channel in which the buzzer did not sound) to recheck the key diagnostic mode.

      Click hereClick here

      Tip:

      • When the electrical key transmitter sub-assembly is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.

      • 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.

      • There may be wave interference if the vehicle is near broadcasting antennas, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc. In this case, move the vehicle to a different location and check if there is any improvement.

      • 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.
