ENTRY AND START SYSTEM(for Start Function) DATA LIST / ACTIVE TEST

Note


  • The steering lock ECU (steering lock actuator or upper bracket assembly) communicates with the GTS through the certification ECU (smart key ECU assembly) which uses CAN communication. If the CAN communication system or certification ECU (smart key ECU assembly) is malfunctioning, Data List items may not be normal.

  • When using the GTS with the power 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. 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.

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Unmatched Vehicle-ID Key No. (incorrect or correct) Yes or No

      Yes: Communication malfunction

      No: Communication normal

      The vehicle ID registered in the vehicle and the vehicle ID registered in the electrical key transmitter sub-assembly are different (if a key from another vehicle is brought into the vehicle exterior detection area while the doors are locked, "Yes" is displayed for "Unmatched Vehicle-ID" in the Data List).

      Other potential causes:


      • An electrical key transmitter sub-assembly from a different vehicle is being used.

      • A communication error due to wave interference.

      • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.
      No Response Communication response Yes or No

      Yes: Communication malfunction

      No: Communication normal

      The vehicle IDs registered in the vehicle and electrical key transmitter sub-assembly match, but there is no response from the electrical key transmitter sub-assembly. (If the electrical key transmitter sub-assembly is not in the detection area or the transmitter battery is depleted resulting in a matching code not being detected when a lock switch or the power switch is pressed, etc., "Yes" is displayed for "No Response" in the Data List. If there is wave interference in the LF band that the vehicle uses for transmission or the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "No Response" in the Data List.)

      • An electrical key transmitter sub-assembly from a different vehicle is being used.

      • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.

      Tech Tips

      This Data List item should be checked when the electrical key transmitter sub-assembly is at room temperature (example: at -20°C (-4°F), "Yes" may be displayed even if the transmitter battery is new).

      "Yes" can be displayed only when the Data List item "No Responce" is "No".

      Tech Tips


      • *1: This indicates that there is a problem with the communication format between the key and certification ECU (smart key ECU assembly). Wave interference, key or certification ECU (smart key ECU assembly) malfunctions, a key from different vehicle being used, etc. are possible causes.

      • *2: Hybrid control system start is permitted when it is confirmed that the steering is unlocked and there are no malfunctions in the steering lock system. If hybrid control system start is not permitted, a steering lock ECU (steering lock actuator assembly) malfunction (relay, driver, etc.), an IGE circuit malfunction (wire harness or connector, ID code box (immobiliser code ECU)), or a steering lock sensor malfunction are possible causes.

      • *3: This indicates that transmission of the wake-up signal is possible ("Yes" indicates that the signal to begin verification-related LIN communication is being sent). When the steering lock motor is operating and an IGE ON signal is received (there is a steering lock operation request), or when communication is being performed between the certification ECU (smart key ECU assembly) and hybrid vehicle control ECU assembly, the display changes to "Yes".

      • *4: This indicates that the hybrid control system start permission request signal (EGST) output from the hybrid vehicle control ECU assembly is being received by the ID code box (immobiliser code ECU).

      • *5: This indicates the certification results of the certification codes of the certification ECU (smart key ECU assembly) and ID code box (immobiliser code ECU).

      • *6: This indicates the certification results of the certification codes of the ID code box (immobiliser code ECU) and steering lock ECU (steering lock actuator assembly).

        When the steering lock ECU (steering lock actuator assembly) receives an unlock request from the certification ECU (smart key ECU assembly), confirmation of the ID code box (immobiliser code ECU) L code is performed. If the L code matches, the steering lock ECU (steering lock actuator assembly) unlocks the steering. Also, if the S code verification result does not match, the steering lock will not be unlocked.

      • *7: The certification ECU (smart key ECU assembly) outputs a steering unlock request for 10 seconds after the power switch is turned on (ACC) or on (IG), or a hybrid control system start operation is performed.

      • *8: The certification ECU (smart key ECU assembly) outputs a steering lock request for 10 seconds after the power switch is turned off and any door is opened with the shift lever in P.

      • *9: Please refer to the following Data List of the actual vehicle.

      Tech Tips

      To check if the Data List display changes, get into the vehicle while carrying an electrical key transmitter sub-assembly and perform the following operations with the power switch off and the shift state park (P).

      • *1: Press the power switch with the brake pedal released and check that the power switch turns on (ACC).

      • *2: Press the power switch with the brake pedal released and check that the power switch turns on (IG).

      • *3: Press the power switch with the brake pedal released and check that the hybrid control system starts.

      • *4: Press the power switch and check that the power switch turns off.

      • *5: Open the driver side door and check that the steering locks.


      1. When the following condition is met, the unlock operation is performed.


        1. When the power switch is turned on (ACC) or on (IG) and the key and certification ECU (smart key ECU assembly) are verified, the steering is unlocked.

        2. When any of the following conditions are met with power switch on (ACC) or on (IG), key verification is performed.


          1. The brake pedal is depressed so that the hybrid control system can be started.

          2. 30 seconds have elapsed after opening and closing a door.

          3. The power switch is pressed.

      2. When the following conditions are met and the certification ECU (smart key ECU assembly) has been verified, the lock operation is performed.


        1. The power switch is off.

        2. The shift state is park (P).

        3. A door is opened or a door lock operation (door lock, wireless door lock or key-linked lock) is performed.

  2. Tech Tips

    Using the GTS to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    ACTIVE TEST


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Power Source Control or Entry&Start / Active Test.

    5. Perform Active Test according to the display on the GTS.
