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


  1. DATA LIST

    Note

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

    Tech Tips


    • Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    • When using the GTS with the vehicle engine switch off, connect the GTS to the vehicle 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 the 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.


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Body Electrical / Entry&Start, Power Source Control or Combination Meter / Data List.

    5. According to the display on the GTS, read the Data List.

      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 electric 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 engine 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).

      Other potential causes:


      • 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.
      Unmatch Code or Form Code format (incorrect or correct) / Yes or No

      Yes: Communication malfunction

      No: Communication normal

      There is an error in the data sent from the electrical key transmitter sub-assembly (if there is wave interference in the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "Unmatch Code or Form", "No Response", "ID Code Difference(Resp)" and "C Code Difference" in the Data List).

      Other potential causes:


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

      • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.
      Key Low Battery Transmitter battery depleted / Yes or No

      Yes: Transmitter battery depleted

      No: Transmitter battery not depleted

      		 The electrical key transmitter sub-assembly sends voltage information to the certification ECU (smart key ECU assembly) when it is transmitting. The certification ECU (smart key ECU assembly) displays "Yes" for the "Key Low Battery" item of the Data List when this voltage information indicates 2.1 V or less. 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).

      Other potential causes:


      • 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.
      C Code Difference Challenge code (incorrect or correct) / Yes or No

      Yes: Communication malfunction

      No: Communication normal

      The electrical key transmitter sub-assembly sends a response code in response to the challenge code from the vehicle, but the response code is incorrect (if there is wave interference in the RF band that the electrical key transmitter sub-assembly uses for transmission, "Yes" may be displayed for "Unmatch Code or Form", "No Response", "ID Code Difference[Resp]" and "C Code Difference" in the Data List).

      Other potential causes:


      • The electrical key transmitter sub-assembly or certification ECU (smart key ECU assembly) is malfunctioning.
      ID Code Difference Wireless ID code (incorrect or correct) / Yes or No

      Yes: Communication malfunction

      No: Communication normal

      The ID code registered in the vehicle and the ID code registered in the electrical key transmitter sub-assembly are different. (If a wireless ID other than those for any of the registered electrical key transmitter sub-assemblies is detected, "Yes" is displayed for "ID Code Difference" in the Data List. If a wireless signal from the electrical key transmitter sub-assembly of another vehicle is detected, "Yes" is displayed for "ID Code Difference[Resp]" 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 external noise (RF).

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

      		 When the immobiliser system does not change to the unset state, this item can be used to determine if the cause is the certification ECU.
      Different Rolling Code Rolling code (incorrect or correct) / Yes or No

      Yes: Communication malfunction

      No: Communication normal

      The rolling code registered in the vehicle and the rolling code registered in the electrical key transmitter sub-assembly are different. Other potential causes:


      • An electrical key transmitter sub-assembly switch is pressed 100 times or more in a location where the electric waves cannot reach the vehicle.
