IMMOBILISER SYSTEM(w/ Entry and Start System) 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.


    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 / Data List.

    5. Read the Data List according to the display on the GTS.

      Tech Tips


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

      • *2: Engine start is permitted when it is confirmed that the steering is unlocked and the steering lock system is not malfunctioning. If engine start is not permitted, a steering lock ECU (steering lock actuator or upper bracket 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 ECM, the display changes to "Yes".

      • *4: This indicates that the engine start permission request signal (EGST) output from the ECM is being received by the ID code box (immobiliser code ECU).

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

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

        When the steering lock ECU (steering lock actuator or upper bracket 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 or upper bracket 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 engine switch is turned on (ACC) or on (IG), or an engine start operation is performed.

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

      • *9: Refer to the following Data List items when inspecting the actual vehicle.

        A001WAXE02

        With the engine switch off and the shift lever in P*5, perform the following procedures and check the power source mode.


        • *1: Without depressing the brake pedal*5 or clutch pedal*6, press the engine switch and check that the power source mode changes to on (ACC).

        • *2: While depressing the brake pedal*5 or clutch pedal*6, press the engine switch and check that the engine starts.

        • *3: Press the engine switch and check that the power source mode changes to off.

        • *4: Open a door (steering lock operation starts when a door is opened).

        • *5: for CVT

        • *6: for Manual Transaxle

  2. ACTIVE TEST

    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.


    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 / Active Test.

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