Engine Immobiliser System (W/ Entry And Start System) -- Data List / Active Test



DATA LIST
NOTICE:
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.
HINT:
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.

    HINT:
    1. *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. *2: Engine start is permitted when it is confirmed that the steering is unlocked and there are no malfunctions in the steering lock system. If engine 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. *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. *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. *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. *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. *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. *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.

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

      With the engine switch off and the shift lever in P, perform the following procedures and check the power source mode.
      1. *1: Without depressing the brake pedal, press the engine switch and check that the power source mode changes to on (ACC).
      2. *2: While depressing the brake pedal, press the engine switch and check that the engine starts.
      3. *3: Press the engine switch and check that the power source mode changes to off.
      4. *4: Door is opened (steering lock operation starts when door is opened).
