Data List / Active Test [08/2019 - ]

NOTE:
  • The steering lock ECU (upper steering column with switch bracket assembly) communicates with the Techstream 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 Techstream with the engine switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.
  1. DATA LIST 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Smart Key, Power Source Control, Starting Control, Combination Meter, Main Body or Engine and ECT / Data List.
    5. Read the Data List according to the display on the Techstream.

      SMART KEY

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

      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.

      HINT: 

      • *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 function is not malfunctioning. If engine start is not permitted, a steering lock ECU (upper steering column with switch bracket assembly) malfunction (relay, driver, etc.), an IGE circuit malfunction (wire harness or connector, certification ECU (smart key ECU assembly)), 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 certification ECU (smart key ECU assembly).
      • *5: This indicates the certification result of the certification codes of the certification ECU (smart key ECU assembly) and steering lock ECU (upper steering column with switch bracket assembly).

        When the steering lock ECU (upper steering column with switch bracket assembly) receives an unlock request from the certification ECU (smart key ECU assembly), confirmation of the certification ECU (smart key ECU assembly) L code is performed. If the L code matches, the steering lock ECU (upper steering column with switch bracket assembly) unlocks the steering.

      • *6: 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.
      • *7: 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 state park (P).
      • *8: Refer to the following Data List items when inspecting the actual vehicle.

        2. *2: Press the engine switch with the brake pedal released and check that the engine switch turns on (IG).
        3. *3: Press the engine switch with the brake pedal released and check that the engine starts.
        4. *4: Press the engine switch and check that the engine switch turns off.
        5. *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 engine 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 engine switch on (ACC) or on (IG), key verification is performed.
            1. The brake pedal is depressed so that the engine can be started.
            2. 30 seconds have elapsed after opening and closing a door.
            3. The engine 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 engine 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. ACTIVE TEST 

    HINT: 

    Using the Techstream 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 Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Power Source Control, Smart Key or Starting Control / Active Test.
    5. Perform Active Test according to the display on the Techstream.
