Data List / Active Test [08/2014 - ]

  1. DATA LIST 

    HINT: 

    Using the Techstream 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.

    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.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Pre-Collision / Data List.
    5. Enter the following menus: Body Electrical / Pre-Collision 2 / Data List.
    6. Read the Data List according to the display on the Techstream.

      HINT: 

      As the driving support ECU and seat belt control ECU have Data List for pre-collision system, be sure to check the Pre-Collision and Pre-Collision 2 Data Lists.

  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 power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Body Electrical / Pre-Collision / Active Test.
    5. Perform Active Test according to the display on the Techstream.

      HINT: 

      The power switch must be turned on (IG) to proceed with the Active Test using the Techstream.

      NOTE:
      • The seat belt motor will only operate when the tongue plate is inserted into the buckle (seat belt fastened).
      • To prevent overheating the belt motor, this test cannot be activated continuously. Operate it using at least a 30-second interval.
