Data List / Active Test

  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 only. Do not depend solely on these values when determining whether or not a part is faulty.

    1. Warm up the engine.
    2. Turn the power switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the power switch on (IG).
    5. Turn the Techstream on.
    6. Enter the following menus: Powertrain / Engine and ECT / Data List.
    7. According to the display on the Techstream, read the Data List.

    HINT: 

    • Normal condition: If no idling conditions are specified, the shift lever should be in N or P, and the A/C switch and all accessory switches should be off.
    • *1: Excluding throttle valve opening percentage due to Idle Speed Control (ISC).
    • *2: Values are only displayed when performing the Active Tests: Control the VVT Linear (Bank1). For other Active Tests, the value will be 0.
  2. ACTIVE TEST 

    HINT: 

    Using the Techstream to perform the 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. Warm up the engine.
    2. Turn the power switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the power switch on (IG).
    5. Turn the Techstream on.
    6. Enter the following menus: Powertrain / Engine and ECT / Active Test.
    7. According to the display on the Techstream, perform the Active Test.

    • Refer to DTC P219A. Refer to DTC P219A: Bank 1 Air-Fuel Ratio Imbalance .
    Activate the Electric Water Pump Engine water pump assembly speed control 0 to 3000 RPM Test possible when either of the following condition is met:
    • Engine coolant temperature is Below 100°C (212°F)
    • Power switch on (IG)

    HINT: 

    *: While the Check the Cylinder Compression Active Test is being performed, if the speed of one cylinder is more than the other cylinders, it can be determined that the compression pressure of that cylinder is lower than the other cylinders.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG) and turn the tester on.
    3. Put the engine in inspection mode. Refer to INSPECTION MODE PROCEDURE .
    4. Start the engine and warm it up.
    5. Turn the power switch off.
    6. Turn the power switch on (IG) and turn the Techstream on.
    7. Put the engine in inspection mode. Refer to INSPECTION MODE PROCEDURE .

      HINT: 

      Do not start the engine.

    8. Enter the following menus: Powertrain / Engine and ECT / Active Test / Check the Cylinder Compression.

      HINT: 

      To display the entire Data List, press the pull down menu button next to Primary. Then select Compression.

    9. Push the snapshot button to turn the snapshot function on.

      HINT: 

      Using the snapshot function, data can be recorded during the Active Test.

    10. While the engine is not running, press the RIGHT or LEFT button to change the Check the Cylinder Compression to ON.
    11. Start the engine.
    12. Monitor the engine speed (Engine Speed of Cyl #1 to #4 and Av Engine Speed of All Cyl) displayed on the Techstream.
      NOTE:
      • When the Check the Cylinder Compression Active Test is turned ON, the engine will start.
      • If the Check the Cylinder Compression Active Test needs to be performed after it is turned ON and performed once, press the Exit button to return to the Active Test menu screen. Then perform the Check the Cylinder Compression Active Test again.
      • Use a fully-charged battery.

      HINT: 

      • At first, the Techstream display will show each cylinder's engine speed measurement to be extremely high. After the engine has started, each cylinder's engine speed measurement will change to the actual engine speed.
      • As soon as the measurements are obtained, finish the Active Test.
    13. Stop the engine, and then change Check the Cylinder Compression to OFF after the engine stops.
    14. Push the snapshot button to turn the snapshot function off.
    15. Select "Stored Data" on the Techstream screen, select the recorded data and display the data as a graph.

      HINT: 

      If the data is not displayed as a graph, the change of the values cannot be observed.

    16. Check the change in engine speed values.

      HINT: 

      As the data values of the Active Test return to their default values when engine is stopped, the engine speed value of each cylinder cannot be observed. Therefore, it is necessary to use the data recorded with the snapshot function to check the engine speed values recorded during engine running.

  3. SYSTEM CHECK 

    HINT: 

    Performing a System Check in the Utility menu enables the system, which consists of multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are set, and can detect potential malfunctions in the system.

    1. Connect the Techstream to the DLC3.
    2. Turn the power switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Utility.
    5. Perform the System Check by referring to the table below.
    Tester Display Test Part Control Range Diagnostic Note
    Evaporative System Check
    (Automatic Mode)    		 Perform 5 steps in order to operate EVAP key-off monitor automatically 35°C (95°F) or less
    • If no DTCs in Pending after performing this test, system functioning normally

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
