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.

    • Normal condition: If no idling conditions are specified, neutral (N) or park (P) should be selected, 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 System (Bank 1) and Control the VVT Linear (Bank 1). 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.

  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 6 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
    • Refer to EVAP System. Refer to EVAP System
    Evaporative System Check
    (Manual Mode)    		 Perform 6 steps in order to operate EVAP key-off monitor manually 35°C (95°F) or less
