Data List / Active Test

  1. READ 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.

    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Radar Cruise / Data List.
    5. Read the Data List according to the display on the Techstream.

      HINT:

      • A is OK, but B is NG → ECM failure
      • B is OK, but C is NG → DTC output or ECM failure
      • A is OK, but CRUISE main indicator light does not illuminate → Cruise main indicator light, wire harness, or ECM failure
  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 / Combination Meter / Active Test.
    5. Perform Active Test according to the display on the Techstream.

      HINT:

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