  12. INSPECT FOR FUEL LEAK

    Tech Tips

    Using the intelligent tester to perform Active Tests allow 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. Perform Active Test.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

      3. Start the engine.

      4. Turn the intelligent tester on.

      5. Enter the following menus: Powertrain / Engine / Active Test.

      6. Perform the Active Test.
