Ecd System -- Data List / Active Test



READ DATA LIST
HINT:
Using the intelligent tester's Data List allows switch, sensor, actuator, and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.
NOTICE:
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. Warm up the engine.

  2. Turn the engine switch OFF.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch ON (IG).

  5. Turn the intelligent tester ON.

  6. Enter the following menus: Powertrain / Engine / Data List.

  7. Read the Data List.
