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.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the engine switch on (IG).

  3. Read the Data List.
