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.

Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.

Read the DATA LIST according to the display on the tester.

ECM (Cruise control):
