2. PERFORM 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.

a. Turn the ignition switch off.

b. Connect the Techstream to the DLC3.

c. Turn the ignition switch to ON and the Techstream on.

d. Enter the following menus: Body/Combination Meter/Active Test.

e. According to the display on the tester, perform the "Active Test".
