2. PERFORM ACTIVE TEST
HINT:
Using the Techstream to perform the Active Tests allows relays, VSVs and 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) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Perform the Active Test according to the display on the Techstream.
