2. PERFORM ACTIVE TEST
HINT:
Using the Techstream to perform 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 ON.
(c) Enter the following menus: Body Electrical / Main Body / Active Test.
(d) Perform the Active Test by referring to the table below.
