2. ACTIVE TEST
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) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
