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
