- ACTIVE TEST
HINT:
Using the Techstream to perform Active Test 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 Test early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Test.
- Warm up the engine.
- Turn the engine switch off.
- Connect the Techstream to the DLC3.
- Turn the engine switch on (IG) position.
- Turn the Techstream on.
- Select the item "Powertrain / ECT / Active Test".
- According to the display on tester, perform the "Active Test".
