1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary / Engine Speed.

5. Start the engine.
6. Read the values displayed on the Techstream while the engine is running.

   Standard

   Correct values are displayed.

   HINT: 

   • To check the engine speed change, display the graph on the Techstream.
   • If the engine does not start, check the engine speed while cranking.
   • If the engine speed indicated on the Techstream remains at zero (0), there may be an open or short in the crankshaft position sensor circuit.

Result: 

OK
