   Result	Proceed to
   SFI system DTCs are not output	A
   SFI system crankshaft position sensor circuit DTC is output	B

Result:  2

B 

GO TO SFI SYSTEM. Refer to  DIAGNOSTIC TROUBLE CODE CHART [11/2016 - 10/2017]  Refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2017 - ] 

Result:  1

A 

See step  2

1. Connect the Techstream to the DLC3
2. Start the engine.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Stop and Start / Data List / Engine Speed.
