6. What is the function of the Engine Cranking
Diagnostic Mode?
 The engine cranking diagnostic mode is a
powertrain control module (PCM) strategy
which is separate from the normal operating
strategy. It allows the engine to crank in a
similar fashion as a conventional vehicle with
the fuel disabled.
