Auto Stop/Start Strategy

Engine Restart without the Starter Motor Intervention: 

The PCM  detects engine restart parameters resulting from a driver action or system request. The PCM  activates the fuel injection to allow the engine to continue to operate. This is available at a variable engine speed threshold which depends on engine type.

Engine restart with the Starter Motor Intervention: 

When the PCM  cannot restart the engine without intervention, the restarting of the engine is controlled through the starter motor. When an engine restart is initiated, the PCM  activates the starter motor through the starter relay to rotate the engine. Then on the first available compression the PCM  operates the fuel injection to restart the engine in less than 0.36 second.
