Engine Restart without the BISG or 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 seconds.

Engine restart with the BISG or the Starter Motor Intervention:

When the PCM cannot restart the engine without intervention, the restarting of the engine is controlled through the BISG or the starter motor. When an engine restart is initiated, the PCM activates the BISG at the earliest opportunity to rotate the engine. The PCM activates the BISG through the HS CAN power mode zero systems bus. Then on the first available compression the PCM operates the fuel injection to restart the engine in less than 0.36 seconds.
