Circuit/System Description

This vehicle does not use a 12V starter motor to crank the internal combustion engine. A much more powerful 300V drive motor 1 located within the transmission is utilized to crank the engine. The 300V drive motor 1 can rotate the engine to operating speed (800 RPM) within just a few hundred milliseconds. The hybrid powertrain control module can detect a condition where the engine is cranking but does not start or has stalled.
