Circuit/System Description

This vehicle does not use a 12V starter motor to crank the internal combustion engine. A much more powerful 360V motor located within the transmission is utilized to crank the engine. This motor, drive motor 1, can rotate the engine to operating speed within just a few hundred milliseconds. The hybrid/EV powertrain control module 1 can detect a condition where the engine is cranking but does not start or has stalled.
