Engine Stall

WARNING: This page is about a different variant/trim than selected.

If a stall occurs after a successful engine start, the hybrid/EV powertrain control module 1 will recognize the drop in engine RPM and command drive motor 1 to maintain engine RPM in an attempt to restart the engine. Drive motor 1 will continue to rotate the engine until the hybrid/EV powertrain control module 1 commands it to stop. The engine may be rotated for many minutes after the actual engine stall condition occurred and is typically stopped only after the hybrid/EV battery state of charge gets too low. This function may have the appearance of a running engine.
