Abstract
A system for a vehicle, includes a rockback detection module and a starter disabling module. The rockback detection module receives a crankshaft position signal from a bi-directional crankshaft sensor and selectively indicates that a crankshaft of an engine is rotating in a first direction based on the crankshaft position signal. The engine rotates in a second direction that is opposite to the first direction when the engine is running. The starter disabling module disables current to a starter motor when the crankshaft is rotating in the first direction.
