DIAGNOSTIC SYSTEM, METHOD, AND APPARATUS FOR A STARTING SYSTEM

摘要

Diagnosis system, method, and apparatus for a starting system are discloses herein. The method comprises receiving a run condition parameter for a vehicle, receiving a fueling system engagement parameter and an associated time threshold for the fueling system engagement parameter, and receiving an ignition command for turning an engine of the vehicle from an off state to an on state. If the run condition parameter is met, the method receives time data indicative of a time duration from reception of the ignition command to reach or substantially reach the fueling system engagement parameter, compare the time duration to the associated time threshold, and diagnose a starting system of the vehicle based on the comparison.

主权项

1. An apparatus, comprising:
a fueling system engagement circuit structured to receive a fueling system engagement parameter for a vehicle, wherein the fueling system engagement parameter defines an operating condition when a fueling system for the vehicle takes over for a starting system of the vehicle during a transition from an off state to an on state of an engine of the vehicle, and wherein the fueling system engagement parameter includes an associated time threshold; a timer circuit structured to receive time data indicative of a time duration for meeting the fueling system engagement parameter after an ignition command is received, wherein the ignition command is for turning the engine from the off state to the on state; and a diagnostic circuit structured to compare the time duration to the associated time threshold and responsive to the comparison, diagnose the starting system for the vehicle.
