Abstract
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.
Claims20
An apparatus, comprising:
- a fueling system engagement circuit structured to receive a fueling system engagement parameter for a vehicle, and an operating condition for the vehicle, wherein 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 when the operating condition meets the fueling system engagement parameter,
- a timer circuit structured to receive time data indicative of a time duration for the operating condition to meet 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 an associated time threshold for the operating condition to meet the fueling system engagement parameter after the ignition command is received, and responsive to the comparison, diagnose the starting system for the vehicle by selectively turning an indicator light on.
A method, comprising:
- receiving a run condition parameter for a vehicle;
- receiving an operating condition for the vehicle:
- receiving a fueling system engagement parameter associated with the operating condition;
- receiving an ignition command for turning an engine of the vehicle from an off state to an on state;
- determining the run condition parameter is met based on reception of vehicle operation data;
- responsive to the determination that the run condition parameter is met, receiving time data indicative of a time duration for the operating condition to meet the fueling system engagement parameter after receipt of the ignition command;
- comparing the time duration to an associated time threshold for the operating condition to meet the fueling system engagement parameter after the ignition command is received;
- and
- responsive to the comparison, diagnosing a starting system of the vehicle by selectively turning an indicator light on.
A system, comprising:
- a controller structured to:
- receive a run condition parameter for a vehicle;
- receive an operating condition for the vehicle;
- receive a fueling system engagement parameter associated with the operating condition;
- receive an ignition command for turning an engine of the vehicle from an off state to an on state;
- determine the run condition parameter is met based on reception of vehicle operation data;
- responsive to the determination that the run condition parameter is met, receive time data indicative of a time duration for the operating condition to meet the fueling system engagement parameter from reception of the ignition command;
- comparing the time duration to an associated time threshold for the operating condition to meet the fueling system engagement parameter after the ignition command is received;
- and responsive to the comparison, diagnosing a starting system of the vehicle by selectively turning an indicator light on.
