    摘要: An engine control system includes a driver module and a diagnostics module. The driver module includes a high-side driver and a low-side driver, which selectively actuate a load. The driver module generates status signals based on detection of each of a plurality of failure modes of the high-side and low-side drivers. The diagnostics module increments a first error count for a first mode of the plurality of failure modes when the status signals indicate the driver module has detected the first mode. The diagnostics module increments a corresponding total count each time the driver module analyzes the first mode. The diagnostics module sets a fail state for a diagnostic trouble code (DTC) when the first error count for the first mode reaches a first predetermined threshold prior to the total count reaching a second predetermined threshold.

    摘要: A control system includes an input that one of receives and transmits diagnostic data including a fault identifier and a fault status of the fault identifier, and a filter module that filters said diagnostic data based on a comparison of the diagnostic data and a data array, wherein the data array includes a dependent identifier and a corresponding root cause identifier. The control system may be included with one or more of a vehicle control module and a service tool. A related method is also provided.

    摘要: A method and an apparatus for diagnosing the Ignition-Off Timer of an internal combustion engine. This invention monitors the initial operation of the Ignition-Off Timer each time it is enabled in order to detect a variety of malfunctions. The malfunctions are detected by comparing the operation of the Ignition-Off Timer to various reference values. Upon diagnosis of the Ignition-Off Timer, its condition is reported to the diagnostic management system, which determines whether and when a malfunction indicator is energized.
