    摘要: A diagnostic system includes N dedicated diagnostic modules that each correspond with a respective one of multiple control systems. The N dedicated diagnostic modules each generate status signals indicating results of respective diagnostic tests. A diagnostic error time monitor determines an accumulated error time value between error events for each of the control systems based on the status signals. The diagnostic error time monitor selectively reports a fault to a respective one of the N dedicated diagnostic modules based on the accumulated error time value.

    摘要: A fault clearing system and method for an engine control system includes a plurality of processor modules to control and monitor the engine and set a plurality of faults. The plurality of processor modules includes an electronic throttle control (ETC) module to control and monitor a throttle of the engine, and a plurality of engine sensors and ETC sensors. An ETC diagnostic module monitors the ETC sensors and engine sensors, with the ETC diagnostic module setting a low voltage induced fault. The ETC diagnostic module will also enter one of a plurality of low voltage states in response to the low voltage induced fault. The ETC diagnostic module selectively controls the ETC module and selectively clears the faults in the ETC module and plurality of processor modules upon entry into one of the low voltage states.
