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 motor vehicle engine includes an operator controlled fuel injection enabling switch effective to disconnect electric fuel injection apparatus from an electric power source and thus initiate the cessation of engine operation when deactivated. However, the spark ignition system is still powered through an oil pressure switch so as to continue engine operation for a few extra crankshaft rotations to reduce the unburned fuel in the intake passage as the engine stops and thus reduce throttle bore coking. In a vehicle having a fuel pump relay activated by the fuel injection enabling switch with contacts connected across the oil pressure switch, the invention may be obtained by changing the power connection of the spark ignition system from the fuel injection enabling (ignition) switch to the fuel pump relay.

摘要： A method for isolating voltage sensor errors from contactor errors in an electrical system includes measuring a voltage between ground and a voltage bus rail when a contactor is open, and comparing the measured voltage to a first threshold voltage corresponding to a calibrated voltage reading that is expected when the contactor is closed. A first diagnostic code is recorded with a stuck-in-range status for the sensor when the measured voltage is greater than 0 and less than the first threshold voltage. A second diagnostic code is recorded with a stuck-closed status for the contactor when the measured voltage is equal to the first threshold voltage. The measured voltage may be compared to a second threshold voltage that exceeds the first threshold voltage, with a third diagnostic code recorded with a shorted value for the sensor when the measured voltage exceeds the first threshold voltage or is less than 0.

The DC converter is coupled to the RESS. The controller is coupled to the DC converter, and is configured to determine a status of the engine, receive a DC converter voltage value from the DC converter, and provide diagnostics for the DC converter based on the engine status, RESS voltage, and the DC converter voltage.
