    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: An engine system includes a status determination module and an open-loop fuel control module. The status determination module determines whether a first ignition fuse is in a failure state. The open-loop fuel control module disables a first plurality of fuel injectors and actuates a second plurality of fuel injectors based on a first air/fuel (A/F) ratio when the first ignition fuse is in the failure state, wherein the first ignition fuse and the first plurality of fuel injectors correspond to a first cylinder bank, and wherein a second ignition fuse and the second plurality of fuel injectors correspond to a second cylinder bank.

    摘要: A control system and method for controlling pump includes a pump control module communicating a drive signal to the high pressure pump and a high pressure pump in communication with the pump control module operating in response to the drive signal. A current sampling module samples a pump current signal to form a sample prior to an end of the drive signal. A current comparison module compares the sample to a threshold that may be a function of pump solenoid resistance, pump solenoid temperature, and/or system voltage, and a fault indication module generates a fault signal in response to comparing.

    摘要: A diagnostic system comprises a monitoring module and a diagnostic module. The monitoring module receives a first rail pressure measured by a high side rail pressure sensor during engine cranking at a location where fuel is pressurized by a high pressure fuel pump. The diagnostic module selectively diagnoses a fault in at least one of the high pressure fuel pump and the high side rail pressure sensor when the first rail pressure is less than a predetermined pressure and rail pressures received during a predetermined period after the first rail pressure is received are less than the predetermined pressure.
