  • Patent number: 8050813
    Abstract: A control system comprising a powertrain relay diagnostic module that determines a single continuous period that a powertrain relay voltage is less than an ignition relay voltage, that compares the single continuous period to a single predetermined period, and that diagnoses a powertrain relay out of correlation (OOC) error when the single continuous period is greater than or equal to the single predetermined period, and an ignition relay diagnostic module that diagnoses an ignition relay OOC error when the ignition relay voltage is less than the powertrain relay voltage for a first predetermined cumulative period within a first predetermined total period.
    Type: Grant
    Filed: February 10, 2009
    Date of Patent: November 1, 2011
    Inventors: Joseph M. Stempnik, Paul A. Bauerle, Debbie L. Makowske, Tracey A. Bagley-Reed, Sandra J. Nelson
  • Patent number: 7792633
    Abstract: A control system comprising an ignition fuse diagnostic module that determines a state of an ignition fuse associated with an ignition coil of an engine cylinder, and a fuel control module that selectively operates a fuel injector associated with the engine cylinder based on the state of the ignition fuse. A method comprising determining a state of an ignition fuse associated with an ignition coil of an engine cylinder, and selectively operating a fuel injector associated with the engine cylinder based on the state of the ignition fuse.
    Type: Grant
