    摘要: 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.
