Abstract
A method for detecting faults in an electrical system having a plurality of control lines and an error indicator line is disclosed. This method determines which of the plurality of control lines are active and whether the error flag line is indicating that a fault is present. One of the plurality of control lines is deactivated when the error flag line is indicating that a fault is present. Further, the method re-determines whether the error flag line is indicating a fault is present and then determines that a fault is present on the deactivated control line when the error flag line indicates that a fault is not present. In a further aspect of the present invention, the method re-activates the deactivated control line when the error flag line indicates that the fault is still present. These steps are repeated until the control line having a fault is identified.
