Algorithm for detecting faults on electrical control lines

A method for detecting faults in an electrical system having a plurality of control lines and an error indicator line, wherein the error indicator line indicates that there is a fault present on at least one of the plurality of control lines, the method comprising:

• (a) determining which of the plurality of control lines are active;
• (b) determining whether the error flag line is indicating that a fault is present;
• (c) deactivating one of the plurality of control lines when the error flag line is indicating that a fault is present;
• (d) re-determining whether the error flag line is indicating a fault is present;
• (e) determining that a fault is present on the deactivated control line when the error flag line indicates that a fault is not present;
• (f) re-activating the deactivated control line when the error flag line indicates that the fault is still present;
• and
• (g) repeating steps (a) through (f) until the control line having a fault is identified.

A method for detecting faults in an electrical system having a plurality of control lines and an error indicator line, wherein the error indicator line indicates that there is a fault present on at least one of the plurality of control lines, the method comprising:

• (a) determining which of the plurality of control lines are active;
• (b) monitoring the error flag line at predefined time intervals;
• (b) determining whether the error flag line is indicating that a fault is present;
• (c) deactivating one of the plurality of control lines when the error flag line is indicating that a fault is present;
• (h) re-determining whether the error flag line is indicating a fault is present;
• (i) determining that a fault is present on the deactivated control line when the error flag line indicates that a fault is not present;
• (j) re-activating the deactivated control line when the error flag line indicates that the fault is still present;
• and
• (k) repeating steps (a) through (f) until the control line having a fault is identified.
