ABSTRACT:
A method of detecting electrical faults that may occur in a vehicular air suspension system utilizing height sensors and air springs mounted between sprung and unsprung components of the vehicle. The method involves defining specific signals that are available from a properly functioning and an improperly functioning height sensor during both its energized and de-energized conditions and comparing the output signals with the defined signals to determine fault occurrences and communicating that event to the vehicle operator when the number of detected fault occurrences exceed a predetermined number.
