Abstract
A fault code analyzer for a vehicle includes a fault code memory device configured to store a plurality of active and inactive fault codes for the vehicle and a priority processor coupled to the memory device. The priority processor is configured to: prioritize each fault code within the plurality of active and inactive fault codes; determine a first root cause fault code, the first root cause fault code corresponding to the highest prioritized fault code; determine a first set of interaction fault codes, the first set of interaction fault codes relating to the first root cause fault code; and provide the first root cause fault code and the first set of interaction fault codes to an interface device of a user.
