  • Method for static fault code synchronization in an internal combustion engine
    Patent number: 7984362
    Abstract: A method to synchronize Fault Code Memory between at least a first module and a second module in an engine controller unit; each said module in electronic communication with each other and having volatile and non volatile memory; said modules in electronic communication; when compatibility of versions of static fault codes between the modules is established, the first module downloads and saves the static fault code table resident on the second module in nonvolatile memory for access by a diagnostic tool.

  • Method of verifying component functionality on EGR and air systems
    Patent number: 7631552
    Abstract: In one aspect, the present invention is directed to a method for operating an electronically controlled internal combustion engine in a vehicle to perform at least one rationality check on at least one sensor to detect impending sensor failure and verify component functionality. The engine is equipped with an engine control system (ECS) having a memory and in electronic communication with various sensors. The sensors transmit data signals to the ECS indicative of associated engine and vehicle component functionality.
