This OBD-II data link module, also known as a smart data link module or gateway module, matches the fit, function and performance of a factory module on specified Ford and Lincoln vehicles. Situated under the dashboard below the steering column, this module ensures communications between the controller area network (CAN) bus and devices and tools that utilize the onboard diagnostic port. When the original equipment data link module fails from electrical malfunction or data corruption, various modules that control critical vehicle engine and electronic functions can stop responding. The results of that communication breakdown can range from vehicle convenience features becoming disabled, to the activation of engine limp mode. This direct-replacement module is engineered to restore all communications among vehicle systems to factory specifications.
