Control units (ECU, TCU) coding, firmware

Modern vehicles are equipped with many electronic control modules that manage engine operation, transmission behavior, braking systems, safety features, and many other vehicle functions. Control units such as the ECU (Engine Control Unit) and TCU (Transmission Control Unit) often require coding, programming, or software updates after repairs, component replacement, or installation of new parts. At FIX SERVICE in New York we perform professional diagnostics of electronic systems using original dealer-level diagnostic equipment. We replace control modules when they are damaged, for example after water intrusion, electrical failure, or accident damage, and we properly code and program the new modules so the vehicle systems operate correctly. Our shop regularly works with popular brands such as Audi, Volkswagen, Mercedes-Benz, BMW, Ford, Toyota, and Lexus. In many cases we perform the same programming and coding procedures that are typically done at official dealerships, using professional tools and factory-level software.
