This 202V25803-7923 electronic control unit (ECU) is an original engine control module tailored for the MT13 China VI diesel engine, widely installed on Foton Auman GTL, EST and ETX heavy-duty trucks. As the core brain of the engine powertrain system, it precisely controls fuel injection volume, injection timing, air intake regulation, exhaust aftertreatment operation, torque output limitation and real-time fault diagnosis to fully comply with China VI emission standards. Equipped with industrial-grade core chips and optimized circuit layout, this ECU features excellent high-temperature resistance, vibration resistance and electromagnetic anti-interference capability, adapting to heavy-load, long-distance and complex road working conditions. All interface circuits and pin definitions strictly follow original OEM standards to ensure stable and accurate signal transmission. Every unit undergoes full functional testing, program verification and long-time aging inspection before delivery, serving as a standard replacement part for faulty MT13 China VI engine control modules.
