Dongfeng Tianlong's DCU is located next to the urea tank. Meaning of DCU: DCU stands for Diesel Control Unit, which is the core of electronically controlled fuel injection, commonly known as the engine computer. It is a type of traction control unit. DCU control principle: The Dosing-Control-Unit (DCU) monitors vehicle status in real-time through sensors and precisely controls actuators via software calculations to achieve accurate system control. It can be integrated into Bosch EDC17CV electronic control units.
I'm a truck driver who operates Dongfeng Tianlong, quite familiar with vehicles. The DCU is located in the engine compartment, usually on the left side near the firewall, mounted on a bracket. You can see it when you open the hood—it's a black or gray box. The placement is well chosen, with good dust and water resistance, making maintenance quick and easy. I always take a quick look before driving to ensure the wiring harness isn't loose and there isn't too much dust, which keeps the vehicle running stably with fewer faults. If the DCU has an issue, the dashboard will alert you. Its easily accessible location saves a lot of repair time, and I recommend regular cleaning around it to prevent overheating. The sensible placement also minimizes interference with other components, ensuring smooth power output.
