The DDEC-ECU is one of two electronic controllers that make up the IES that is used in
commercial vehicles with the MBE 900 engine. The separation of functions of each controller is
such that the DDEC-VCU senses and controls the vehicle-influencing parameters such as cruise
control, while the DDEC-ECU covers engine operating parameters as described above.
