DDEC VI System

The engine is equipped with a fully electronic control system, which regulates the fuel injection quantity and timing using solenoid valves, allowing extremely low-emission operation. Besides the engine and its related sensors, the system is composed of the following:

• The Motor Control Module (MCM)
• The Common Powertrain Controller (CPC) located under the right-hand dash panel.

The two control units are connected by a proprietary datalink through which all necessary data and information can be exchanged.

The CPC then broadcasts all information on the J1587 and J1939 datalinks, where it can be read by the diagnostic tool.

The engine control system monitors both the engine and the datalink. When a malfunction or other problem is detected, the system selects an appropriate response; for example, the emergency running mode may be activated.

The Accelerator Pedal Assembly (AP) eliminates the need for any throttle linkage.
