Page 8: General Information
General information General information EMS 2 – Engine Management System (engine control system) EMS 2 is an electronic system with CAN communication (Controller Area Network) for controlling diesel engines. The system has been developed by Volvo and includes fuel regulation and diagnostic functions. The system comprises a control unit, six injectors, a number of sensors that supply the control unit with values and connectors for diagnostics and functional checks. - Page 9 General information DCU (Display Control Unit) The DCU is a digital instrument panel that communi- cates with the engine control unit via the CAN link. The DCU has several functions, such as: Engine control – Start, stop, engine speed regulation, pre-heating, etc.
