Description - DIESEL ENGINES ELECTRONIC MANAGEMENT - Fiat DOBLO 1.9 DIESEL da 12/03
An electronic management system supervises and governs all engine parameters. It optimises performance and fuel consumption by responding in real time to different service conditions.The Diesel engine is fitted with a LUCAS EPIC rotary distributor type injection system. This features the pumping/distribution principle which ensures the supply to the injectors, the fuel metering and the injection advance.
Functional description - DIESEL ENGINES ELECTRONIC MANAGEMENT - Fiat DOBLO 1.9 DIESEL da 12/03
The engine control unit M10 monitors and controls the LUCAS EPIC electronic injection system. The control unit receives a supply controlled by the ignition (15/54) at pin 81 from the line protected by fuse F21 and controlled by relay R10 . The signal which controls the coil for the relay R10 coming out of pin 11 connector F of the engine compartment junction unit B01 is earthed through a bridge between pins 3 and 4 of the electric fuel pump N40 and the inertia switch I50 . In the case of an impact it interrupts the supply for the control unit M10 .The relay R9 controls the system supply: it receives a supply from the battery at pin 1 of connector A of the engine compartment junction unit B01 ; the coil is supplied by the same line and is energized by an earth signal coming from the control unit M10 , from pin 82. This energizing makes it possible to supply pins 76 and 77 of the control unit M10 via fuse F17 of the engine compartment junction unit B01 .
