Functional description

The engine control unit M10 monitors and controls the entire electronic ignition and injection system. The system is supplied directly by the battery via a line protected by the maxifuse EFI located on the battery, connector B99 C . The supply controlled by the ignition (15/54) arrives from the line protected by fuse F4 of the additional fuse box B98 A . The control unit M10 is supplied directly by the battery at pin 15 of connector A, via a line protected by fuse F5 of the additional fuse box B98 A . The supply controlled by the ignition reaches pin 47 of connector A, via a line protected by fuse F4 of the additional fuse box B98 A . Main injection relay J10 controls the entire system: this is excited by a control signal (earth) from pin 31 of connector A of control unit M10 and then sends a power supply to pins 16, 32 and 48 of connector A of the control unit via a line protected by fuse F3 of supplementary fuse box B98 A. to air flow meter K41, fuel vapour recovery solenoid L10, variable geometry contol solenoid L15, variable valve timing actuator N76 and lambda sensors K15, K16 and K17; (all these lines are protected by fuse F2 of B98 A ). to the injectors N70 and the coils A30 , via the line protected by fuse F3 , located in the unit B98 A . the fuel pump relay J15 receives a supply controlled by the ignition via fuse F4 , of the additional fuse box B98 A . It is energized by a control signal (earth) from pin 30 of connector A of control unit M10 and supplies power to fuel pump N40 , which is earthed through the inertia switch I50 , which cuts off the circuit in the case of a crash and so prevents the dangerous spilling of fuel. On the control unit, the earth point C40 C is located, which connects to the engine earth C40 A . The engine control unit M10 receives signals from the various sensors in order to monitor all engine service conditions. Rpm sensor K46 provides information on engine speed via a frequency signal sent to pins 10 and 59 of connector B of control unit
