DescriptionAn 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 system is managed by a single control unit that controls the twin spark ignition (static and lost spark), and the injection (phased).The system uses signals received from numerous sensors to control actuators. It is connected to the following systems:fuel supply;air supply system;engine cooling;exhaust with catalytic converter;fuel vapour recirculation; For further details, see DESCRIPTION AND OPERATION 1056Supply lines to the control unit and the various system components (sensors and actuators) are protected by a special maxifuse and another protects the steering wheel fuses, located with the relays in a service tank (behind the engine bulkhead).
Functional description Engine control unit M10 manages the electronic ignition and injection system. System power is distributed by main injection relay J10. When ignition key sends an INT/A supply via fuse F16 of control unit B1, power is sent to pin 47 connector A of control unit M10 and the coils of relays J10 and J15. The control unit then energises the coil of relay J10 via pin 31 of connector A and fuel pump relayJ15 from pin 30 of connector A. The connector contact takes power from the battery vai MAXIFUSE B80 that supplies fuel pump N40 via F3 of B1. The pump earth is supplied by inertia switch I50, which cuts off the fuel flow in the case of impact. The contact of main relay J10, supplied from the battery via MAXIFUSE B80, distributes power to the following devices:via fuse B41 to:1) control unit M10 at pins 16-32-48,2) injectors N70,3) ignition coils A30;via fuse B40 to:4) fuel vapour recovery solenoid L10,5) variable geometry control solenoid L15,6) variable valve timing actuator N76,7) pre and post converter lambda sensors K15-K16-K17,8) air flow meter K41.Control unit M10 controls the various engine service parameters by means of input signals from the following sensors:rpm sensor K46 on pins 10 and 59 of connector B; this supplies a frequency signal proportional to engine rpm.timing sensor K47; this is supplied from pin 26 of connector B (positive) and receives an earth signal from pin 42. pin 51 receives a frequency signal proportional to engine phaseengine temperature sensor K36 at pin 25 connector B; this supplies a signal proportional to engine coolant temperature. It is supplied via pin 26 of connector B. It also contains the transmitter for the instrument panel (see E4010 - STRUMENTO ON-BOARD INSTRUMENT).lambda sensor on preconverter K15 at pins 2-7-39 connector B;lambda sensor on preconverter -2 K16 at pins 23-34-55 connector B;lambda sensor on post converter K17 at pins 28-50-36 connector B.This supplies control unit M10 with information on the correct air-fuel mixture composition:knock sensor K50 at pins 22 and 54 connector B; this sends the control unit a signal representing engine knock conditionsair flow sensor K41 at pins 25-54-57-63; This sends a signal proportional to the air flow rate. Accelerator pedal K55 is fitted with two built-in potentiometers (a main one and a safety back-up). These are connected to control unit M10 via pins 7-8-24-25-40-56 connector A.The purpose of the above potentiometers is to notify the control unit of accelerator pedal position and thus the engine power requirement. On the basis of signals received from the accelerator pedal and the various sensors, control unit M10 drives injectors N70 via pins 3-19-35-52, ignition coils A30 via pins 14-16-30-31 and the built-in throttle body actuator N75 at pins 1-17-24-26-33-40-49-58.The throttle body is fitted with two potentiometers connected in parallel; this controls throttle opening via a step motorOn the basis of input parameters, control unit M10 controls variable valve timing actuator N76 (pin 36 connector B), fuel vapour recovery valve10 (pin 5 connector B) and the variable geometry control solenoid L15 of the turbine (pin 4 connector B). Table E5030 shows other electrical/electronic systems on the vehicle that interact with control unit M10:pins 9-41-50-62 connector A control ENGINE COOLING E5020;pin 3 connector A receives a signal from the ALFA ROMEO CODE control unit E7010;pins 6-13 connector A refer to ACTIVATION OF COMPRESSOR E6021 to adjust engine speed to the load increase whenever this is activated or compressor deactivation when engine speed and load is high.pins 12 and 29 connector A refer to the ASR/TCS E7021 system (antislip function).pins 19-22-35 connector A interact with ON-BOARD INSTRUMENT panel E4010.pin 27 connector A receives a signal from the brake pedal (see E7020 - ABS without VDC). Control unit M10 is fitted with a self-diagnostic system; it is connected to pin 7 of connector R10 via pin 53 connector A. this system can be used to analyse the injection system using external diagnostic instruments. Control unit M10 also sends an earth signal via pin 46 of connector A to turn on the injection fault warning light on instrument panel E50.
