169002436 - E5030 PETROL ENGINE ELECTRONIC MANAGEMENT - OPERATIONAL DESCRIPTION (POWERED THROTTLE)
Operational description
The engine management control unit M010 is connected directly to the battery earth A001 connector D from connector A pin 5, 6, 21, 22.The direct battery power supply is provided at pin 16 connector B, from the line protected by fuse F 18, housed in the engine compartment junction unit B001.The ignition-operated supply is supplied:
- to the engine management control unit M010, at pins 29 and 12 of connector B;
- to the coil, incoming, for the relay housed inside the engine compartment junction unit B001;
When energized, the relay provides a direct battery power supply:
- to the Lambda sensors K017 and K018 (at pins 4 respectively);
- to the fuel vapour recovery solenoid valve L010 (pin 2).
- to the ignition coils A030, connector A and B (at pins 1 respectively);
- to the injectors N070, connector A, B, C, D (at pins1 respectively);
- to the fuel pump N040;
From connector A, the control unit M010:
- is connected to coolant temperature sensor K036 at pins 36 and 45;
- from pins 13 and 7 provides the power supply and the reference earth respectively to the integrated air temperature sensor K043 and the timing sensor K047;
- at pins 31 and 63 it receives the absolute air temperature and pressure signals respectively supplied by sensor K043;
- at pin 24 it receives the engine timing sensor signal K047;
- at pin 51 it controls the fuel vapour recovery solenoid valve L010;
- at pins 17 and 19 it controls the coils A030;
- at pins 50, 34, 49, 33 it controls the injectors N070;
- from pins 23 and 9 it provides the power supply and reference earth respectively for the engine rpm sensor K046;
- from pins 41 and 48 it provides the power supply and reference earth respectively for the detonation sensor K046;
- from pins 57, 52 it provides the power supply and reference earth for the throttle casing solenoid valve electric motor L062;
- at pin 30, 44 it receives signals coming from the throttle casing solenoid valve L062;
- from pins 15, 44 it provides the power supply and earth for the internal device for the throttle casing solenoid valve L062 for calculating the angular position of the actual throttle casing.
- at pins 32, 60, 43 it is connected to the Lambda sensor K017;
- at pins 64, 58, 42 it is connected to the Lambda sensor K018.
From connector B, the control unit M010:
- from pins 2, 3 provides the power supply for the accelerator pedal potentiometer K055;
- from pins 15, 46 provides a negative signal for the accelerator pedal potentiometer K055;
- at pins 40, 42 receives the signals from the accelerator pedal potentiometer K055;
- at pin 7 it receives the engine oil pressure sensor signal K028;
- at pin 50 it receives the signal from the clutch pedal switch I031;
- at pin 58 it controls the switching on of the "engine system failure" warning light housed in the instrument panel E050 (for more details See E4010 INSTRUMENT PANEL);
- at pin 10 it is connected to the diagnostic socket See E8010 DIAGNOSTIC MULTIPLE CONNECTOR.
