In Fig. 9.2 shows the appearance and the approximate location of the other connectors motor control Fenix 5.1. Electrical wiring connector is shown on the color tab. The control unit (CU) of 4/1 (Fig. 9.1) receives input signals from the sensors and engine components, describing the conditions of his work: - A signal of speed and position of the crankshaft, coming from the sensor 7/21 speed and position of the crankshaft; - A signal of a duty cycle of the cylinder sensor 7/27 camshaft. - A signal of a vacuum in the intake manifold pressure sensor 7/22; - A signal about the temperature of the intake air temperature sensor 7/24; - A signal of engine temperature sensor 7/23 engine coolant temperature; - A signal of throttle position sensor throttle position 7/25. - Signal mode, the combustion mixture with oxygen sensor 7/15 .; - A signal of the knock sensor Knock 7/26; - Signal mode is selected, air conditioning with climate control panel; - Signal on the functioning of the air conditioning compressor air pressure switch; - A signal of the pressure in the air conditioning system with high and low pressure; - Choice of transmission signal (for automatic transmission) with BU transmission; - A signal of the gear selector lever is in position P or N (for vehicles with automatic transmission) with BU transmission; - A signal of speed with a combination of devices. On the basis of these signals, ECU controls the following processes and mechanisms: - By controlling the fuel injection nozzle of each individual; - Ignition by supplying signals to the switch, which is integrally formed with the ignition coil. Frequency of rotation of idling with the help of a regulator of idling; - The fuel pump through the fuel pump relay. The main relay. Indicator lamp failure; - Electric cooling fan by fan relay. CU can (if necessary) to turn off the air conditioning compressor through the compressor relay. CU also transmits the following signals: - Confirmation signal torque control by reducing the ignition timing on the BU transmission; - Signals of speed and load on the BU transmission; - Signal the opening of the throttle valve in the automatic gearbox ECU. - A signal of the engine speed on the tachometer, located in the instrument cluster. - Engine temperature signal to the instrument cluster. The signal at the terminal block with diagnostic trouble codes output.
