Electronic control unit (EBU)
The electronic control unit (EBU) is located behind the upholstery panel on the right side of car salon. EBU is a basic element of system of injection of fuel. EBU constantly receives signals from various sensors and exercises administration of the major systems and engine knots. Besides, EBU carries out functions of diagnostics of malfunctions of systems and engine knots. At detection of any malfunction of EBU includes a signaling device "Engine servicing" is required, defines and brings the corresponding code (codes) of malfunction in memory. It facilitates further carrying out problem diagnostics. On the car IEFI-6 type EBU is established. At refusal of EBU replaces ся assembled as does not contain maintainable elements. Parameters and algorithms of management are stored in the erased programmed constant I remember the shchy device (СППЗУ). The version of the program which has been written down in ROM, is designated by number EBU which corresponds to identification number of the car.
EBU carries out a food of various sensors and switches constant tension of 5 and 12 Century. Electric chains of EBU possess high resistance therefore at connection of plugs of a food with a control lamp the last does not burn.
It is necessary to apply the digital voltmeter to exact measurement of supply voltage with high full resistance (10 megohms). EBU operates work топливнык nozzles, the idling valve, compressor coupling etc. by means of special electronic devices (the 4th channel drivers), the target managing directors of signals of EBU intended for processing.
EBU is executed by the unattended. Therefore at EBU refusal it is subject to replacement assembled.
