The electronic block of management (ECU)
The electronic block of management (ECU) is located behind the panel of an upholstery on the right side of car salon. ECU is a basic element of system of injection of fuel. ECU constantly receives signals from various gauges and exercises administration of the major systems and engine knots. Besides, ECU carries out functions of diagnostics of malfunctions of systems and engine knots. At detection of any malfunction ECU includes a signalling device "engine servicing" Is required, defines and brings a corresponding code (codes) of malfunction in memory. It facilitates further problem diagnostics carrying out. On the car it is established ECU type IEFI-6. At refusal ECU replaces ся in gathering as does not contain maintainable elements. Parametres and algorithms of management are stored in the erased programmed constant I remember щем the device (СППЗУ). The variant of the program which have been written down in ROM, is designated by number ECU which corresponds to identification number of the car.
ECU carries out a food of various gauges and switches constant pressure 5 and 12 V.Elektricheskie chains ECU possess high resistance, therefore at connection of plugs of a food with a control lamp last does not burn.
It is necessary to apply the digital voltmeter to exact measurement of pressure of a food with high full resistance (10 МОм). ECU operates work топливнык atomizers, the idling valve, compressor coupling etc. By means of special electronic devices (4 channel drivers), target operating signals ECU intended for processing.
ECU it is executed by the unattended. Therefore at refusal ECU it is subject to replacement in gathering.
At replacement ECU, ycтановленного at factory, it is necessary to transfer on the tablet new ECU a code and a works number old ECU. It is not necessary to make entry on case EBU. This information can be demanded in the further operation of the car.
In order to avoid failure ECU any operations connected with switching of wires of food ECU, for example, joining or switching-off of sockets ECU, a safety lock, wires of the storage battery, lengthening wires etc.), it is necessary to carry out only at the switched off ignition.
