ЕСМ - the general information, an estimation of a condition and replacementThe general information
Function chart of an electronic control system of the engine
The scheme of an arrangement of components of control system АТ
ECM is the electronic module on the basis of the microprocessor which on the basis of the analysis of signals arriving from various information gauges exercises administration of functioning of systems of injection, ignitions and decrease in toxicity of the fulfilled gases.
Into number carried out ECM problems enter:
In memory of the module emergency values (values by default) the basic working parametres of all subsystems of management are put. The given parametres are activated in case of revealing of refusal of a corresponding subsystem, providing adequacy of functioning of the engine (with inevitable loss of efficiency of return).
Refusal of any subject to monitoring from outside the block of self-diagnostics of a component is fixed in memory of the module in the form of the corresponding five-place code, which reading can be made by means of the special scanner (the Section System of onboard diagnostics (OBD) - a principle of functioning and codes of malfunctions see. Signals in management chains).
On all models ЕСМ fastens on the right under the panel of devices.
At the working engine with finger-tips sharply knock on a processor wall, - if ЕСМ it is faulty, постукивание can lead to infringement of stability of turns of the engine, simultaneously on the display of the scanner connected to system OBD current data on characteristics of work of the engine will be highlighted.
Before to start module replacement check up serviceability of a condition and reliability of fastening of contact connections of electroconducting of its chain. Each contact socket is painted in individual colour that excludes probability of wrong connection of electroconducting at installation ЕСМ. In the absence of obvious signs of infringement of serviceability of functioning ЕСМ the car should be driven away on a car repair shop for carrying out of more detailed diagnostics of the module.
Installation is made upside-down
