Check
On all ESM models fastens on the right under the dashboard.
At the working engine with finger-tips sharply knock on a module wall, - if ESM is faulty, the postukivaniye can lead to violation of stability of turns of the engine, at the same time on the display connected to system of onboard diagnostics (OBD) of the scanner the current data on characteristics of operation of the engine will be highlighted.
Before starting replacement of the module check serviceability of a condition and reliability of fastening of contact connections of electroconducting of its chain. Each contact socket is painted in individual color that excludes probability of the wrong connection of electroconducting at ESM installation. In the absence of obvious signs of violation of serviceability of functioning of the module of management the car should be driven away on car repair shop for carrying out more detailed diagnostics of the module.
