What Is Car ECU?

by What is car ECU The vehicle main computer is an electronic control unit which used in present day autos to manage its electronic components. Gathering input from sensors and sending output to it's components, the automobile's computer control the appropriate operation of the vehicle.

The ECU gather information from the different modules in the automotive such as the crankshaft and camshaft sensors to cleverly process information such as intake, cooling system, exhaust and several other components to evaluate and manage the operating working order of the transmission, engine system like the AC, the body functions, the ignition/injection timing etc.

A simple example is the speed sensor located on the wheel which examine the car speed and transmits the information to the automotive computer system. Using this infrastructure, instead of handing out information to several components from one sensor, the information is being distributed by the automobile main computer to all the components that need this information like the suspension system, speedometer, ABS etc.



On-board Diagnostics Port

OBD port An automotive that was built with vehicle computer system will also feather OnBoard Diagnostics (OBD) provision to enable officials or driver to plug diagnostic computer in order to read the auto ECM state.





Vehicle main computer anti theft control

The car immobilization computer is theft deter system placed on the auto's computer. It accomplishes prevention of the engine from starting up unless utilizing an accredited key. This mechanism uses a unique transponder chip key that holds the electronic security PIN code or in other words the pass-code. The auto's computer doesn't power on the fuel pump instrumentation and the ignition circuit if the pin-code in the key is not in sync with the pin-code reserved in the immobiliser.



Various automakers use several types of ECUs as the ECM (Engine Control Module), BCM (Brake Control Module), PCM (Powertrain Control Module)) and more. Contemporary auto may contain several ECUs and because of this development, the coding necessitate in resetting or configuring the auto motive's computer is becoming more and more troublesome to maintain.
