What is Car ECU

02-04-2021 - The auto motive main computer is a computerized control unit which used in present day automotive's to manage its electric modules. Collecting data from sensors and sending output to it's components, the auto motive computer module alter the proper functioning of the auto motive.

The vehicle's computer gather information from other digital units in the automotive as the fuel supply and camshaft sensors to smartly compute information such as fuel consumption, exhaust, cooling system and a few other components to determind and manage the sustaining circumstance of the transmission, engine system like the body functions, the airbags, the camshafts position etc.

A typical example is the speed sensor located on the wheel which examine the car speed and transfer the information to the ECM. Using this infrastructure, rather than sending data to number of components from one detector, the data would be sent by the ECU to all the devices that need this information like the suspension system, ABS, speedometer etc.

On-board Diagnostics Port

A car that incorporate auto's computer will also provide On-board Diagnostics (OBD) provision to enable driver or officials to plug diagnostic computer and read the automotive computer module settings.

Auto motive main computer counter theft control

The car immobilizer is counter theft system placed on the ECU. It forestalls the engine from firing up without applying an accredited key. This mechanism adopts a unique transponder key that stores the electronic security pin or simply the passcode. The auto computer system wouldn't kindle the pressure of fuel system and the ignition lock if the pin-code in the key is different then the pin-code reserved in the immobilizer.

Various car makers use various types of ECUs including the PCM (Powertrain Control Module), GEM (General Electric Module, BCM (Brake Control Module)) and more. Latest vehicle accommodate several ECUs and with this growing complexity, the computing necessitate in configuring or resetting the automobile computer system is becoming way more troublesome to maintain.
