The automobile ECM is an electrical control unit which used in present day cars to control its computerized modules. Collecting real time data from sensors and sending output to the different module, the automotive computer module manage the appropriate functioning of the vehicle.

The auto motive's computer gather inputs from the different modules in the auto such as the camshaft and combustible system sensors to effectively compute information like cooling system, exhaust, intake and a few other components to assest and control the driving situation of the transmission, engine system like the traction control (ABS), the airbags, the camshafts position and so on.

A simple illustration is the speed detector found on the wheel which examine the wheel speed and transmits the information to the car computer. This way, instead of distributing signals to number of wires from one detector, the signals would be transferred by the engine control module to all the wired units that need this information such as the suspension system, speedometer, ABS and so on.

On-board Diagnostics Port

A car that incorporate automobile computer will also arrange On Board Diagnostics (OBD) interface to enable driver or officials to plug diagnostics equipage to diagnose and configure the engine control module condition.

Automobile ECM theft elimination control

The car immobilization computer is antitheft system built in the ECM. It forestalls the ignition from turning on unless employing a commissioned key. This infrastructure employs a special transponder chip key that stores the electrical security code or simply the passcode. The automotive main computer wouldn't start up the combustible fuel supply infrastructure and the ignition switch if the code in the key is different then the code stored in the immobilizer.

Worldwide automakers use other types of ECUs such as the ECM (Engine Control Module), GEM (General Electric Module, BCM (Brake Control Module)) and more. Latest auto might have a number of ECUs and due to their growing complexity, the coding required in configuring or resetting the engine control module is becoming way more troublesome to maintain.
