What Is Car ECU?

by What is car ECU The auto main computer is an electronic computer which used in modernised autos to control its electronic components. Reading real time data from sensors and sending output to the different components, the motor vehicle's computer manage the proper functioning of the automotive.

The automobile computer module obtain inputs from other modules in the vehicle such as the consumption of fuel and crankshaft sensors to cleverly process data as intake, exhaust, cooling system and some other components to evaluate and control the driving condition of the transmission, engine system such as the ignition/injection timing, the airbags, the lighting control and others.

A typical example is the wheel speed sensor which examine the speed of the wheel and transmits the data to the automobile ECU. Using this infrastructure, instead of distributing messages to several modules from one sensor, the messages would be transferred by the automobile ECM to all the wired units that are interested in this data such as the suspension system, speedometer, ABS and others.



On-board Diagnostics Port

OBD port A car that incorporate motor vehicle computer will also feather On-board Diagnostics (OBD) outline to enable officials or driver to plug diagnostics equipment to inspect the auto computer state.





Auto main computer counter theft control

The car immobilizer is anti theft system placed on the auto motive ECM. It bars the car engine from starting unless driver is employing a registered key. This mechanism adopts an exclusive chipped key that holds the electronic security pin or plainly a password. The ECU does not light up the pressure of fuel instrumentation and the ignition lock if the code in the key is different then the code reserved in the immobilized computer.



Various automakers use different types of car computers such as the ECM (Engine Control Module), BCM (Brake Control Module), GEM (General Electric Module) and more. Contemporary auto may contain many ECUs and because of this increasing complexity, the computing required in configuring or resetting the motor vehicle's computer is turning much more troublesome to handle.
