What Is Car ECU?

by What is car ECU The engine control unit is an electric computer which used in modern autos to control its computerized components. Interpreting data from sensors and sending output to it's components, the auto motive's computer manage the proper functioning of the automobile.

The ECM obtain information from various modules in the auto like the camshaft and crankshaft sensors to cleverly process data like exhaust, cooling system, injection fuel system and some other internal components to determind and control the running state of the transmission, engine system as the camshafts position, the body functions, the lighting control and so on.

A typical example is the wheel speed detector which calculate the wheel speed and transfer the data to the automotive's computer. Using this infrastructure, instead of handing out data to multiple wires from one sensor, the data is being sent by the car's computer to all the wired units that use this data as the speedometer, suspension system, ABS and so on.



On-board Diagnostics Port

Engine control unit theft elimination control

The car immobilization computer is counter theft infrastructure partition in the motor vehicle main computer. It forbids the ignition from flaring up without employing a certified key. This platform employs a special chipped key that saves the digital security pin-code or simply a password. The ECM does not power on the injection fuel supply system and the ignition lock if the code in the key does not match the code stored in the immobilizer.



Worldwide auto manufacturers use several types of car computers including the PCM (Powertrain Control Module), BCM (Brake Control Module), GEM (General Electric Module) and others. Newer vehicle accommodate a few dosen ECUs and because of this increasing complexity, the programming entailed in configuring or resetting the engine control unit is becoming more and more challenging to operate.
