What Is Car ECU?

by What is car ECU The engine control unit is a computerized computer which used in modern vehicles to control its electronic components. Interpreting data from sensors and sending output to the different components, the auto's computer manage the proper operation of the motor vehicle.

The engine control unit obtain data from various digital units in the vehicle as the crankshaft and injection fuel system sensors to cleverly process information like intake, cooling system, exhaust and several other components to evaluate and control the driving circumstance of the transmission, engine system as the body functions, the AC, the airbags and more.

A typical example is the speed detector found on the wheel which detects the car speed and transmits the information to the car ECM. This way, rather than distributing signals to multiple wires from one detector, the signals would be delivered by the vehicle computer module to all the wired units that makes use of this information as the ABS, speedometer, suspension system and more.

On-board Diagnostics Port

OBD port An auto that incorporate car ECU will also feather OnBoard Diagnostics (OBD) port to let driver or officials to connect diagnostics computer to evaluate the ECU settings.

Engine control unit anti theft control

The car immobilizer is theft elimination infrastructure partition in the automobile ECM. It prevents the ignition from igniting without using an accredited key. This mechanism adopts a special chipped key that saves the electronic security pin or in other words the passcode. The auto motive computer system wouldn't light up the fuel injector instrumentation and the ignition lock if the PIN code in the key is different then the PIN code reserved in the immobilization computer.

Worldwide car-makers use other types of ECUs like the GEM (General Electric Module, ECM (Engine Control Module), BCM (Brake Control Module)) and others. Latest car accommodate a number of ECUs and because of this growing complexity, the coding required in configuring or resetting the automobile main computer is becoming more difficult to control.
