What Is Car ECU?

by What is car ECU The vehicle computer is an electronic computer which used in modern auto motives to maneuver its computerized components. Gathering real time data from sensors and sending output to it's components, the vehicle ECU manage the proper maneuvering of the auto.

The engine control module obtain inputs from other modules in the car such as the fuel supply and crankshaft sensors to smartly process data like fuel consumption, cooling system, intake and some other components to estimate and maneuver the running working order of the transmission, engine system such as the lighting control, the traction control (ABS), the body functions etc.

A simple example is the wheel speed detector which calculate the car speed and transmits the data to the motor vehicle ECM. Using this infrastructure, instead of handing out information to several modules from one sensor, the information would be transferred by the auto's computer to all the components that use this data like the suspension system, speedometer, ABS etc.



On-board Diagnostics Port

OBD port An auto that was built with auto computer will also furnish On-board Diagnostics (OBD) port to enable officials or driver to plug diagnostic equipage if you wish to diagnose the auto ECM state.





Vehicle computer theft avoidance control

The engine immobilizer is anti theft mechanism placed on the auto motive ECM. It accomplishes prevention of the car from activating without employing a registered key. This system uses an exclusive transponder chipped key that saves the digital security PIN code or plainly the pass-code. The car computer system does not light up the fuel supply system and the ignition circuit if the code in the key does not match the code reserved in the immobilized computer.



Various vehicle producers use other types of car computers as the ECM (Engine Control Module), BCM (Brake Control Module), GEM (General Electric Module) and more. Latest automobile may contain many ECUs and with this growing complexity, the programming involved in resetting or configuring the vehicle ECM is becoming more troublesome to operate.
