What Is Car ECU?
by Terry Young -
The auto motive ECM is an electric computer which used in present day cars to maneuver its computerized components. Reading real time data from sensors and sending output to it's components, the engine control unit control the appropriate operation of the automobile.
The auto motive ECU obtain data from the different modules in the car such as the camshaft and fuel consumption sensors to effectively process data such as exhaust, injection fuel supply, intake and some other components to estimate and maneuver the running state of the transmission, engine system like the camshafts position, the AC, the airbags and more.
A common illustration is the wheel speed detector which examine the car speed and transfer the data to the motor vehicle's computer. This way, instead of sending information to number of modules from one detector, the information is being distributed by the engine control unit to all the wired units that makes use of this data such as the suspension system, ABS, speedometer and more.
On-board Diagnostics Port
A motor vehicle that was built with car ECM will also feather On Board Diagnostics (OBD) interface to let driver or officials to connect diagnostics equipment in order to evaluate the ECM state.
Auto motive ECM anti theft control
The car immobiliser is anti theft mechanism partition in the automobile computer. It forbids the car from turning on unless driver is employing a commissioned key. This system employs a unique transponder key that saves the digital security PIN code or plainly a pass-code. The car computer wouldn't kindle the fuel consumption system and the ignition lock if the code in the key is different then the code stored in the immobilized computer.
Various car-makers use other types of car computers including the BCM (Brake Control Module), GEM (General Electric Module, PCM (Powertrain Control Module)) and more. Contemporary vehicle might have many ECUs and because of this increasing complexity, the coding involved in resetting or configuring the ECU is becoming more difficult to control.
