What Is Car ECU?
by Ivan Rushel -
The engine control unit is an electrical computer which used in modernised automobiles to manage its electronic components. Collecting data from sensors and transmitting output to digital units, the motor vehicle ECM control the proper maneuvering of the auto.
The vehicle computer module obtain information from various components in the auto such as the crankshaft and camshaft sensors to effectively compute data as injector of fuel , exhaust, cooling system and several other internal components to evaluate and manage the sustaining circumstance of the transmission, engine system like the body functions, the fluid flow, the camshafts position and more.
A typical example is the wheel speed detector which examine the wheel speed and transfer the data to the automobile computer module. This way, instead of handing out messages to multiple components from one sensor, the messages is being sent by the auto motive's computer to all the wired units that use this data like the speedometer, ABS, suspension system and more.
On-board Diagnostics Port
A motor vehicle that accommodate vehicle computer will also outfit OnBoard Diagnostics (OBD) port to enable officials or driver to plug diagnostics equipage if you need to diagnose and configure the vehicle's computer state.
Engine control unit counter theft control
The car immobilization system is anti theft system partition in the ECM. It forestalls the ignition from starting unless employing a commissioned key. This system uses a special transponder key that holds the digital security pin-code or in other words a passcode. The vehicle computer module doesn't power on the injection fuel supply infrastructure and the ignition lock if the pin-code in the key is not in sync with the pin-code reserved in the immobiliser.
Different vehicle producers use other types of car computers as the ECM (Engine Control Module), BCM (Brake Control Module), GEM (General Electric Module) and others. Latest vehicle might have many ECUs and with this increasing complexity, the coding involved in resetting or configuring the engine control unit is becoming much more troublesome to operate.
