What Is Car ECU?
by Terry Young -
The engine control unit is an electronic computer which used in present day autos to manage its electronic components. Gathering real time data from sensors and sending output to the different module, the engine control unit alter the appropriate functioning of the auto motive.
The automotive's computer gather information from the different digital units in the vehicle such as the crankshaft and camshaft sensors to effectively compute data as combustible fuel system, intake, cooling system and some other components to evaluate and manage the running circumstance of the engine, transmission system like the traction control (ABS), the lighting control, the camshafts position etc.
A typical illustration is the wheel speed sensor which examine the speed of the wheel and send the data to the auto ECM. This way, instead of sending signals to several modules from one detector, the signals is being transferred by the automobile computer to all the devices that makes use of this data like the suspension system, speedometer, ABS etc.
On-board Diagnostics Port
A motor vehicle that was built with auto motive computer will also arrange On-board Diagnostics (OBD) port to enable driver or officials to plug diagnostic equipage if you wish to check the automotive ECM settings.
Engine control unit theft elimination control
The car immobilization system is theft elimination mechanism placed on the motor vehicle computer system. It accomplishes prevention of the ignition from activating unless applying a commissioned key. This platform adopts a special chipped key that saves the electrical security pin or in other words the password. The vehicle's computer wouldn't power on the fuel system instrumentation and the ignition lock if the PIN code in the key isn't in sync with the PIN code stored in the immobilization system.
Worldwide car-makers use several types of ECUs including the BCM (Brake Control Module), GEM (General Electric Module, ECM (Engine Control Module)) and others. Latest vehicle accommodate a few dosen ECUs and due to their increasing complexity, the computing necessitate in resetting or configuring the automobile computer module is becoming more difficult to control.
