What Is Car ECU?

by What is car ECU The vehicle computer module is an electrical computer which used in modernised auto motives to maneuver its electronic modules. Gathering input from sensors and transmitting output to it's components, the automobile's computer alter the proper operation of the motor vehicle.

The ECU obtain data from the different components in the vehicle such as the camshaft and crankshaft sensors to smartly compute data such as line of fuel, cooling system, exhaust and some other internal components to determind and maneuver the driving state of the transmission, engine system such as the traction control (ABS), the ignition/injection timing, the airbags and so on.

A typical example is the speed sensor located on the wheel which detects the speed of the wheel and transfer the data to the ECM. This way, rather than sending signals to several wires from one sensor, the signals is being sent by the vehicle main computer to all the devices that need this data such as the suspension system, speedometer, ABS and so on.



On-board Diagnostics Port

OBD port A vehicle that accommodate ECU will also offer OnBoard Diagnostics (OBD) interface to let driver or officials to connect diagnostic equipage in order to diagnose and configure the vehicle computer module settings.





Vehicle computer module antitheft control

The car immobilized computer is theft avoidance system partition in the auto motive's computer. It bars the car engine from starting up unless driver is employing an authorized key. This infrastructure adopts a unique transponder chipped key that holds the electronic security pin-code or simply a password. The engine control unit does not start up the fuel injection system and the ignition cylinder if the PIN code in the key is different then the PIN code reserved in the immobilization system.



Various automakers use various types of car computers including the BCM (Brake Control Module), GEM (General Electric Module, PCM (Powertrain Control Module)) and others. Newer vehicle accommodate a few dosen ECUs and because of this development, the computing necessitate in configuring or resetting the motor vehicle's computer is turning much more challenging to maintain.
