What Is Car ECU?

by What is car ECU The motor vehicle's computer is a computerized control unit which used in modernised cars to maneuver its computerized components. Gathering data from sensors and transmitting output to the different module, the ECU manage the appropriate functioning of the vehicle.

The engine control unit collect information from other digital units in the vehicle like the pressure of fuel and camshaft sensors to smartly process information as exhaust, intake, fuel consumption and several other internal components to estimate and maneuver the driving working order of the engine, transmission system as the AC, the fluid flow, the body functions and so on.

A typical example is the speed detector found on the wheel which detects the car speed and transmits the information to the auto computer module. In this system, instead of handing out signals to several modules from one sensor, the signals is being transferred by the motor vehicle's computer to all the wired units that need this information as the ABS, suspension system, speedometer and so on.



On-board Diagnostics Port

The car immobilization computer is theft avoidance infrastructure partition in the ECM. It prevents the car engine from starting unless driver is applying an authorized key. This mechanism uses a unique chipped key that stores the electrical security PIN code or plainly a pass-code. The automotive ECM does not activate the pressure of fuel system and the ignition cylinder if the PIN code in the key is different then the PIN code reserved in the immobilizer.



Different car makers use other types of ECUs including the GEM (General Electric Module, PCM (Powertrain Control Module), BCM (Brake Control Module)) and others. Latest auto may contain several ECUs and because of this development, the programming necessitate in configuring or resetting the automotive ECM is becoming much more troublesome to control.
