What Is Car ECU?
by Ben Hart -
The ECU is an electric computer which used in modern automobiles to alter its computerized components. Reading real time data from sensors and delivering output to digital units, the ECU alter the proper operation of the motor vehicle.
The auto motive computer system gather information from other digital units in the motor vehicle as the camshaft and crankshaft sensors to cleverly process data such as cooling system, exhaust, intake and several other internal components to estimate and alter the operating situation of the transmission, engine system as the fluid flow, the AC, the traction control (ABS) etc.
A common example is the speed sensor located on the wheel which calculate the speed of the wheel and transmits the data to the automobile main computer. This way, rather than sending signals to number of wires from one sensor, the signals is being sent by the ECU to all the devices that are interested in this data as the suspension system, speedometer, ABS etc.
On-board Diagnostics Port
A motor vehicle that accommodate auto computer module will also feather On-board Diagnostics (OBD) interface to enable driver or officials to connect diagnostics equipage and evaluate the auto motive ECM settings.
Auto motive computer module theft deter control
The car immobilization computer is theft countering instrument built in the vehicle ECU. It bars the engine from turning on unless employing a commissioned key. This mechanism adopts a unique transponder chipped key that holds the electrical security PIN code or in other words the password. The car main computer does not kindle the injection fuel system infrastructure and the ignition lock if the pin-code in the key does not match the pin-code reserved in the immobilization system.
Various automakers use different types of car computers including the BCM (Brake Control Module), ECM (Engine Control Module), PCM (Powertrain Control Module)) and others. Contemporary auto might have a few dosen ECUs and because of this growing complexity, the coding necessitate in resetting or configuring the vehicle computer is turning more challenging to handle.
