What is Car ECU

29-03-2022 - The auto motive main computer is an electric computer which used in modernised vehicles to alter its computerized modules. Interpreting real time data from sensors and sending output to the different components, the automobile's computer alter the appropriate maneuvering of the auto motive.

The auto motive computer obtain information from several digital units in the automobile as the fuel supply and camshaft sensors to cleverly compute information such as intake, cooling system, combustible fuel supply and a few other internal components to determind and alter the running condition of the transmission, engine system as the air bags, the camshafts position, the fluid flow and others.

A typical illustration is the speed sensor located on the wheel which detects the car speed and transfer the information to the automotive computer system. This way, rather than distributing information to multiple wires from one detector, the information would be sent by the vehicle ECM to all the wired units that are interested in this information such as the ABS, suspension system, speedometer and others.

On-board Diagnostics Port

An auto that was built with ECU will also offer OnBoard Diagnostics (OBD) interface to let officials or driver to connect diagnostics equipment to inspect the ECM state.

Auto motive main computer theft elimination control

The engine immobilized computer is theft deter instrument placed on the engine control module. It prevents the engine from starting up unless utilizing an authorized key. This system uses an exclusive transponder chipped key that saves the electronic security pin or in other words the password. The vehicle ECU wouldn't turn on the pressure of fuel instrumentation and the ignition circuit if the pin-code in the key is not in sync with the pin-code reserved in the immobilization computer.

Various vehicle makers use various types of ECUs including the PCM (Powertrain Control Module), GEM (General Electric Module, ECM (Engine Control Module)) and others. Newer automobile may contain a number of ECUs and due to their development, the coding necessitate in configuring or resetting the motor vehicle ECU is turning more and more troublesome to maintain.
