What is Car ECU

15-09-2019 - The auto ECM is an electronic computer which used in present day motor vehicles to alter its electronic components. Gathering data from sensors and delivering output to it's components, the auto motive computer alter the proper functioning of the automotive.

The vehicle computer gather information from other components in the car such as the camshaft and crankshaft sensors to cleverly process data as cooling system, exhaust, fuel consumption and a few other components to assest and alter the sustaining scenario of the engine, transmission system as the traction control (ABS), the fluid flow, the airbags etc.

A typical illustration is the speed detector found on the wheel which calculate the car speed and send the data to the automotive computer module. This way, rather than sending signals to multiple wires from one sensor, the signals is being delivered by the automotive ECU to all the wired units that use this data such as the speedometer, ABS, suspension system etc.

On-board Diagnostics Port

An automotive that was built with automotive ECM will also offer On Board Diagnostics (OBD) provision to enable driver or officials to plug diagnostics equipment and diagnose the motor vehicle computer system settings.

Auto ECM theft deter control

The engine immobilization computer is anti theft instrument built in the automotive computer system. It prevents the car from firing up unless driver is employing a certified key. This platform adopts an exclusive transponder chip key that stores the digital security PIN code or plainly a password. The ECM will not kindle the line of fuel instrumentation and the ignition cylinder if the PIN code in the key does not match the PIN code reserved in the immobilization computer.

Different manufacturers of automobiles use several types of car computers including the BCM (Brake Control Module), ECM (Engine Control Module), GEM (General Electric Module) and others. Contemporary motor vehicle accommodate several ECUs and because of this growing complexity, the computing necessitate in resetting or configuring the automobile main computer is becoming more and more difficult to handle.
