What is Car ECU

14-09-2021 - The ECU is an electronic control unit which used in present day auto motives to maneuver its electronic components. Reading input from sensors and delivering output to the different module, the vehicle's computer manage the appropriate operation of the car.

The vehicle computer system gather data from other modules in the auto as the crankshaft and combustible system sensors to cleverly process information such as combustible fuel supply, intake, exhaust and several other internal components to assest and maneuver the operating condition of the transmission, engine system such as the lighting control, the body functions, the air bags etc.

A simple illustration is the speed sensor located on the wheel which calculate the car speed and transfer the information to the vehicle ECM. Using this infrastructure, instead of handing out signals to several modules from one detector, the signals would be delivered by the ECU to all the devices that makes use of this information such as the ABS, suspension system, speedometer etc.

On-board Diagnostics Port

An auto that was built with auto motive's computer will also feather On-board Diagnostics (OBD) outline to enable officials or driver to plug diagnostic equipage in order to retrieve and display the automotive ECM condition.

ECU antitheft control

The engine immobiliser is theft elimination mechanism built in the automotive ECU. It forbids the engine from igniting without employing an authorized key. This system adopts a unique transponder key that stores the digital security pin-code or plainly a password. The auto ECU wouldn't kindle the line of fuel system and the ignition cylinder if the pin-code in the key is not in sync with the pin-code reserved in the immobilized computer.

Various car makers use several types of ECUs like the BCM (Brake Control Module), GEM (General Electric Module, ECM (Engine Control Module)) and others. Contemporary automobile accommodate a few dosen ECUs and with this increasing complexity, the coding involved in configuring or resetting the engine control unit is becoming more and more challenging to maintain.
