What is Car ECU

04-05-2020 - The engine control module is a computerized computer which used in modernised cars to alter its electric components. Gathering data from sensors and sending output to it's components, the auto computer module control the appropriate functioning of the auto.

The automobile's computer collect inputs from the different modules in the car such as the line of fuel and camshaft sensors to cleverly process information like intake, fuel consumption, exhaust and several other internal components to evaluate and alter the running condition of the transmission, engine system as the camshafts position, the traction control (ABS), the AC and others.

A simple illustration is the speed sensor located on the wheel which calculate the car speed and transfer the information to the ECU. Using this infrastructure, instead of sending signals to number of components from one detector, the signals would be transferred by the engine control module to all the components that are interested in this information as the suspension system, speedometer, ABS and others.

On-board Diagnostics Port

A car that accommodate vehicle's computer will also arrange OnBoard Diagnostics (OBD) provision to let officials or driver to plug diagnostic equipage and retrieve and display the ECM condition.

Engine control module theft countering control

The engine immobilization system is theft opposing system placed on the engine control module. It forestalls the engine from flaring up without using an accredited key. This system uses a unique transponder chip key that holds the electrical security code or plainly the password. The vehicle's computer doesn't light up the fuel injection instrumentation and the ignition cylinder if the code in the key does not match the code stored in the immobilizer.

Worldwide auto manufacturers use other types of car computers including the PCM (Powertrain Control Module), BCM (Brake Control Module), GEM (General Electric Module) and more. Newer auto might have many ECUs and due to their development, the coding necessitate in configuring or resetting the ECU is turning much more troublesome to maintain.
