What is Car ECU

15-09-2021 - The engine control unit is an electric computer which used in present day motor vehicles to maneuver its electric modules. Collecting real time data from sensors and sending output to digital units, the motor vehicle's computer manage the proper functioning of the car.

The engine control unit collect data from various digital units in the auto motive such as the injection system and crankshaft sensors to smartly compute information like intake, injection fuel supply, cooling system and a few other internal components to determind and maneuver the driving state of the transmission, engine system like the AC, the lighting control, the fluid flow and more.

A simple illustration is the speed detector found on the wheel which examine the car speed and send the information to the motor vehicle computer system. With this model, rather than handing out signals to number of modules from one detector, the signals is being transferred by the engine control module to all the devices that use this information such as the suspension system, speedometer, ABS and more.

On-board Diagnostics Port

A motor vehicle that employ auto ECM will also provide OnBoard Diagnostics (OBD) interface to enable driver or officials to plug diagnostic computer if you want to diagnose the motor vehicle computer module settings.

Engine control unit counter theft control

The engine immobiliser is theft countering mechanism built in the vehicle computer module. It forestalls the car from flaring up unless applying an authorized key. This platform uses a unique transponder key that holds the electronic security pin or plainly a password. The ECM wouldn't kindle the fuel system instrumentation and the ignition cylinder if the code in the key does not match the code kept in the immobilized computer.

Different auto manufacturers use several types of ECUs like the PCM (Powertrain Control Module), GEM (General Electric Module, ECM (Engine Control Module)) and more. Contemporary auto motive might have a number of ECUs and due to their increasing complexity, the coding involved in configuring or resetting the ECM is turning much more challenging to operate.
