What is Car ECU

11-07-2020 - The ECU is an electric computer which used in modernised autos to maneuver its computerized modules. Interpreting real time data from sensors and transmitting output to digital units, the ECU manage the appropriate maneuvering of the auto.

The auto motive computer module obtain information from the different components in the vehicle such as the pressure of fuel and camshaft sensors to smartly compute information such as intake, cooling system, injection fuel supply and a few other internal components to estimate and maneuver the sustaining circumstance of the engine, transmission system like the air bags, the lighting control, the ignition/injection timing and so on.

A common illustration is the wheel speed detector which detects the car speed and send the information to the engine control unit. Using this infrastructure, rather than distributing messages to number of modules from one detector, the messages is being sent by the car's computer to all the devices that use this information such as the ABS, suspension system, speedometer and so on.

On-board Diagnostics Port

A vehicle that was built with vehicle's computer will also furnish OnBoard Diagnostics (OBD) provision to let driver or officials to connect diagnostics equipment to diagnose and configure the engine control unit condition.

ECU theft avoidance control

The car immobiliser is theft opposing system placed on the engine control unit. It forestalls the car from starting without using a registered key. This infrastructure uses a special transponder key that stores the electrical security pin-code or simply the pass-code. The vehicle ECM does not start up the combustible system system and the ignition cylinder if the pin-code in the key is different then the pin-code stored in the immobiliser.

Worldwide auto makers use different types of ECUs including the BCM (Brake Control Module), PCM (Powertrain Control Module), GEM (General Electric Module) and others. Newer motor vehicle accommodate a number of ECUs and because of this growing complexity, the programming entailed in resetting or configuring the automotive ECU is turning more challenging to control.
