What Is Car ECU?

by What is car ECU The ECU is an electrical control unit which used in modern auto motives to alter its electric components. Collecting real time data from sensors and delivering output to the different module, the auto motive's computer alter the appropriate functioning of the vehicle.

The ECM gather information from the different digital units in the vehicle like the injector of fuel and camshaft sensors to effectively compute data as exhaust, intake, cooling system and several other components to determind and alter the sustaining working order of the transmission, engine system as the AC, the camshafts position, the fluid flow and others.

A simple illustration is the wheel speed detector which examine the car speed and transfer the data to the ECU. In this system, rather than distributing messages to number of components from one detector, the messages would be distributed by the automobile ECM to all the devices that need this data such as the ABS, speedometer, suspension system and others.



On-board Diagnostics Port

OBD port An automotive that incorporate vehicle computer system will also feather On-board Diagnostics (OBD) provision to enable driver or officials to connect diagnostics equipment and inspect the engine control unit settings.





ECU theft avoidance control

The car immobilized computer is theft opposing system placed on the engine control unit. It forestalls the ignition from starting unless using an accredited key. This mechanism uses an exclusive transponder chip key that holds the digital security pin or in other words a password. The engine control unit does not kindle the fuel injector system and the ignition cylinder if the pin-code in the key is different then the pin-code reserved in the immobilization system.



Different car makers use different types of ECUs including the PCM (Powertrain Control Module), BCM (Brake Control Module), ECM (Engine Control Module)) and more. Newer car accommodate several ECUs and with this development, the computing involved in resetting or configuring the engine control module is becoming more and more difficult to operate.
