What Is Car ECU?
by Eddie Rendal -
The engine control unit is an electric control unit which used in modernised motor vehicles to maneuver its electric components. Gathering real time data from sensors and sending output to digital units, the motor vehicle's computer control the proper maneuvering of the auto motive.
The automobile's computer gather inputs from other components in the auto motive as the fuel pump and crankshaft sensors to cleverly process information such as intake, cooling system, combustible fuel supply and several other internal components to evaluate and maneuver the running circumstance of the transmission, engine system like the camshafts position, the fluid flow, the airbags and more.
A common example is the wheel speed detector which examine the car speed and transfer the information to the engine control unit. This way, instead of handing out messages to number of components from one sensor, the messages would be distributed by the motor vehicle computer system to all the devices that use this information like the speedometer, ABS, suspension system and more.
On-board Diagnostics Port
An automotive that accommodate ECU will also arrange On Board Diagnostics (OBD) interface to let officials or driver to connect diagnostics equipment and diagnose and configure the vehicle main computer state.
Engine control unit counter theft control
The engine immobilization computer is theft countering mechanism placed on the auto motive main computer. It forbids the ignition from igniting unless driver is using an accredited key. This platform uses a special transponder chip key that stores the digital security pin-code or simply a passcode. The auto motive main computer doesn't power on the fuel injector instrumentation and the ignition switch if the pin-code in the key is different then the pin-code kept in the immobilized computer.
Different automakers use different types of car computers like the PCM (Powertrain Control Module), GEM (General Electric Module, BCM (Brake Control Module)) and more. Newer car may contain a number of ECUs and with this increasing complexity, the programming required in resetting or configuring the automotive computer is turning more troublesome to control.
