What Is Car ECU?
by Garry Fulton -
The ECU is an electrical computer which used in modern motor vehicles to manage its computerized modules. Reading data from sensors and sending output to it's components, the motor vehicle main computer control the proper maneuvering of the motor vehicle.
The vehicle ECM obtain data from other components in the motor vehicle like the line of fuel and camshaft sensors to cleverly process data such as intake, pressure of fuel, cooling system and several other internal components to assest and manage the sustaining scenario of the transmission, engine system as the lighting control, the fluid flow, the AC and more.
A common example is the speed detector found on the wheel which calculate the wheel speed and transfer the data to the ECM. Using this infrastructure, instead of handing out signals to number of modules from one detector, the signals would be distributed by the engine control unit to all the devices that use this data like the speedometer, ABS, suspension system and more.
On-board Diagnostics Port
A vehicle that accommodate engine control unit will also provide On-board Diagnostics (OBD) provision to enable driver or officials to connect diagnostic computer and retrieve and display the automobile main computer settings.
ECU theft avoidance control
The car immobilization system is theft avoidance system placed on the vehicle computer. It forestalls the car engine from running without utilizing a certified key. This platform employs an exclusive transponder key that holds the electrical security PIN code or simply the pass-code. The automobile computer module will not start up the fuel injector instrumentation and the ignition cylinder if the pin-code in the key does not match the pin-code reserved in the immobilization computer.
Different car makers use various types of car computers including the BCM (Brake Control Module), ECM (Engine Control Module), GEM (General Electric Module) and more. Latest vehicle may contain many ECUs and due to their increasing complexity, the programming required in resetting or configuring the ECM is turning way more difficult to handle.
