What Is Car ECU?
by Tony Bell -
The vehicle's computer is an electrical control unit which used in modern cars to alter its electronic modules. Interpreting input from sensors and delivering output to the different components, the engine control module alter the proper functioning of the auto.
The auto computer module gather data from various digital units in the automotive such as the fuel injection and camshaft sensors to smartly compute data like cooling system, exhaust, intake and several other internal components to evaluate and alter the running circumstance of the transmission, engine system as the body functions, the camshafts position, the traction control (ABS) and more.
A simple example is the wheel speed detector which detects the speed of the wheel and send the data to the engine control module. This way, rather than sending signals to number of modules from one detector, the signals would be transferred by the engine control module to all the components that use this data as the ABS, speedometer, suspension system and more.
On-board Diagnostics Port
An automobile that incorporate engine control module will also provide OnBoard Diagnostics (OBD) interface to enable officials or driver to connect diagnostic equipage if you cleave to diagnose and configure the engine control module settings.
Vehicle's computer anti theft control
The car immobilization system is theft avoidance mechanism partition in the engine control unit. It accomplishes prevention of the engine from starting unless using an accredited key. This infrastructure adopts a unique transponder chip key that saves the digital security PIN code or simply a password. The auto motive ECM doesn't power on the consumption of fuel system and the ignition circuit if the pin-code in the key is different then the pin-code kept in the immobilizer.
Various vehicle makers use other types of ECUs such as the BCM (Brake Control Module), GEM (General Electric Module, ECM (Engine Control Module)) and others. Latest car accommodate many ECUs and because of this development, the programming entailed in configuring or resetting the engine control module is turning more difficult to operate.
