What Is Car ECU?
by Corry Williams -
The automobile ECM is an electric computer which used in modernised vehicles to maneuver its computerized components. Reading real time data from sensors and sending output to it's components, the automobile computer module control the proper functioning of the auto.
The ECM obtain data from various modules in the motor vehicle as the fuel supply and crankshaft sensors to effectively process data as combustible system, exhaust, cooling system and several other components to determind and maneuver the running working order of the transmission, engine system such as the ignition/injection timing, the lighting control, the body functions and more.
A simple illustration is the speed sensor located on the wheel which examine the wheel speed and transmits the data to the automotive ECU. Using this infrastructure, instead of handing out information to several wires from one sensor, the information is being distributed by the vehicle's computer to all the devices that makes use of this data such as the suspension system, ABS, speedometer and more.
On-board Diagnostics Port
A motor vehicle that incorporate ECU will also furnish On Board Diagnostics (OBD) interface to let officials or driver to plug diagnostics computer to examine the motor vehicle computer state.
Automobile ECM theft avoidance control
The car immobilization system is theft countering system placed on the vehicle ECU. It accomplishes prevention of the car from kindling unless using an authorized key. This system uses an exclusive chipped key that stores the digital security PIN code or in other words a passcode. The automotive ECM wouldn't kindle the fuel supply infrastructure and the ignition switch if the pin-code in the key does not match the pin-code stored in the immobilization computer.
Different vehicle producers use various types of ECUs as the PCM (Powertrain Control Module), ECM (Engine Control Module), GEM (General Electric Module) and others. Contemporary car may contain a number of ECUs and due to their development, the computing involved in resetting or configuring the engine control module is turning more challenging to maintain.
