What is Car ECU - Okey DoKey Locksmith
The automotive ECM is a computerized control unit which used in modern vehicles to maneuver its electric components. Collecting input from sensors and delivering output to digital units, the auto motive computer control the appropriate operation of the vehicle.
The vehicle ECU gather inputs from several modules in the automotive like the crankshaft and pressure of fuel sensors to effectively process information as intake, exhaust, cooling system and several other components to determind and maneuver the sustaining working state of the transmission, engine system such as the body functions, the camshafts position, the lighting control and so on.
A typical example is the speed detector found on the wheel which examine the wheel speed and transfer the information to the ECM. Using this infrastructure, rather than sending information to multiple modules from one detector, the information would be distributed by the automobile computer to all the components that need this information like the suspension system, ABS, speedometer and so on.
On-board Diagnostics Port
An automotive that employ car main computer will also offer On Board Diagnostics (OBD) interface to enable driver or officials to plug diagnostic computer if you wish to retrieve and display the automobile computer system settings.
Automotive ECM antitheft control
The car immobilizer is theft elimination infrastructure partition in the engine control module. It forestalls the car engine from running unless driver is using an accredited key. This system uses a special transponder key that saves the electrical security PIN code or in other words a password. The motor vehicle's computer doesn't power on the fuel supply system and the ignition circuit if the PIN code in the key is different then the PIN code stored in the immobilization computer.
Various automobile manufacturers use other types of ECUs such as the ECM (Engine Control Module), BCM (Brake Control Module), GEM (General Electric Module) and others. Newer automotive may contain several ECUs and with this increasing complexity, the coding required in resetting or configuring the vehicle main computer is turning more and more difficult to handle.
