What Is Car ECU?

by What is car ECU The automotive computer system is a computerized control unit which used in modern auto motives to manage its computerized modules. Interpreting data from sensors and sending output to it's components, the vehicle ECM control the appropriate operation of the automotive.

The vehicle computer system collect data from several modules in the auto like the camshaft and fuel system sensors to cleverly process information like cooling system, intake, exhaust and several other components to assest and manage the operating scenario of the engine, transmission system like the camshafts position, the ignition/injection timing, the air bags etc.

A common illustration is the wheel speed detector which calculate the car speed and send the information to the automobile's computer. Using this infrastructure, rather than distributing information to multiple components from one sensor, the information would be transferred by the auto's computer to all the wired units that are interested in this information as the ABS, speedometer, suspension system etc.

On-board Diagnostics Port

OBD port A vehicle that employ auto motive ECM will also provide On-board Diagnostics (OBD) outline to let officials or driver to connect diagnostic computer to evaluate the automobile main computer condition.

Automotive computer system antitheft control

The engine immobilized computer is theft countering infrastructure placed on the automobile computer system. It forestalls the engine from flaring up unless using a certified key. This mechanism uses a unique transponder chip key that holds the digital security pin or plainly a passcode. The motor vehicle main computer does not kindle the fuel system instrumentation and the ignition lock if the code in the key is different then the code kept in the immobilized computer.

Different automobile manufacturers use various types of ECUs like the PCM (Powertrain Control Module), BCM (Brake Control Module), ECM (Engine Control Module)) and others. Latest auto might have several ECUs and because of this development, the programming required in configuring or resetting the ECM is becoming more difficult to maintain.
