What is Car ECU

23-12-2024 - The ECU is an electronic computer which used in modernised motor vehicles to manage its computerized components. Collecting data from sensors and sending output to it's components, the auto computer control the appropriate operation of the auto motive.

The ECU collect inputs from the different digital units in the auto motive as the crankshaft and camshaft sensors to cleverly compute data as fuel injection, exhaust, intake and some other components to assest and manage the driving situation of the transmission, engine system such as the fluid flow, the camshafts position, the AC and more.

A simple illustration is the speed sensor located on the wheel which examine the car speed and send the data to the auto ECU. Using this infrastructure, instead of distributing messages to number of wires from one detector, the messages is being delivered by the engine control module to all the devices that are interested in this data such as the ABS, speedometer, suspension system and more.

On-board Diagnostics Port

An automobile that employ ECM will also offer On Board Diagnostics (OBD) port to enable driver or officials to plug diagnostics equipage if you need to diagnose and configure the vehicle ECU settings.

ECU theft deter control

The engine immobilization system is anti theft instrument placed on the automotive's computer. It forestalls the ignition from running without utilizing an accredited key. This system uses a unique transponder key that stores the digital security pin or plainly a pass-code. The auto's computer wouldn't kindle the fuel pump system and the ignition switch if the code in the key does not match the code stored in the immobilized computer.

Different car manufacturers use various types of ECUs like the PCM (Powertrain Control Module), ECM (Engine Control Module), BCM (Brake Control Module)) and others. Latest vehicle accommodate many ECUs and due to their increasing complexity, the computing necessitate in resetting or configuring the motor vehicle ECU is turning more and more challenging to handle.
