What is the Motor Brain? What are their duties?

A powertrain control module (PCM), also known as an electronic control unit (ECU) or module (ECM), is an electronic system that regulates many of the vehicle's important functions and directly affects how well the vehicle operates.

PCM consists of electronic components designed on a multilayer circuit board. It is a powerful computer, often referred to as the brain of the engine control system, as it manages many different systems of the car, such as the engine's ignition, fuel injection, and emission systems, as well as the operation of the automatic engine. Its operation is in two modes, open loop and closed loop. Open loop runs in a preset schedule. Closed loop, on the other hand, is activated when the engine is cold using various sensors while running and occurs when the engine is at operating temperature.

The Powertrain Control Module (PCM) performs many functions in your car. It receives information from various engine sensors and with this information programmed into its memory, the PCM begins to generate output signals to control relays, actuators and solenoids. On the other hand, it sends a command to the fuel injectors that measures the appropriate amount of fuel. In short, throughout your entire driving journey, PCM automatically detects and corrects any changes to monitor the overall health of the car.

What is Motor Brain Control? How Does It Work?

It is located in the engine compartment of the car or in the passenger cabin. It is smaller in size than a car stereo. This small device contains several micro computers and provides the most accurate and smooth management of the engine under changing conditions while driving or at a standstill.

These microcomputers run the program contained in a chip.

This chip is responsible for the entire management and control of the engine, constantly checking the operating conditions of the engine, calculating the parameters and continuously adjusting the variables. Considering all these variables, it is repeated hundreds of times within a second. All these measurements are pressure, temperature, speed, air density, etc. operations are made possible by the fact that the variables are performed by hundreds of sensors in the engine with a deviation of one billionth.

Engine ECU Repair Process

The Ecutest brain test simulator produced by Nitro Mechatronics detects the exact location of the malfunction by checking all parts on the engine in case the electronic control units (ECU) used in the engines of the cars fail. Your action will be to detect the malfunction in the mixed brain system and repair this part. The process is so simple and professional.

Mercedes Euro 4, 5, 6 brain repairs are carried out in the Nitro Garage.
