What Is Car ECU?
by Jimmy Dawson -
The automotive computer is a computerized control unit which used in modern motor vehicles to maneuver its electric components. Gathering input from sensors and transmitting output to the different module, the vehicle's computer alter the appropriate functioning of the car.
The auto's computer gather information from several digital units in the motor vehicle like the camshaft and crankshaft sensors to cleverly compute information like exhaust, intake, cooling system and a few other internal components to evaluate and maneuver the operating working order of the engine, transmission system as the traction control (ABS), the fluid flow, the airbags and so on.
A simple example is the wheel speed detector which calculate the car speed and transfer the information to the vehicle's computer. This way, instead of sending signals to several wires from one detector, the signals is being transferred by the automobile ECM to all the wired units that use this information such as the suspension system, speedometer, ABS and so on.
On-board Diagnostics Port
An auto that accommodate vehicle computer module will also outfit On-board Diagnostics (OBD) interface to enable driver or officials to connect diagnostics equipment to evaluate the motor vehicle computer system condition.
Automotive computer counter theft control
The engine immobilizer is theft countering system placed on the auto motive computer module. It bars the ignition from firing up unless using a commissioned key. This platform uses an exclusive transponder key that holds the electrical security pin-code or simply the password. The ECM will not activate the line of fuel infrastructure and the ignition switch if the code in the key is not in sync with the code kept in the immobilized computer.
Worldwide car-makers use various types of ECUs as the ECM (Engine Control Module), GEM (General Electric Module, PCM (Powertrain Control Module)) and others. Latest motor vehicle may contain a number of ECUs and because of this growing complexity, the coding necessitate in configuring or resetting the auto's computer is becoming way more challenging to operate.
