All motor vehicles are different and required different parts and products one from the other. Older cars featured aspects such as window winders, no air-conditioning and carburettors as opposed to newer cars as seen on our roads today featuring fuel injection and many new nifty gadgets.
In order to operate these new features on cars such as Bluetooth controls, lane assist, parking sensors, airbags, breaking systems, AC, and virtually all electric components as well as some features within the engine, a car will need an Electric Control Unit (ECU). The ECU is programmed to operate these features and allow ease of use for the driver and technician.
When there are problems with the motor vehicle’s electronic components, the ECU will change certain settings as a way to safeguard the engine and other features on the car until the problem is fixed or the faulty part replaced. It can cause other inconvenient malfunctions to occur which range from simple to more intricate concerns. In order to avoid these issues regular servicing of the motor vehicle is of crucial importance.
How Does It Work?
In order to check that everything is in top working order the technician has to run a Computer Diagnostic Test on the vehicle. This is done by utilizing special tools to read and program the ECU of a motor vehicle. The computer diagnostic tools are plugged into the car and the technician will get to work re-programming the settings back to the way it should be so that the car resumes its regular electronic functions without malfunction.
To perform a computer diagnosis can be either a long process or a short one because the technician has to diagnose the actual problem and by doing the diagnosis, it can also help get an accurate reading.
