Car Diagnostic Test at Smile Servicing & Repairs

All modern cars now have a computer system that checks the engine, brakes and almost every mechanical part on the car. Therefore, this computer system is constantly updating information from the different sensors in the engine. Adjusting these as needed will ensure your car always runs smoothly with no problems. Hence, this computer system also controls the engine management light on the dashboard.

When there is a problem that the computer cannot fix itself, it triggers the light so a garage can then identify and solve the problem. A code is produced by the system to identify the problem and is stored by the onboard diagnostics system. This system allows for a garage to use a scanning tool to identify the problem on nearly all makes of cars. If you notice one of these warning lights, book car diagnostics in Portsmouth with Smile Servicing & Repairs today.

How Does a Car Diagnostic in Portsmouth Work?

Inserting a scanner into the computer’s connector, usually located under the dashboard or behind the glovebox, is the initial step in carrying out a diagnostic test. Once the vehicle information has been inputted, the car’s model, vehicle identification number (VIN), and engine type are entered into the scanner. It can then identify the diagnostic fault code. It is this code that helps us to know where to look to find the problem. A car diagnostic can make finding an engine management problem much easier. As a result of this, instead of having to carry out a complete engine check, our state-of-the-art Bosch diagnostic equipment can do it for us.

A diagnostic problem code is outputted as a set of numbers and letters. These codes are read by the diagnostic scanner which is transmitted by a vehicle’s on-board diagnostics (OBD) system. Nearly all vehicles made after 1996 comes equipped with an OBD computer. So, vehicles are capable of relaying thousands of diagnostic trouble codes to any garage with the equipment to read them.
