1. What is Car Diagnostic in UAE and Why Is It Important?

Car diagnostic in UAE involves using specialized tools and techniques to identify issues within a vehicle’s systems. According to a study by the Emirates Authority for Standardization and Metrology (ESMA), regular car diagnostics can reduce vehicle breakdowns by up to 30%. This process is crucial for maintaining the longevity, safety, and efficiency of your vehicle.

1.1. Understanding Car Diagnostic

Car diagnostic, also known as automotive diagnostics, is the process of identifying and troubleshooting problems in a vehicle using electronic diagnostic equipment. This equipment interfaces with the vehicle’s onboard computer systems to read diagnostic trouble codes (DTCs) and other data that can indicate malfunctions.

The primary goal is to pinpoint the exact cause of a problem, enabling accurate repairs. Modern vehicles are equipped with numerous sensors and electronic control units (ECUs) that monitor various systems, including the engine, transmission, brakes, and emissions. When a problem occurs, the ECU stores a DTC, which can be accessed using a diagnostic scan tool.
