Automotive diagnostics refers to the process of identifying and troubleshooting issues in vehicles. This involves using specialized tools and equipment to read data from the vehicle's onboard computer systems. Technicians can detect problems related to the engine, transmission, brakes, and other critical components, ensuring the vehicle operates safely and efficiently. The diagnostics process often includes scanning for error codes that indicate specific malfunctions. Once the issues are identified, mechanics can recommend repairs or maintenance to restore the vehicle's performance. Regular diagnostics can help prevent more significant problems and extend the lifespan of the vehicle.
