❓WHAT IS CAR CODE READER

A Car Code Reader is a specialized diagnostic tool that connects to a vehicle's onboard computer system through the OBD (On-Board Diagnostics) port to retrieve and interpret error codes generated when the vehicle's systems detect a malfunction.

Modern vehicles contain numerous electronic control units (ECUs) that constantly monitor everything from engine performance to safety systems, generating specific fault codes when parameters fall outside acceptable ranges. These handheld devices range from basic models that simply read and clear engine-related codes to sophisticated scanners that access multiple vehicle systems, display real-time data, and offer advanced service functions. The technology evolved significantly after 1996 when the OBD2 protocol became standardized across all vehicles sold in the United States, creating a common diagnostic language.
