What is a Universal Car Fault Diagnostic Code Reader OBD2?
OBD2 stands for On-Board Diagnostics, generation 2. It’s a standardized system found in almost all vehicles manufactured after 1996 (1994 for gasoline cars in the US). The OBD2 system continuously monitors your car’s engine, transmission, and emissions systems, looking for any malfunctions.
When a problem is detected, the OBD2 system generates a specific code, known as a DTC, and stores it in the car’s computer. A universal car fault diagnostic code reader OBD2 acts as the interpreter, translating these codes into understandable information.

Common Car Fault Diagnostic Codes
While a universal car fault diagnostic code reader OBD2 will provide you with a definition for each DTC, here are a few common codes and what they generally indicate:
