Understanding OBD2 and Your Car’s Secret Language

Every car manufactured after 1996 speaks a universal language – OBD2, short for On-Board Diagnostics, version 2. This system acts as your car’s internal communication network, constantly monitoring various systems and components. When something goes wrong, the OBD2 system stores a specific code in your car’s computer, indicating the nature of the problem.

An Android phone OBD2 scanner acts as the interpreter between you and your car’s onboard computer. By connecting wirelessly via Bluetooth or WiFi, the scanner retrieves these diagnostic trouble codes (DTCs) and translates them into plain English, giving you valuable insights into your car’s health.
