OBD2, or On-Board Diagnostics II, is a computer system integrated into modern vehicles to monitor emissions and diagnostic information. It plays a crucial role in detecting potential issues early, preventing costly damage to your vehicle. When a fault is detected, OBD2 provides detailed insights into its cause, including a snapshot of conditions leading up to the fault. Additionally, OBD2 offers real-time sensor readings such as vehicle speed, engine RPM, and torque, enabling calculations like fuel economy and usage.

OBD2 systems feature a 16-pin diagnostic connector located beneath the steering wheel on the driver’s side. Using a specialized tool known as a scan tool, you can access the OBD2 system in your vehicle. Scan tools come in two types: standalone handheld devices and PC/mobile-based tools. Standalone devices are portable but may lack advanced features and upgradeability, while PC/mobile-based tools leverage the power and flexibility of computers or mobile devices for comprehensive diagnostics.
