1. Understanding OBD II Bluetooth Scanners

What exactly is an OBD II Bluetooth scanner? An OBD II Bluetooth scanner is a device that connects to your car’s On-Board Diagnostics II (OBD II) port and transmits data wirelessly to your smartphone or tablet via Bluetooth. This allows you to read diagnostic trouble codes (DTCs), monitor engine performance, and access various sensor data in real-time. According to a study by the University of California, Berkeley’s Department of Mechanical Engineering in March 2023, OBD II scanners can accurately diagnose up to 85% of common car problems, provided the user understands how to interpret the data.
