Testing the best OBD2 scanners involves connecting each scanner to a vehicle’s OBD-II port, ensuring it can report the car’s vehicle identification number (VIN). Wireless scanners are connected to devices via Bluetooth or Wi-Fi, while handheld scanners are plugged into the OBD-II port for power. The engine and vital systems are monitored, and the scanner’s details are checked before fixing any problems and erasing the error code.

12.1. Testing Procedures

The testing procedures include:

• Connecting to the OBD-II Port: Ensuring the scanner properly connects and reports the VIN.
• Wireless and Handheld Testing: Evaluating connectivity and ease of use for both types of scanners.
• Monitoring Engine Systems: Observing live data and identifying potential issues.
• Fixing and Erasing Error Codes: Verifying the scanner’s ability to clear error codes after repairs.

12.2. Interpreting Fault Codes

All fault codes consist of four numbers and a letter prefix, indicating the system affected. Generic codes apply to all cars, while others are specific to individual carmakers. For example, a P0098 code indicates an issue with the engine’s intake air temperature sensor, while a P1112 code on a Ford indicates intermittent values from the intake air temperature sensor, requiring replacement.
