3. Bluetooth connection issue

Please check the following:

• OS Version: Ensure your device's OS version is compatible. The scanner is compatible with Android 4.4+ (with 64-bit processor) and iOS 11+. Android devices with 32-bit processors may not be compatible.
• Dongle Connection: Make sure the dongle is firmly plugged into the OBDII port.

The software for some new or rare vehicles may not be developed yet. Please send the S/N of your device and the vehicle information/VIN to check compatibility.

10. It cannot read codes. I have lights on the dashboard.

AD20 Pro can read codes in all available systems. AD20 can only read codes related to OBD2. For further assistance, please contact support with your S/N and vehicle information/VIN.

11. It cannot clear the codes.

AD20 Pro can clear codes in all available systems. AD20 can only clear codes related to OBD2. Some codes can only be cleared after the faults are eliminated, as this affects driving safety.

12. There is no trouble light on the dashboard, but the code cannot be cleared.

If the code starts with "U", it indicates a communication state and does not require worry. If further assistance is needed, send the S/N and a screenshot of the code.

13. I have repaired the vehicle, but the code still cannot be cleared.

The code will disappear automatically when the ECU detects no faults after a driving cycle, provided the vehicle is truly repaired. Do not worry if the fault is eliminated.

14. Speed/Water temp/oil volume is not accurate because it is different from those on the dashboard.

There might be slight adjustments in live data streams due to vehicle settings. Verify with other scanners. If inaccuracies persist, contact tech support with your S/N and vehicle information/VIN.

15. Cannot read O2 sensor data.

O2 sensor data can generally be accessed via the "O2S Monitoring Test" under the "OBD2" menu. If unavailable, the vehicle may not be configured to send O2 sensor data to the ECU. Contact support with your S/N and VIN for verification.

16. There is no diagnostic reports after scanning.

Diagnostic reports are not included due to product design and cost. A feature to convert data streams to CSV is expected in the future.

17. Can I select the live data streams freely?

This feature is currently only available on Anyscan series and diagnostic tablets.

18. The battery of my car is dead after using the AD20 for a long time.

Reason 1: Low battery may cause multiple fault lights, often indicating low voltage. These can be cleared without affecting vehicle use.

Reason 2: Some vehicles' OBD2 ports may not enter sleep mode even with the ignition off, draining the battery. In such rare cases, unplug the device when not in use. If no power consumption is detected, it can be plugged in permanently.
