1. Introduction
The ANCEL AD310BT is a versatile automotive diagnostic tool that combines the functionalities of an OBD2 scanner and a battery tester. It allows users to read and clear engine fault codes, view live data, perform various diagnostic tests, and check battery health directly from their smartphone via Bluetooth. This manual provides detailed instructions for setting up, operating, and maintaining your AD310BT device.

4. Maintenance
4.1 Software Updates
The ANCEL AD310BT supports lifetime free software updates. Ensure your device and app are always running the newest software version for optimal performance and compatibility with the latest vehicle models and diagnostic protocols. Check the Ancel APP regularly for update notifications.
4.2 General Care
- Keep the device clean and free from dust and moisture.
- Store the device in a cool, dry place when not in use.
- Avoid dropping the device or subjecting it to strong impacts.
- Do not attempt to disassemble or modify the device, as this will void the warranty.
5. Troubleshooting
If you encounter issues with your ANCEL AD310BT, refer to the following common troubleshooting tips:
- Device not powering on: Ensure the device is securely plugged into the vehicle's OBD2 port. Check the vehicle's battery for sufficient power.
- App not connecting via Bluetooth: Verify Bluetooth is enabled on your smartphone. Restart both the app and the AD310BT device. Ensure no other devices are actively connected to the scanner.
- Unable to read codes: Confirm the vehicle's ignition is in the ON position (engine off or running, depending on the test). Ensure the vehicle is OBD2 compliant (most vehicles from 1996 onwards in the US, and newer in other regions).
- Engine Light remains on after clearing codes: Some fault codes may require multiple drive cycles to clear, or the underlying issue has not been resolved. Address the root cause of the fault before attempting to clear codes again.

Figure 8: Understanding why the engine light turns on and how to diagnose it.
- Inaccurate battery test results: Ensure the battery clamps (if using an external battery tester, though AD310BT uses OBD2 for battery check) are clean and securely connected. The AD310BT's BAT check function is primarily for voltage detection for 12V vehicles and results are for reference.
