FAQ

1) Does AD20 support my car?

Advancer AD20 supports most vehicles using standard OBD-II protocols. Refer to "Specifications - Supported protocols" for details.

2) Can AD20 be plugged in the vehicle all the time?

Yes, AD20 will not cause battery drain or damage during daily driving. It uses low-power Bluetooth and automatically sleeps after the car is off for 3 minutes, waking up when the car is turned on.

3) Why can't I connect to my AD20?

1. Ensure the "Advancer" app is allowed to turn on Bluetooth, access location, and device storage.
2. Make sure the AD20 is firmly connected to the OBD-II port.
3. Verify you are using the latest version of the app from a reliable source.

4) Why can't I communicate with the vehicle?

1. Ensure the engine is turned on and idling.
2. Verify the vehicle brand and model registered in the Advancer app are correct.

5) How can I do when the device cannot sign up or log in?

Check your phone's network connection and ensure your account information is correct. If issues persist, contact customer support.

6) Why do fault codes reappear after clearing?

1. When clearing codes, consider the actual fault situation. Sporadic codes (due to interference, vibration, poor contact) can usually be cleared directly.
2. Actual codes indicate component failure. Fix the underlying issue before clearing. If fault lights return, further inspection is needed.

7) Why are there DTC codes but no dashboard lights?

1. Manufacturers determine which DTCs trigger dashboard warning lights.
2. The ECU might not have fully confirmed a fault yet, possibly due to interference or vibration. The ECU typically confirms faults after several operating cycles.

8) Why are there dashboard fault lights but no DTC codes found by Advancer?

Confirm Advancer's diagnostic capabilities: AD20 supports OBDII Standard fault codes & Engine in-depth check; AD20 Pro supports OBDII Standard fault codes & All system in-depth check. For example, AD20 Pro can read ABS fault codes that AD20 might not.

9) Why does the fault light turn on during diagnosis?

Some ECUs enter a diagnostic mode during the process, causing the corresponding fault light to illuminate. This is normal and the light will turn off automatically once the diagnosis is complete.
