8. مسئلا حل ڪرڻ
If you encounter issues while using your FOXWELL devices, refer to the table below for common problems and their solutions.
| مسئلو | حل |
|---|---|
| ڊوائيس تي طاقت نه آهي. | For BT301: Ensure battery clamps are securely connected to the correct battery terminals. For NT630 Plus: Verify the OBDII cable is firmly connected to the vehicle's DLC and the ignition is ON. Check vehicle's fuse for the OBDII port. |
| NT630 Plus fails to link with vehicle. | Confirm the vehicle's ignition is ON. Check if the OBDII cable is properly connected. Ensure the vehicle is OBDII compliant (most vehicles from 1996 onwards). Try connecting to a different OBDII compliant vehicle to rule out device issue. |
| BT301 shows 'Battery Error' or inconsistent results. | Ensure battery terminals are clean and free of corrosion. Verify that the correct battery type and CCA rating were entered. Ensure a stable connection of the battery clamps. |
| Cannot clear DTCs with NT630 Plus. | Ensure the ignition is ON and the engine is OFF. If the underlying fault is still present, the codes will reappear immediately. Address the root cause of the DTCs first. |
| اسڪرين منجمد آهي يا غير جوابده آهي. | Disconnect the device from the vehicle/battery, wait a few seconds, and reconnect. If the issue persists, perform a software update if available. |
