5. Troubleshooting
Common Issues and Solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not connecting via Bluetooth. | Bluetooth is off on the mobile device; adapter not properly plugged in; vehicle ignition is off. | Ensure Bluetooth is enabled on your phone/tablet. Check that the adapter is securely plugged into the OBD2 port. Turn the vehicle ignition to the ON position. Restart the ThinkDiag app. |
| Cannot clear fault codes. | The fault is due to a hardware defect in the vehicle; the underlying issue has not been resolved. | Note: If a fault code cannot be cleared, it indicates a persistent hardware defect in the car. The OBD2 scanner will not remove the error code until the corresponding hardware defect in the vehicle is repaired. Address the physical issue first. |
| App crashes or freezes. | Outdated app version; insufficient device memory; software conflict. | Ensure the ThinkDiag app is updated to the latest version. Close other background applications on your mobile device. Restart your mobile device. |
| Inaccurate readings or incomplete scans. | Incorrect vehicle profile selected; outdated vehicle software. | Verify that the correct vehicle make, model, and year are selected in the app. Download and install the latest vehicle-specific software updates. |
