7. Troubleshooting
If you encounter issues with your TKSTAR GPS tracker, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Tracker is offline/No signal | SIM card issues (no credit, no data, incorrect insertion), poor network coverage, device power off. | Check SIM card balance and data plan. Reinsert SIM card. Move vehicle to an area with better network coverage. Check power connections. |
| Inaccurate positioning | Weak GPS signal (e.g., underground parking, dense urban areas), reliance on LBS. | Move vehicle to an open area with clear sky view for better GPS signal. Understand that LBS positioning is less accurate (100-1000m). |
| Alarms not working | Alarm settings not configured, authorized numbers not set, power issues. | Verify alarm settings in the app/platform. Ensure authorized numbers are correctly saved. Check power supply. |
| Remote control not responding | Remote battery low, out of range, interference. | Replace remote battery. Ensure you are within effective range. Avoid areas with strong radio interference. |
| Engine cut-off not working | Incorrect wiring of relay, wrong SMS command, tracker offline. | Verify relay wiring with a professional. Double-check SMS command format and password. Ensure tracker is online. |
