8. Vianmääritys
If you encounter issues with your tail light converter, refer to the following troubleshooting guide:
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| No trailer lights functioning. | Loose or corroded connections; blown vehicle fuse; faulty trailer wiring. | Check all connections, vehicle fuses, and trailer wiring. Ensure a good ground connection. |
| Trailer lights not functioning correctly (e.g., brake lights activate with turn signal). | Incorrect wiring connections to the vehicle. | Re-verify all input wire connections to the vehicle's tail, stop, and turn signal wires. |
| Converter stops working intermittently or after a short circuit. | Integrated short circuit protection activated. | Disconnect the trailer. Inspect trailer wiring for shorts. The converter's protection is re-settable and should resume normal operation once the fault is cleared. |
| One specific trailer light not working. | Faulty trailer bulb; issue with trailer's internal wiring; specific output wire from converter is loose. | Check the trailer bulb. Inspect the trailer's wiring. Verify the corresponding output wire from the converter to the 4-flat connector. |
