Keep the tester clean by wiping with a dry cloth, store it in its protective case, and avoid exposure to extreme conditions or moisture.

Ensure the tester is correctly and firmly plugged into the towing vehicle's socket. Verify the towing vehicle's electrical system is functioning and providing power to the socket.

Check that the correct function is selected on the tester. Ensure the towing vehicle's corresponding circuit is functional. If the vehicle's circuit is fine, the issue may lie within the trailer's wiring or the trailer's lights.

Inspect the connections at both the tester and the towing vehicle's socket for any signs of corrosion or damage. Ensure a solid connection.

Confirm that the tester is compatible with CANBUS systems (this model is). Ensure the tester is fully inserted. If problems persist, consult the vehicle's manual or a specialist.
