This tester can test the trailer socket on the vehicle. It is used to directly test whether the trailer power supply wiring is normal or not. With LED indicators, it can indicate any fault on the wiring of the car or the trailer.

How to test the connection of a Trailer (can also be a caravan or bicycle carrier)
1. Put the plug in the connection of the tester.
2. Press the yellow button on the side of the tester.
3. If the wiring is good, all the LEDs light up. the function of each LED is (acc iso 1724):
left hand indicator (yellow);
fog light or 12V (blue);
mass (white);
right hand indicator (green);
right rear light (brown);
left brake light (red);
left rear light (black).
Attention: The pin no 2 can be used either for a warning fog lamp or a permanent 12V connection.
4. If a LED doesn't light up, it is because the corresponding wire is defective. If all the LEDs don't light up.
1. Put the tester in the socket of the car.
2. Press the yellow button on the side of the tester.
3. If the wiring is good, all the LEDs light up. Do again steps 4 as previous.
You can also test the functions of each pin of the socket.
