4 Easy Testing Steps with the AutoTest Trailer Socket Tester
Insert the 7pin plug (or 13pin adapter) into the Trailer socket at the rear of the vehicle.
Holding the handset return to the vehicle driver’s seat.
Ensuring the vehicle is in a stationary position, with the gears in neutral and the hand brake on. Turn on ignition.
Without touching the self-test button, by activating the relevant control (for example the tail lamp) the corresponding lamp on the test device will illuminate, giving a positive indication of the continuity of the output. This should be repeated for all six controls. If one or more lights fail to illuminate this indicates a fault with the continuity of output from one or more of the pins.
