Procedure
Vehicle side
1. Plug the lead from the testing box into the towing vehicle trailer socket.

vehicle is not wired in accordance with ISO/DIN standards.
3. Now get into the car (driver's side) with the testing box and check the trailer socket cable connections by
calling up the various functions (lights, brakes, blinkers etc.).
4. Faults/omissions in the wiring will be shown up by failure of the LEDs to light up, or an incorrect LED lighting
up.
Trailer side
1. Plug the trailer plug in the socket on the rear of the testing box (in the case of 7-pole plugs, please use the
adapter).
2. Place the pushbutton cell supplied in the battery holder (on the rear of the testing box).
