Testing the steerer

Insert a 9V battery (not included) into the battery compartment of the tester in the correct direction. Connect the tester to the trailer plug . In the case of a 13-pin connector, a 13-pin to 7-pin adapter (included) must be placed between the vehicle and the plug.

Press the test button on the side. If the trailer is equipped with all functions (signalling, reversing light, brake light and rear fog light), the corresponding lights should illuminate when the test button is pressed. Please note that not all trailers/trailers are equipped with a fog light and/or a mars marshalling light. In this case the corresponding indicators will not illuminate. Only use this function when testing a stecher!
