Hi Guys
I just bought a 2010 GLK 350 last week with OEM tow package and this week end I have check if all the current was there on the 7 pins connector before hooking a trailer ,but I notice that I may have a problem.


when I check with a 12v test light the parking light only blink and does not stay on, the Right turn does not blink too


I have current on the pin that says "positive" and the Left turn work (test light blink like the Left turn on the GLK light)


I did not test brake I was alone so


can somebody help me!
Thanks

You need to hook up the trailer - CanBus will only activate the full connector with trailer attached (or with comparable electrical load).

it does the same with trailer connected....I have LED light, I saw that could be a problem too because it does not draw enought current....can it be program for LED??
