Problems Pairing the Prodigy RF Brake Controller with a 2010 Porsche Cayenne


Have tried several things to get the remote paired. Im stuck. When I plug it into my Cayenne the remote flashes N.C. yes the 7pin from the trailer is NOT connected to the Protigy unit at this time So after some reading I tried parking a 2008 Chev PU next to it and plugged the unit into the Chev. Same problem. After calling tech support I tried taping off the pin in the 5 oclock position on the back of the unit and plugging the trailer in and connect to vehicle, guess this is to trick the Cayenne into turning on its trailer power pin at the 1 oclock position. No luck! SO I understand that the pin at the 1 oclock position on the tow vehicle needs to have power to program the unit and Porsche / WV etc. are funny about that working without resistance on that circuit. No problem I ran a jumper wire to the pin at the 1 oclock on the Porsche to make sue it had full power. Still see N.C. when I plug the remote in! Hmmm stumped so I finally check the Cayennes pin at the 1 oclock with the vehicle running and it indeed has power, thus maybe no power jumper is needed anyway. So I plug in the Protigy unit to the Vehicle and check the 1 oclock pin on the unit itself. Yup it has constant power too. So Im thinking the Protigy unit has its needed power but……. Where do I go from here. Thanks

When you are trying to pair the Prodigy RF brake controller, # 90250, sometimes the display does not read what the instructions say it should read. What happens for most people is they stop and start over or try to figure out what went wrong. What you will want to do though is just keep going through the installation steps as if it did read what the instructions say it should.

There is also an issue on German made vehicles with the factory 7-Way and bulb out sensors. It does not sound like you have this issue, especially if the trailer does not have LED lights and based on what you have tried thus far. But if all else fails that could be the problem and you would need a special adapter, # 20142.

Usually pairing it with another vehicle parked next to the intended vehicle works. But to me it sounds like the first recommendation I made will be the solution.
