  • Pairing Problems with the Tekonsha Prodigy RF Brake Controller and a 2008 BMW X5
  • There are very precise steps that you must take to make sure the RF brake controller, # TK94FR, will pair with the hand held unit. First, make sure the trailer is coupled to the towing vehicle. Then plug the RF into the tow vehicle connector making sure the trailers connector is not connected to the RF yet. Next, start the tow vehicle engine and then plug the hand-held unit into the auxiliary power port. Turn the power knob until the display reads a flashing 0.0. Then, press and hold both...

  • Prodigy RF Brake Controller is Not Pairing with a 2014 BMW X5
  • The issue you are having is common for German vehicles. There are a few things you can try to get the unit to pair. First, If you do not see displayed what the instructions say just keep going through the steps. Sometimes, it will not display what it is supposed to but it will still work if you go through the steps to completion. If that does not work then you can try taping off the pin in the 5 oclock position at the back of the RF (where the trailer plugs into) using electrical tape....

  • Tekonsha Prodigy RF Brake Controller Flashing N.C. When Trailer Re-Hitched
  • Based on my research, a "n.c." display that flashes continuously on the Tekonsha Prodigy RF # TK94FR most commonly indicates that there is no power to the controller's Power Module. I recommend testing your vehicle's trailer connector with a circuit tester, like # 40376, to ensure that there is power at the socket. On your vehicle's trailer socket, the 12V power pin should be located in the 1 o'clock position. If there is no power reaching the trailer socket, you will want to check the...

  • How to Stop Parking lights Pulsing on a Trailer With LED Lights
  • This can be a fairly common issue with trailers that have LED lights being towed with a vehicle that also uses LED lights. The higher amperage being pushed through the wiring harness can cause lights to pulse and is usually a pretty easy fix. Multiple lights are generally installed to a trailer with a single ground source. With your situation, you will need to have a dedicated ground for each light. This should cause the run off to dissipate into the frame and solve the pulsing issue.

  • No Reverse Light Circuit When Towing with a 2017 BMW X5
  • I looked up your order and saw that you have purchased both the ZCI Circuit Protected Vehicle Wiring Harness part # 119250KIT and the Universal Installation Kit for Trailer Brake Controller part # ETBC7. The ZCI kit as you mentioned will not require any cutting or splicing. However, the 4-way included in this kit does not have a circuit for the reverse lights. The reverse light circuit is obtained through the 7-way trailer connector with the purple wire. The purple wire from the 7-way on...

  • Troubleshooting Shorted Out Powered Taillight Converter on 2007 BMW X5
  • The converter is designed to provide circuit protection, to isolate any shorts from the vehicle wiring. In this instance, it served its purpose perfectly by blowing its internal circuit breaker before anything on the vehicle could be damaged. The circuit breaker shuts down before the short can reach the vehicle wiring, which explains why no fuses were blown. Before replacing the converter, I'd suggest you carefully examine the trailer wiring, looking for the short that caused the converter...

  • Getting Trailer Running Lights to Work on a 2005 BMW X5 Trailer Wiring Harness
  • Getting the running lights to work would require attaching the correct wire on the trailer wiring harness you are using to the correct wire on the 2005 BMW X5. It will be very similar to the video I have linked showing a typical installation of wiring harness # 119250KIT. You will need to either use the included circuit tester with the wiring harness or # PTW2993 if you need one. Then test the taillight wiring to find the correct wire for the running light circuit. If you do have power...

  • Furrion Cameras Not Working Properly From Running Light Circuit
  • It sounds like the running light pin is not providing enough power for the three cameras. You might need to introduce the 7-Way Vehicle Power Adapter w/ Power Switch for Furrion RV Observation Camera, part # FR87PR, into your electrical system. It is designed to connect the trailer wiring from your tow vehicle's 7-way trailer connector. It will provide your cameras extra power. This should eliminate the intermittent power issues you are having with your camera. I have included product...

  • Troubleshooting a P3 Brake Controller that Will Not go to Sleep
  • The Prodigy P3 Brake Controller # 90195 that you referenced is designed to go to sleep after 15 minutes of no activity. You should note that even opening the door to your vehicle will wake it back up. I would recommend letting it sit for about 20 minutes and then looking through the window to see if the controller has gone to sleep. Be sure not to bump the vehicle either.

  • Solution for Nutsert of Draw Tite Hitch for 2005 BMW X5 that Allows Bolt to Just Spin
  • You are going to have to find a way to hold the nutsert so that you can remove the bolt and try again. It's a pretty tricky situation getting that bolt setup right but you have to do it just like the install instructions and video show. If you push hard enough on the hitch up into the nutsert you should be able to get the hitch to hold it tight enough to the frame to prevent it from moving so that you could remove the bolt.

  • Trailer Mode Won't Turn On After Stealth Hitch Install On BMW X5 XDrive 40i
  • For your Stealth Hitches Hidden Trailer Hitch Receiver w/ Towing Kit - Custom Fit - 2" # SH25VR there are two options. Stealth hitch offers a remote programming option for the BMW you would need to contact Stealth to get this started. If that isn't feasible, you will need to contact a BMW dealer to get them to program it. BMW does make a controller and wire harness that will give you true trailer mode. Just need the dealer to get it for you and install.

  • Tekonsha Primus IQ Trailer Brake Controller # TK90160 Blowing Fuse on 2015 BMW X5
  • I spoke with my contact at Tekonsha and in order to correct the issue of the circuit being overloaded when installing the Primus IQ Trailer Brake Controller, # TK90160, on your 2015 BMW X5, you will need to install a Pulse Preventer, # 5501. The pulse preventer will need to be wired backwards which will allow power to come from the vehicle but will block power from coming out of the controller and back to the vehicle. Once you have installed the pulse preventer, I recommend taking your...

  • Troubleshooting Trailer Valet Squealing When Moving
  • I spoke with my contact at Trailer Valet and she said that what you described sounds like a lack of lubrication which is causing the sound you are describing. You will want to remove the gear cover and lubricate all the moving parts with an emphasis on the chains and the noise should go away. In the manual, which I attached a link to, there is a section on maintenance that you may find helpful.

  • Troubleshooting Tekonsha Prodigy RF Brake Controller with 2010 BMW X5
  • The Prodigy RF Trailer Brake Controller # TK94FR must detect a brake light switch signal at your X5's 7-way connector in order to generate braking signals (unless you press the manual override). The brake signal should appear on both the left and right stop/turn circuits on the X5's 7-way, the contacts at the 3:00 and 9:00 positions. Please refer to the linked photo. If you have a circuit tester like # PTW2993 apply it to these contacts one at a time while a helper presses the brake pedal....

  • Titan Electric Over Hydraulic Actuator Not Working with Redarc Brake Controller
  • If there is something wrong inside your Titan actuator then it has to be tested and repaired by the manufacturer. But the issue might not be a problem with the actuator itself. We can rule it out with some testing. The first test for the Brakerite EHB is to pull the Breakaway switch cable to see if the unit starts and runs normally. If it does not run, disconnect the breakaway battery leads. Then apply the brakes in the tow vehicle or use the manual override on the in cab control to start...

  • Trailer Brakes Pulse with Turn Signal Using the Prodigy RF Brake Controller on a 2011 BMW X5
  • That is not normal operation for the Prodigy RF brake controller # TK94FR. The likely issue is the sensitive nature of the tow package wiring on the 2011 BMX X5. But what you can use is use adapter # C57003 which will maintain more load on the electrical system so that all of the signals running through the RF have a high enough voltage/amperage for it to work properly. In the mean time I recommend using the manual override on the in-cab controller part of the RF to apply constant voltage...

  • Troubleshooting Wiring Harness on a 2001 BMW X5 Where Brake Lights Wont Work with Running Lights
  • Multiplex wiring like on your 2001 BMW X5 can get pretty confusing. A lot of times there are multiple wires that have multiple functions so it's best to test every wire for each function. I've linked a video of the # 119250KIT wiring harness being installed on a 2013 X5 and you can see where the installer finds two wires each have both the brake and the running lights signals on them. However, the voltage is different one having higher voltage for the brakes and the other a higher voltage...

  • Reverse Electric Lockout Not Working on Trailer and 2010 BMW X5 with OEM Wiring Harness
  • You are correct about the bulb out sensor and the adapter # C35FR. There are load resistors built into the adapter to provide more load so that you do not get that sensor. The solenoid should have enough draw without it but it might help. Since it works as it should when connecting the trailer to another vehicle that does sound like and issue on the vehicle side or with the adapter. Be sure to check that the output pin on the adapter matches the one on the trailer that leads to the solenoid...
