- Troubleshooting Curt TriFlex Brake Controller Not Showing Activation
- On your Curt TriFlex Trailer Brake Controller # C24VV, the decimal point as you put it is standby mode with no trailer connected. The blank screen is also standby mode and that screen is what is seen when simply starting the vehicle, but that screen should illuminate when you press the manual override or show the decimal point when you hit the brake pedal only while moving since it is a proportional controller. If it does not operate under those criteria, then you will need to have the...

- The fact that the brake lights on your trailer are staying on all the time indicates a possible short somewhere in the vehicle or trailer wiring. Although it's pretty unlikely with the connector being new, I recommend first checking the connector at the rear of the vehicle for any dirt or debris that might be causing a short.
If the connector looks fine, I recommend moving to the vehicle wiring harness.

- It looks like you purchased and installed the LED Trailer Tail Light w/ Reflector - Stop, Tail, Turn - Submersible - 7 Diodes - Round - Red Lens # STL13RFHXB on a trailer. Typically when this happens it indicates a bad ground somewhere on the trailer, so you'll want to check the ground connection on the right side light, as well as any ground wire for the entire trailer.
This would be a great starting point for your troubleshooting, but if all of your ground wires are firmly connected...

- We need to determine if the issue is on the vehicle side or the trailer side, so first disconnect the trailer and then use a circuit tester like # PTW2992 or the one that came with your ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT. If the functions don't work correctly for each pin like in the video then you will want to go back to your sensor connections and retest them. You also want to make sure the ground ring terminal is connected bare metal to metal and some sand paper...

- The brakes on your new RV trailer can be activated either by the brake controller or the trailer's own on-board emergency breakaway system. I have not heard of an issue with the Echo # C51180 before now, and while it is possible the unit has an internal malfunction I suspect the problem is more likely to be in either the trailer's breakaway system or within the 7-way wiring on the Audi or the trailer.
For the trailer brakes to lock up without you pressing the brake pedal they would need...

- I can not recommend you do that since that battery is going to drain pretty quickly and leave you without trailer lighting and you'll have no way of knowing while driving. I know it seems like a hassle but running the power wire up to the vehicle battery is the only safe way we can recommend you install the part # 119250KIT in your 2017 Audi A3.

- Your 2013 Audi A6 has trailer wiring circuits that are combined what use pulse width modulation on the same wire.
So according to Tekonsha when you install the # 119250KIT you need to attach the yellow wire of the kit to the brake/tail/left turn wire on the vehicle and the green to the brake/tail/right turn wire. The brown and red wires of the kit are not used.

view full answer... - My Curt Echo Will Not Power On Without Being Connected To My Camper on 2020 Audi Q7
- Your 2020 Audi Q7 has a trailer mode and will only send power through the 7-way charge line when it senses a trailer that requires 12v power is connected. This is why the Curt Echo # C51180 will only start to receive power on your camper when the 7-way is plugged in.
If your boat trailer uses an electric brake system there should be a breakaway battery that is tied to the 7-way charge line that will ensure the battery is kept charged. If you do not have a breakaway battery and do have...
view full answer... - Troubleshooting ZCI Circuit Protected Wiring Harness for 2013 Audi Q7
- I would start by double checking your 4-way connection. Make sure it is clean and that there is no dirt or debris that could be causing an issue.
If everything looks good, consider moving the ground. I realize you already checked to make sure it was on bare metal, but this is typically the problem when using one turn signal engages turn signals on both sides of the trailer. You may also need to run a new ground wire if there is a short.
In order to test the sensors there are a few things...

- I spoke with my contact at Reese and he said they have not had any reported issues that the rivet nuts included with the Dual Cam sway control were too small. Just to be sure, you can check the knurls of the nut with a dial caliper to make sure they are slightly larger than 11/16 of an inch, or 0.6875 inches if you use a digital caliper.
Your solution is the exact same solution that Reese recommends in this situation. Drill completely through the frame and run bolts to the opposite side....

- Your 2021 Audi Q7 is going to have a smart wiring system. For the Curt Echo # C51180 to function properly and receive power you will need to connect your trailer 7-way to the Echo once you plug into the connector on your Audi. The computer in your Audi wants to see a full trailer connection before it will send power to the 12 volt circuit that powers the Echo. Your Audi will also have a trailer tow mode that should also be selected while you are towing.

- My concern is the Curt TriFlex Trailer Brake Controller # C24VV not getting enough power on your 2018 Audi Q7. There is a technical bulletin which I have linked below since the wiring on your Q7 will not provide enough power to the trailer brakes which is causing the OL error you are getting. You will need the following components from your Audi dealer.
1 connector housing (#1J0-972-782)
2 wire/terminal assemblies (#000-979-228)
These will help you to wire in a 30-Amp Relay # BL63VR....

- It sounds like you have checked everything following your # C59236. A single harness failure happens sometimes but two in a row is not something we really see. The only thing I can think of is checking the power source. Make sure you are in fact hooked up to the vehicle battery.
Outside of that, I can only recommend using the Tekonsha Upgraded Heavy Duty ModuLite Circuit Protected Vehicle Wiring Harness # 119250KIT instead. Tekonsha is the most reliable when it comes to wiring so if it...

- The issue you are having is actually not that uncommon on German vehicles like your 2020 Audi Q8 as you have read.
The adapter like the # C73NR, or using a domestic vehicle with a functioning 7-way connector can be required to pair the Tekonsha Prodigy RF Wireless Trailer Brake Controller # TK94FR on some German vehicles.
The reason the adapter helps is it puts extra load on the system and is more likely to allow the Prodigy RF # TK94FR to recognize it for pairing.
Either using # C73NR...
