Try unplugging the brake controller for 10 seconds or so and then replugging it in. Sometimes brake controllers like the part # C24VV just need to be reset and this is the corret way to do that.

After 8 months of using the C51140 with no issues the controller now flashes either L5 or the output I set at 8.5. This happens even after the truck has been off overnight, or just while driving straight even without hitting the brakes or making any adjustments. After testing all wiring connections the issue is still present. Does the unit have a warranty?

First thing to check is to see if your truck's third brake light is still working when you hit the brakes. When the fuse for that circuit goes on GM trucks like your 2014 model it will prevent the brake controller from activating when the brakes…

Hey Mark, What gauge wire did you use to run from the junction box to the brake assemblies? If you didn't use at least 10AWG wire #10-1-1 that could explain the heat build up and voltage drop. I don't recommend leaving the manual override…

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…

It sounds like you're getting an output of 0.5 on auto. The manual setting on your #C24VV won't have an impact on the output aside from when you use the manual control. Based on what you're describing it sounds like you need to adjust the…

Hello Dan, I can definitely help with this. It is completely normal for the Curt TriFlex brake Controller #C24VV to show the current gain setting when the brakes are applied, or when the manual override is pressed. It sounds like you have the gain…

Answer 10

It sounds like your brake output circuit may be shorting out to the stoplight circuit of your trailer wiring and that is why the brakes want to lock up immediately. An easy way to test this is to check to see if the brakes end up pulsating when you…

On the backside of your Curt Triflex part #C24VV trace the wiring for about 8 inches and you'll come to a plastic harness that you'll need to unplug. Once you wait a few seconds go ahead and plug it back in.

Something is obviously causing a voltage drop between the brake controller and the trailer connector. The usual culprit in this type of situation is a break in the wire or a corroded wire. Check the wiring under the truck. You should be able to trace…
