CURT Trailer Brake Control

Welcome to the curt triflex explanation user’s guide in this explanation we’re going to cover

controls and components installation and mounting calibration and adjustment and

go over a few quick tips the digital display will show you output settings

sensitivity settings trailer connection calibration and troubleshooting errors

the sensitivity adjustment control allows you to adjust the aggressiveness

of the trailers breaking during calibration the output adjustment wheel

allows you to adjust the amount of power that you send to your trailer brakes

during normal operation the manual control ever acts as a handbrake for

your trailer this can be set up to output the amount of power that you

previously configured with the adjustment wheel or 100{7d2fe645517a6f04b15231d3dc07553115931ab4bab7ca947bc4445e09b369cd} power to toggle

between a hundred percent output and the amount of output that you previously set

with the adjustment wheel there’s a switch on the back of the controller on

the right hand side here the factory default setting is on and will output

the amount of power that you previously set with the adjustment wheel flip the

switch up to allow for 100{7d2fe645517a6f04b15231d3dc07553115931ab4bab7ca947bc4445e09b369cd} output the switch on the left allows you to toggle

brake light activation when the manual control lever is depressed the factory

default setting is on and will emit power to your trailer brake lights

flip the switch up to the off position if you don’t want your trailer brake

lights to activate when the manual control lever is used when it comes to

mounting your control there are a few guidelines you must follow make sure

that you’re attaching it to a solid surface and then that area is easily

reached by the driver also make sure the area behind the mounting location is

clear so no damage is done while drilling the control can be mounted 20

degrees in any direction the only variance is pitch we mounted 20

degrees down or 70 degrees up choose what setup is best for you and your

vehicle once you’ve chosen your mounting location use the bracket as a template

to mark and drill the eighth inch holes needed to secure the bracket once again

make sure that the area that you’re drilling into is clear so you’re not

damaging any of your vehicle’s components or features depending on the

moaning location you may want to attach the control the bracket using the four mounting

screws before attaching it to the dash there might not be enough room to access

the mounting screws once the bracket is attached to the dash use a screwdriver a

quarter inch nut driver to secure the bracket with the provided self tapping

screws be careful not to over tighten them each vehicle is different when it

comes to connecting the tri flex to your vehicle you will need a curt wiring

harness with quick plug like we have here in this dot some vehicles are not

equipped with a factory brake control plug and will require you to hardwire it

in now that the tri flex is connected we see a single decimal point on the

display we can move on to setting up the control for towing if your triflex

display is blank don’t be alarmed after a short period of time of no activation

the trifecta goes into power conservation or sleep mode this

essential feature was added to eliminate potential battery drain once the vehicle

is off before we connect the electrical components of the trailer to the truck

we need to make sure that we’re parked on a level surface if the triflex is not

calibrated on a level surface the trailer will not break properly when

traveling down different grades now that we’ve connected the trailer to

the truck we should have a cc appear on the display followed by two decimal

points or our see if RC appears that means recalibration is needed and we

need to disconnect and reconnect the trailer and truck if two decimal points

appear the unit is calibrated and ready for setup before we take a test drive we

need to make some preliminary adjustments start the vehicle to ensure

proper charge make sure that the vehicle is in park and keep your foot off the

brake pedal adjust the output to 2.0 in the sensitivity to l1 these settings will

flash while the adjustments are made and for a few seconds after now we’re ready

for a test-drive it’s best to start with the output adjustment drive forward on a paved

surface that is dry and level at around 25 miles per hour apply the tow vehicle brakes if the

trailer braking is insufficient adjust the output control wheel to the right

if the trailer brakes lock up adjust the output control to the left repeat this

process until the stops are firm just short of lockup once the output is set

we should adjust the sensitivity once again drive for it at 25 miles per hour and

apply the brake the vehicle and trailer should make a smooth stop if the stop

seems slow and more aggressive braking is desired move the sensitivity control

towards the driver and move it away if the braking is too aggressive repeat

this process until you are happy with the results you may need to make some

slight adjustments to the output control if any problems occur during setup use

the troubleshooting guide of your user manual or visit curtain FG comm

light pressure on the manual control will activate the trailer brakes with no

effect to the tow vehicles brakes this is useful for slowing down steep grades

or before stops this is also helpful for controlling trailer sway periodic

adjustments and sensitivity settings may be necessary to correct for changing

road conditions trailer loading or brake wear.
