The trailer brake controller assists insmooth and effective trailer braking basedon the towing vehicle’s brake pressure.
INTEGRATED TRAILER BRAKE
CONTROLLER PRECAUTIONS
WARNING: Use the integratedtrailer brake controller to properly adjustthe trailer brakes and check allconnections before towing a trailer.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such asapplication during trailer sway, couldcause instability of trailer or towvehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control ofthe trailer wheels. Trailer wheels canlock up on slippery surfaces, resultingin reduced stability of trailer and towvehicle.
•The trailer brake controller is only afactory-installed or dealer-installeditem. Ford is not responsible forwarranty or performance of thecontroller due to misuse or customerinstallation.
Note:Do not attempt removal of the trailerbrake controller without consulting theWorkshop Manual. Damage to the unit mayresult.
Note:Make sure to set the integrated trailerbrake controller gain to 0 if you are using anaftermarket trailer brake controller.
USING THE INTEGRATED
TRAILER BRAKE CONTROLLER
1.Make sure the trailer brakes are in goodworking condition, functioning normallyand properly adjusted. See your trailerdealer if necessary.
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred. Yourvehicle warranty does not cover issues withyour trailer.
2.Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
Note:Select default mode if the trailer hassurge brakes, or no brakes at all. The systemhas no effect on the braking performanceof the trailer in either of these cases.
Note:If a trailer is connected by a four-pinconnector, the trailer braking function willnot be supported.
3.When you plug in a trailer with electricor electric-over-hydraulic brakes, amessage confirming connectionappears in the information display.
4.Use the gain adjustment to find thedesired starting point. A gain setting of6.0 is a good starting point for heavierloads.
Note:Use the following steps to adjust thegain setting whenever road, weather andtrailer, or vehicle loading conditions, changefrom when you initially set the gain.
5.In a traffic-free environment, tow thetrailer on a dry, level surface andsqueeze the manual control levercompletely.

6.If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
Note:Only perform this procedure atspeeds of approximately 20–25 mph(30–40 km/h).
Note:The trailer brake controller reducesoutput at vehicle speeds below 11 mph(18 km/h) so that trailer and vehicle brakingis not jerky or harsh. This feature is onlyavailable when applying the brakes usingyour vehicle's brake pedal, not thecontroller.
Note:Your vehicle's brake system and thetrailer brake system work independently ofeach other. Changing the gain setting on thecontroller does not affect the operation ofyour vehicle's brakes whether you attach atrailer or not.
Note:With the proper electrical connection,pressing your vehicle brake pedal or usingthe manual control lever illuminates bothtrailer and vehicle brake lamps.
Note:When you switch the engine off, thecontroller output is disabled and the displayand module shut down. The controllermodule and display turn on when you switchthe ignition on.
Note:Trailer braking is suspended duringstop/start events to minimize battery draw.
Adjusting the Trailer Brake Gain
Use the gain adjustment (+) and(-) buttons to increase ordecrease the gain setting to thedesired starting point. The trailerbrake controller allowsadjustment of brake gain from0% to 100% in 5% increments.
A
