The gain setting sets the trailer brakecontroller for the specific towing condition.You should change the setting as towingconditions change. Changes to towingconditions include trailer load, vehicle load,road conditions and weather.
The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailer wheelsmay lead to trailer instability.
1.Make sure the trailer brakes are in goodworking condition, functioning normallyand properly adjusted. See your trailerdealer if necessary.
2. Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
3.When you plug in a trailer with electric orelectric-over-hydraulic brakes, a messageconfirming connection appears in theinformation display.
4.Use the gain adjustment (+ and -) buttonsto increase or decrease the gain settingto the desired starting point. A gainsetting of 6.0 is a good starting point forheavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20–25 mph (32–40 km/h) andsqueeze the manual control levercompletely.
6.If the trailer wheels lock up, indicated bysquealing tires, reduce the gain setting.If the trailer wheels turn freely, increasethe gain setting. Repeat Steps 5 and 6until the gain setting is at a point justbelow trailer wheel lock-up. If towing aheavier trailer, trailer wheel lock-up maynot be attainable even with the maximumgain setting of 10.
Explanation of Information Display WarningMessages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your warranty does not cover thisdiagnosis if the fault is with the trailer.
A message indicating a trailer brake modulefault may display in response to faults sensedby the trailer brake controller, accompaniedby a single tone. If this message appears,contact an authorized dealer as soon aspossible for diagnosis and repair. Thecontroller may still function, but performancemay be degraded.
A message indicating a trailer wiring faultmay display when there is a short circuit onthe electric brake output wire. If this messagedisplays, accompanied by a single tone, withno trailer connected, the problem is with yourvehicle wiring between the trailer brakecontroller and the 7-pin connector at thebumper. If the message only displays with atrailer connected, the problem is with thetrailer wiring. Consult your trailer dealer forassistance. This can be a short to ground(such as a chaffed wire), short to voltage(such as a pulled pin on trailer emergencybreakaway battery) or the trailer brakes maybe drawing too much current.
