Trailer Gain Adjustment Procedure Trailer Gain should be set for a specific trailering condition and must be adjusted any time vehicle loading, trailer loading, or road surface conditions change. Setting the Trailer Gain properly is needed for the best trailer stopping performance. A trailer that is over-gained may result in locked trailer brakes. A trailer that is under-gained may result in not enough trailer braking. Both of these conditions may result in poorer stopping and stability of the vehicle and trailer. In the Trailer Output display on the DIC will disappear if there is no error present. Connecting a trailer without electric brakes will not clear the six dashed lines. 4. Adjust the Trailer Gain by using the gain adjustment (+ / -) buttons on the Trailer Brake Control Panel. 5.

Adjusting trailer gain at speeds lower than 32 to 40 km/h (20 to 25 mph) may result in an incorrect gain setting. A TRAILER CONNECTED message will be briefly displayed on the DIC. The Trailer Brake Display Page will appear on the DIC showing TRAILER GAIN and TRAILER OUTPUT. .
