After a few hours of being inactive (with a trailer connected), the display will go blank.
While the display is blank, very little power will be used by the Genesis.

Minimum Power

:  (for Manual and Automatic operation) 

CAUTION:

 

In the automatic mode and minimum power setting of 5 or 10, the trailer
brakes are applied only when the sensor detects deceleration.

With the vehicle at rest and the brake pedal depressed, there should be no or
slight output to the trailer brakes (when minimum power is set to 5 or 10).

Higher at rest outputs and reverse braking can be obtained by increasing the
minimum power setting.

!

The controller is factory pre-set to 10%.  At this setting, the MINIMUM amount of power that will be 
immediately applied to the trailer brakes is 10% (when the brake pedal is depressed and before 
deceleration is detected). 

Changing Minimum Power (Manual and Automatic) 

Changing the minimum power level is designed to allow more or less power to be delivered to the 
brakes when the controller does not sense deceleration.  See the section for loaded trailer weight 
guidelines on the last page of this document.  Select the minimum power setting required for your 
loaded trailer weight. 

The minimum power level may be changed in 5% increments (5, 10, 15, 20, and 25) 

To do this, follow these steps: 

With the vehicle at rest

1.

, press the “-” button until the display flashes then release the button.

The display will flash a number, which corresponds to the set minimum power as a percentage
of total available power (5, 10, 15, 20, and 25).

2. To change the set value, press the “-” button and release.  The display will change to the next

highest available value with sequential presses of the “-” button.

3. Continue pressing the “-” button until the desired minimum power level is displayed on the

display.

4. Press the “+“ button until display stops flashing and release.
5. The new minimum power level is now set.

NOTE: The higher the minimum power setting the more aggressive the braking. A setting
of 5 will delay the braking output a small amount.
