Sensitivity Level
The sensitivity level adjusts trailer aggressiveness when activated during braking, not manual override. Sensitivity adjustment has no effect on the manual brake
control. The sensitivity can be adjusted for individual driver preference, trailer load changes, or changing road conditions.
TEST DRIVE & ADJUSTMENT
Both the output and sensitivity can be adjusted to achieve smooth, firm stops. Output and sensitivity adjustments should only be made while stopped, with the
transmission in park or neutral, parking brake applied, foot off the brake pedal, and no manual control actuation. Note: Perform the adjustments in a safe environment
with minimal vehicle traffic.
Starting with the output adjustment, drive forward on a dry and level paved or concrete surface. At approximately 25 mph, apply the vehicle’s brakes. If trailer braking
is insufficient, increase the max output setting in the brake control application. If the trailer brakes lock up, decrease the max output. Repeat this process until stops
are firm, just short of lock-up.
Once the output is set, adjust the sensitivity by driving forward at approximately 25 mph and press the brake pedal. The vehicle and trailer should make a smooth
stop. If the stop seems slow and more aggressive braking is desired, increase the sensitivity level through the brake control application. If the stop seems too
aggressive, decrease the sensitivity level in the application.
Make several stops at various speeds and adjust the sensitivity unit stops to be smooth and firm. Slight adjustment to the output control may also be desirable. Note: If
any problems occur during the setup, refer to the ‘Troubleshooting Guide’ on the last page of this manual.
