Setup and operation of the brake controller you are asking about. Especially note P.6 where it says:
"SETUP
• Preliminary Adjustments
• With the trailer connected press and hold the brake pedal, the Display will
show the Output setting.
• Adjust to 2.0 by turning the control up or down as needed.
• While still holding the brake pedal move the Sync Control slightly, the Display
will change to the Sync setting.
• Adjust to 4o by sliding the Sync Control ahead or back as necessary.
TEST DRIVE
• In an open area, such as a large parking lot, drive forward and apply the
trailer brakes using the Manual Control.
• If the trailer brakes are weak adjust the Output Control up.
• If the trailer brakes jerk or lockup adjust the Output Control down.
• Repeat this step until firm braking is felt without jerking or lockup.
• Once the Output is set, drive forward and press the brake pedal, the tow
vehicle and
• trailer should make a smooth stop.
• If the stop seems slow and more aggressive braking is desired, move the Sync
Control rearward while holding the brake pedal.
• If the stop seems too aggressive adjust the Sync Control rearward while holding
the brake pedal.
• If the stop seems too aggressive adjust the Sync Control rearward while holding
the brake pedal.
• After making a Sync adjustment the Display will show the setting until the
brake pedal is released.
• Make several stops at various speeds and adjust the Sync until stops are smooth
and firm. Slight adjustment of the Output Control may also be desirable.
NOTE: If any problems occur during Setup refer to the Trouble Shooting section
of these instructions."Hope this helps you out. :)
