Introduction
Dexter is proud to put control and peace of mind in towing a trailer, horse float or caravan back into your hands with the Dexter Sway Control System. This innovative safety device automatically stabilises the sway of a trailer. It works independently of the tow vehicle and automatically applies the trailer or caravan brakes in the event of a sway. As you are driving, the Dexter Sway Control System is constantly monitoring trailer yaw, or side-to-side movement, quickly recognising and adjusting for sway conditions. This manual is designed to provide information for you to understand, use, and guide you through the process of installing, operating, and maintaining your Dexter Sway Control System

! CAUTION
This is the safety alert symbol. It is used to alert you to potential injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
CAUTION
The Dexter Sway Control should only be installed by a certified DSC technician
DSC Trailer Mounting
DSC Mounting Location
Select a location on the trailer to mount the DSC. The location must be between 1500mm to 3000mm behind the towball and shielded from road debris. The DSC must be securely fastened onto a vertical surface that does not flex or move from wind, such as plastic covers or plastic walls. The center of the DSC (marked by a red dot on the DSC label shown below) must be positioned on the "center line" of the trailer and the DSC must be mounted with the correct side in the UP direction as indicated on the label. The longest edge of the DSC (as indicated by a red line on the label) must be mounted parallel to the trailer axle beam(s). See Figure 1

alko.com.au

3

It is essential that the DSC be oriented in the proper direction when it is installed.
CAUTION
Ensure the electric brakes are adjusted and maintained in accordance with the manufacturer's recommendations in your owner's manual for
proper operation of the sway control module.
Mounting Hardware
The DSC should be mounted using the mounting flanges which are located on both sides of the unit. Included are six (6) self-tapping screws, four (4) 3/16" x 18mm hexagon head screws to mount the DSC to the trailer and two (2) 9/64" x 18mm button head screws to mount the Status Light Module. You must securely tighten the mounting screws to hold the DSC firmly in position and to avoid becoming loose from vibration.
You must NOT drill holes in the DSC for any reason. Drilling holes or puncturing the unit VOIDS YOUR WARRANTY.
CAUTION
Do not spray high pressure water on the DSC. The DSC is a weather sealed water resistant unit, but it is not designed to withstand direct
high pressure spray from a power washer.

The DSC pink wire must be connected to the right side electric brakes with a 14 gauge (min.) wire (or 5mm automotive wire).

The 14 gauge wires of the DSC wiring harness are approximately 300mm long to allow for flexibility when mounting the unit. Extensions will be required to connect unit to the trailer's electrical wiring. When making connections to the trailer's wiring harness, the desired termination is a solder joint. If the connection is not soldered, use the appropriate size and type of "crimp-type" weather sealed heat-shrink connectors, using the manufacturer's recommended crimping tools in accordance with their crimping instructions.

Once the 14 gauge wires are connected, route the Status Light wire to a location on the front of the trailer and mount the Status Light Module onto a flat surface using self-tapping screws. Select a location that makes it easy to see the Status Light when looking at the front of the trailer.
NOTE: For 14 gauge wire, 5mm auto wire is suitable.

Dexter Sway Control Wiring - Power from Trailer Battery

Taking shortcuts when connecting any wires on your trailer only increases the likelihood that some part of your electrical system will fail. Make sure your soldered connections are durable and sealed against exposure to water and corrosive elements. One loose wire connection can disable your entire trailer brake system.
When adding extension wires to the DSC wiring harness, you must use the correct gauge wire. These gauge sizes are outlined in the table.
! CAUTION
Failure to use the correct gauge wire may result in poor braking performance or brake failure. Improper wire gauge may also result in significant damage to your trailer or its components, cause a fire, which may result in serious or fatal injury and/or property damage. Undersized wire will prevent electrical circuit protection devices such as fuses or circuit breakers from functioning properly. Undersized wire may melt or
burn before these safety devices can be activated.
Final Wiring Check
1.LEFT SIDE / CURB SIDE
Refer to Figure 1 on page 5 to verify correct wiring on the left side of the trailer. Ensure that ONLY the PURPLE and WHITE wires are connected to the left side trailer brakes wired in parallel and not in series.
2.RIGHT SIDE / DRIVER SIDE
Refer to Figure 7 on page 11 to verify correct wiring on the left side of the trailer. Ensure that ONLY the PINK and WHITE wires are connected to the left side trailer brakes wired in parallel and not in series.
CAUTION
It is very important that the trailer brake controller wire from the tow vehicle (blue wire) is ONLY connected to the BLUE wire on the DSC and
NOT connected directly to the trailer brakes.

Status Light and T

3.STARTUP
After performing the final brake wiring check, the DSC is ready for start-up. The operational status of the DSC is indicated by the LED status light. The DSC is in SLEEP MODE if the LED light is off (dark). The DSC will start-up (wake-up) when voltage is applied to the BLUE WIRE. Once the trailer is connected to the tow vehicle, apply the manual override on the trailer brake controller in the truck. The LED status light should begin flickering GREEN if the system is installed correctly. If the LED status light does not come on when applying the manual override on the brake controller, refer to the troubleshooting table on page 25.
The DSC Status Light Module
The DSC performs a self-diagnostic test every time it "wakes up" by receiving a signal from a brake controller in the tow vehicle. The light will flash RED and GREEN approximately six times on startup and then go to GREEN. The DSC also continually monitors system parameters during operation. If the system is operating properly and no faults are detected, the GREEN light will remain ON and flicker or pulse. If a problem is detected, a RED light will flash a specific number of times to indicate the specific problem. The following Status Light and Troubleshooting table contains the meaning of the different RED and GREEN light flashes along with troubleshooting suggestions to correct the problem(s).
The DSC continues checking the fault status and keeps the RED light flashing until the fault is corrected. Once corrected, the GREEN light returns. Note that when the trailer is not moving, every 60 seconds the GREEN light will turn off for three seconds and back on. This is normal and indicates proper operation of the DSC. If the GREEN light is not turning off and on every 60 seconds while the trailer is not moving, have the DSC checked by your local service center.

How the Dexter Sway Control Works

How the Dexter Sway Control Works

1. The DSC continuously monitors trailer yaw (side-to-side movement).

2. It has a proprietary algorithm which is used to determine the difference between quick steering to avoid a road obstacle (or other such circumstances) and the rapid onset of a trailer swaying event.

Blue

Brake controller blue wire.

Pink

Purple

3. It measures the angle, travel distance and speed of the lateral motion of the trailer (and other parameters) and uses this information to quickly intervene with the application of trailer brakes.

4. The processing capability of the DSC is powerful and rapid. It captures all the critical elements of the swaying condition and uses this information to predict how the event will proceed without any driver intervention.

The Dexter Sway Control applies the trailer
brakes in a manner to dampen and control a trailer swaying event.

4. The processing capability of the DSC is powerful and rapid. It captures all the critical elements of the swaying condition and uses this information to predict how the event will proceed without any driver intervention.

Important
Ensure the electric brakes are adjusted and maintained in accordance with the
manufacturer's recommendations in your owner's manual for proper
operation of the sway control module.

5. It uses this data to get ahead of the event by applying the brakes on the correct side of the trailer, in a timely manner, with the proper braking level for the required duration.

6. This quickly damps and brings the trailer sway under control.

7. The DSC is based on a similar technology principle that is used in automotive vehicle stability systems.
