TRAILER CONNECTED:

Displays when the system

senses a correct trailer wiring

connection during a given

ignition cycle.

TRAILER DISCONNECTED:
Displays, accompanied by a
single audible time, when the
system senses a trailer
connection and then a
disconnection, either
intentional or unintentional,
during a given ignition cycle. It
also displays if a truck or
trailer-wiring fault occurs

causing the trailer to appear
disconnected. This message

can also display if you use the

manual control lever without a

trailer connected.

Procedure for Adjusting Gain

Note: Only perform this procedure

in a traffic-free environment at

speeds of approximately 20-25
mph (30-40 km/h).
The gain setting sets the trailer

brake controller for the specific
towing condition. You should

change the setting as towing

conditions change. Changes to

towing conditions include trailer

load, vehicle load, road conditions
and weather.

The gain should be set to provide

the maximum trailer braking

assistance while making sure the

trailer wheels do not lock when

using the brakes. Locked trailer
wheels may lead to trailer
instability.

1. Make sure the trailer brakes are

in good working condition,
functioning normally and
properly adjusted. See your
trailer dealer if necessary.

2. Hook up the trailer and make

the electrical connections
according to the trailer

manufacturer's instructions.

3. When you plug in a trailer with

electric or

electric-over-hydraulic brakes,

TRAILER CONNECTED

appears in the information
display.

4. Use the gain adjustment (+ and

-) buttons to increase or

decrease the gain setting to the

desired starting point. A gain

setting of 6.0 is a good starting
point for heavier loads.

5. In a traffic-free environment,

tow the trailer on a dry, level

surface at a speed of 20-25

mph (30-40 km/h) and

squeeze the manual control

lever completely.

6. If the trailer wheels lock up,

indicated by squealing tires,
reduce the gain setting. If the
trailer wheels turn freely,
increase the gain setting.
Repeat Steps 5 and 6 until the
