RAM 1500 2019 User Manual page 171

The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the
left to activate power to the trailer's electric
brakes independent of the tow vehicle's
brakes. If the manual brake control lever is
activated while the brake is also applied, the
greater of the two inputs determines the
power sent to the trailer brakes.
The trailer and the vehicle's stop lamps will
come on when braking normally with the
vehicle brake pedal. Only the trailer stop
lamps will come on when the manual brake
control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical
connection status.
If no electrical connection is detected after
the ignition is turned on, pushing the GAIN
adjustment button or sliding the manual
brake control lever will display the GAIN
setting for 10 seconds and the "Trailer Brake
Status Indicator Light" will not be displayed.
If a fault is detected in the trailer wiring or
the Integrated Trailer Brake Module (ITBM),
the "Trailer Brake Status Indicator Light"
will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake
control power output to the trailer brakes in
0.5 increments. The GAIN setting can be
increased to a maximum of 10 or decreased
to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer
brake control for the specific towing condi-
tion and should be changed as towing condi-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi-
tions and weather.
Adjusting GAIN
NOTE:
This should only be performed in a traffic
free environment at speeds of approximately

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

trical connections according to the trailer
manufacturer's instructions.
3. When a trailer with electric/EOH brakes
is plugged in, the trailer connected
message should appear in the instrument
cluster display (if the connection is not
recognized by the ITBM, braking func-
tions will not be available), the GAIN
setting will illuminate and the correct
type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the
steering wheel until "TRAILER TOW"
appears on the screen.

trailer on a dry, level surface at a speed
of 20–25 mph (30–40 km/h)
squeeze the manual brake control lever
completely.
