brakes Ram 5500 Chassis Cab 2012 User Guide

The trailer and the vehicle’s brake lamps will come on
when either vehicle braking or manual trailer brakes are
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, pressing 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 (+/-)
Pressing these buttons will adjust the brake control
power output to the trailer brakes in 0.5 increments. TheGAIN 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 condition and should be changed
as towing conditions change. Changes to towing condi-
tions include trailer load, vehicle load, road conditions
and weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic free
environment at speeds of approximately 20–25 mph
(30–40 km/h).
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 connec-
tions according to the trailer manufacturer’s instructions.
360 STARTING AND OPERATING

3. When a trailer with electric brakes is plugged in, the
GAIN setting will illuminate.
4. Use the GAIN adjustment (+/-) buttons to increase or
decrease the GAIN setting to the desired starting point. A
GAIN setting of 6 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 brake control lever completely.
6. If the trailer wheels lockup (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 GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier
trailer, trailer wheel lockup may not be attainable even
with the maximum GAIN setting of 10.EVIC Display Messages
The trailer brake control interacts with the Electronic
Vehicle Information Center (EVIC). Display messages,
along with a single chime, will be displayed when a
malfunction is determined in the trailer connection,
trailer brake control, or on the trailer. Refer to “Electronic
Vehicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
CAUTION!
The ITBM module has been designed and verified
for electric trailer brakes. Connecting a trailer that is
not compatible with the ITBM system may result in
reduced or complete loss of trailer braking. There
may be a increase in stopping distance or trailer
instability which could result in damage to your
vehicle, trailer, or other property.

STARTING AND OPERATING 361

WARNING!
The ITBM module has been designed and verified
for electric trailer brakes. Connecting a trailer that is
not compatible with the ITBM system may result in
reduced or complete loss of trailer braking. There
may be a increase in stopping distance or trailer
instability which could result in personal injury.
NOTE:
•An aftermarket controller may be available for use
with trailers with air or electric-over-hydraulic trailer
brake systems. To determine the type of brakes on
your trailer and the availability of controllers, check
with your trailer manufacturer or dealer.
•Removal of the ITBM will cause errors and it may
cause damage to the electrical system and electronic
modules of the vehicle. See your authorized dealer if
an aftermarket module is to be installed.
Towing Requirements – Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
NOTE:Do not cut or splice wiring into the vehicle’s
wiring harness.
WARNING!
Any work done to the vehicle’s electrical system or
wiring should be performed by a qualified automo-
tive technician. If done improperly it may cause
damage to the electrical system wiring and could
result in serious or fatal injury.
Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
362 STARTING AND OPERATING

WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.
Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service or immediately
if the brake system warning lamp indicates system
failure.The brake master cylinder has a translucent plastic
reservoir. On the outboard side of the reservoir, there is a
“MAX” dot and an “MIN” dot. The fluid level must be
kept within these two dots. Do not add fluid above the
MAX mark because leakage may occur at the cap.
With disc brakes the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Use only the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
