2019 DODGE DURANGO brake light

NOTE:This module has been designed and verified with
electric trailer brakes and new electric over hydraulic
systems. Some previous EOH systems may not be compat-
ible with ITBM. 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 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, 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 Indi-
cator 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.

2 — GAIN Adjustment Button
3 — Manual Brake Control Lever 354 STARTING AND OPERATING

Repeat steps 8 and 9 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.
Display Messages
The trailer brake control interacts with the instrument
cluster display. 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 “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further information.
WARNING!
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.
CAUTION!
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.
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 aftermar-
ket module is to be installed.
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
356 STARTING AND OPERATING

CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop on level ground, with the engine running.
2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL.
4. Using a ballpoint pen or similar object, push and hold the recessed transfer case NEUTRAL (N) button (located
by the selector switch) for four seconds. The light
behind the N symbol will blink, indicating shift in
progress. The light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is complete. A “FOUR
WHEEL DRIVE SYSTEM IN NEUTRAL” message will
appear in the instrument cluster. 5. After the shift is completed and the NEUTRAL (N) light
stays on, release the NEUTRAL (N) button.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that there is no vehicle movement.
8. Press and hold the brake pedal. Shift the transmission back into NEUTRAL.
9. Firmly apply the parking brake.

STARTING AND OPERATING 363

10. With the transmission and transfer case in NEUTRAL,push and hold the ENGINE START/STOP button until
the engine turns off.
11. Place the transmission gear selector in PARK. Release the brake pedal.
12. Push the ENGINE STOP/START button twice (without pressing the brake pedal) to turn the ignition to the
OFF mode.
CAUTION!
Damage to the transmission may occur if the transmis-
sion is shifted into PARK with the transfer case in
NEUTRAL (N) and the engine running. With the
transfer case in NEUTRAL (N) ensure that the engine
is OFF before shifting the transmission into PARK.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake. NOTE:
•
Steps 1 through 3 are requirements that must be met
before pushing the NEUTRAL (N) button, and must
continue to be met until the shift has been completed. If
any of these requirements are not met before pushing
the NEUTRAL (N) button or are no longer met during
the shift, the NEUTRAL (N) indicator light will flash
continuously until all requirements are met or until the
NEUTRAL (N) button is released.
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be
operable. If the ignition is not in the ON/RUN mode, the
shift will not take place and no position indicator lights
will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indi-
cates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Bring the vehicle to a complete stop, leaving it con-
nected to the tow vehicle.
2. Firmly apply the parking brake.
364 STARTING AND OPERATING

3. Start the engine.
4. Press and hold the brake pedal.
5. Shift the transmission into NEUTRAL.
6. Using a ballpoint pen or similar object, push and holdthe recessed transfer case NEUTRAL (N) button (located
by the selector switch) for one second. 7. When the NEUTRAL (N) indicator light turns off,
release the NEUTRAL (N) button.
8. After the NEUTRAL (N) button has been released, the transfer case will shift to the position indicated by the
selector switch.
9. Shift the transmission into PARK and turn the engine OFF.
10. Release the brake pedal.
11. Disconnect vehicle from the tow vehicle.
12. Start the engine.
13. Press and hold the brake pedal.
14. Release the parking brake.
15. Shift the transmission into DRIVE, release the brake pedal, and check that the vehicle operates normally.

Standing Water
Avoid driving in standing water deeper than 20 inches
(51 cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 20 inches (51 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to LOW if necessary. Refer
to “All-Wheel Drive Operation” in “Starting And Operat-
ing” for further information. Do not shift to a lower gear
than necessary to maintain forward motion. Over-revving
the engine can spin the wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to LOW. Use first gear
and LOW for very steep hills.
If you stall or begin to lose forward motion while climbing
a steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine, and shift
into REVERSE. Back slowly down the hill, allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion, or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle. Always back carefully straight
down a hill in REVERSE gear. Never back down a hill
in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill; always
drive straight up or down.
