StabiliTrak systems to activate,
power sent to the trailer's brakes
will be automatically adjusted to
minimize trailer wheel lock-up.
This does not imply that the trailer
has StabiliTrak.
2500 and 3500 series vehicles with
StabiliTrak have a Trailer Sway
Control (TSC) feature. See Trailer
Sway Control (TSC) on page 9‑123.
2500 and 3500 series vehicles
with StabiliTrak have a Hill Start
Assist (HSA) feature. See Hill Start
Assist (HSA) on page 9‑70.
If the vehicle’s brake, antilock
brake, or StabiliTrak systems are
not functioning properly, the ITBC
system may not be fully functional
or may not function at all. Make
sure all of these systems are
fully operational to ensure full
functionality of the ITBC system.
The ITBC system is powered
through the vehicle's electrical
system. Turning the ignition off
will also turn off the ITBC system.
The ITBC system is fully functional
only when the ignition is in ON or
in RUN.
The ITBC system can only be used
with trailers with electric brakes.

WARNING
Connecting a trailer that is not
compatible with the ITBC system
may result in reduced or complete
loss of trailer braking. There may
be an increase in stopping
distance or trailer instability which
could result in personal injury or
damage to the vehicle, trailer,
or other property. An aftermarket
controller may be available for
use with trailers with surge, air,
or electric‐over‐hydraulic trailer
brake systems. To determine the
type of brakes on the trailer and
the availability of controllers,
check with your trailer
manufacturer or dealer.
When trailering, make sure of the
following:
.
The ITBC system is used only
with trailers that are equipped
with electric brakes.
.
All applicable local and federal
laws and regulations are
followed.
.
All electrical and mechanical
connections to the trailer are
made correctly.
.
The trailer’s brakes are in proper
working condition.
.
The trailer and vehicle are
properly loaded for the towing
condition.
The ITBC system is a
factory-installed item. Out‐of‐factory
installation of this system should not
be attempted. GM is not responsible
for warranty or performance of the
system resulting from out‐of‐factory
installation.
