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.
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.
