SERVICE TRAILER BRAKE SYSTEM
On vehicles with the Integrated Trailer Brake
Control (ITBC) system, this message displays and
a chime sounds when there is a problem with
the ITBC system.
When this message displays, power is no longer
available to the trailer brakes.
As soon as it is safe to do so, carefully pull your
vehicle over to the side of the road and turn
the ignition off. Check the wiring connection to the
trailer and turn the ignition back on. If this
message still displays, either your vehicle or the
trailer needs service. See your dealer.
See “Integrated Trailer Brake Control System”
under Towing a Trailer on page 449 for more
information.
STABILITRAK OFF
If your vehicle has StabiliTrak
®
, this message
displays when you turn off StabiliTrak
®
, or when
the stability control has been automatically
disabled. To limit wheel spin and realize the full
benefits of the stability enhancement system, you
should normally leave StabiliTrak
®
on. However,
you should turn StabiliTrak
®
off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. See If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 426. To
turn the StabiliTrak
®
system on or off, see
StabiliTrak
®
System on page 385.
There are several conditions that can cause this
message to appear.
•
One condition is overheating, which could
occur if StabiliTrak
®
activates continuously
for an extended period of time.
•
The message also displays if the brake
system warning light is on. See Brake System
Warning Light on page 262.
•
The message could display if the stability
system takes longer than usual to complete its
diagnostic checks due to driving conditions.
•
The message displays if an engine or vehicle
related problem has been detected and the
vehicle needs service. See your dealer.
•
The message also displays if the vehicle is
shifted into 4LO.
The message turns off as soon as the conditions
that caused the message to be displayed are
no longer present.
