Trailer Sway Control (Tsc) - Cadillac Escalade 2022 Owner's Manual

352 DRIVING AND OPERATING
CHECK TRAILER WIRING: This
message will display if:
The ITBC system first determines
connection to a trailer with electric
brakes and then the trailer harness
becomes disconnected the vehicle.
If the disconnect occurs while the
vehicle is stationary, this message
will automatically turn off in about
30 seconds. This message will also
turn off if it is acknowledged or if
the trailer harness is reconnected.
If the disconnect occurs while the
vehicle is moving, this message will
continue until the ignition is turned
off. This message will also turn off if
it is acknowledged or if the trailer
harness is reconnected.
There is an electrical fault in the
wiring to the trailer brakes. This
message will continue as long as
there is an electrical fault in the
trailer wiring. This message will also
turn off if it is acknowledged.
To determine whether the electrical
fault is on the vehicle side or trailer
side of the trailer wiring harness
connection:
1. Disconnect the trailer wiring
harness from the vehicle.
2. Turn the ignition off.
3. Wait 10 seconds, then turn the
ignition back to RUN.
4. If the CHECK TRAILER WIRING
message reappears, the electrical
fault is on the vehicle side.
If the CHECK TRAILER WIRING
message only reappears when
connecting the trailer wiring
harness to the vehicle, the
electrical fault is on the trailer side.
SERVICE TRAILER BRAKE SYSTEM:
This message will display when there
is a problem with the ITBC system.
If this message continues over
multiple ignition cycles, there is a
problem with the ITBC system. Have
the vehicle serviced.
If either the CHECK TRAILER WIRING
or SERVICE TRAILER BRAKE SYSTEM
message displays while driving, the
ITBC system may not be fully
functional or may not function at all.
When traffic conditions allow,
carefully pull the 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 either of these messages
continues, either the vehicle or trailer
needs service.
A GM dealer may be able to diagnose
and repair problems with the trailer.
However, any diagnosis and repair of
the trailer is not covered under the
vehicle warranty. Contact your trailer
dealer for assistance with trailer
repairs and trailer warranty
information.

Trailer Sway Control (TSC)

Vehicles with StabiliTrak/Electronic
Stability Control (ESC) have a Trailer
Sway Control (TSC) feature. Trailer
sway is unintended side-to-side
motion of a trailer while towing. If the
vehicle is towing a trailer and the TSC
detects that sway is increasing, the
vehicle brakes are selectively applied
at each wheel, to help reduce
excessive trailer sway. If equipped with
the Integrated Trailer Brake Control
(ITBC) system, and the trailer has an
electric brake system, StabiliTrak may
also apply the trailer brakes.
