CHECK TRAILER WIRING
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
this message may display and a
chime may sound when one of the
following conditions exists:
A trailer with electric brakes
becomes disconnected from the
vehicle.
If the disconnect occurs while
the vehicle is stopped, this
message clears itself after a
short time.
If the disconnect occurs while
the vehicle is moving, this
message stays on until the
ignition is turned off.
There is a short in the wiring to
the electric trailer brakes.
When this message displays, power
is no longer available to the trailer
brakes.
As soon as it is safe to do so,
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. This message clears if the trailer
is reconnected. This message also
clears if you acknowledge it. If this
message still displays, either the
vehicle or the trailer needs service.
