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 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. This message clears if the
trailer is reconnected. This message also clears if you
acknowledge it. If this message still displays, either your
vehicle or the trailer needs service. See your dealer.
