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.

See your dealer.

See Integrated Trailer Brake Control System under Towing Equipment on page 9‑100 for more information.

ICE POSSIBLE DRIVE WITH CARE

This message displays when ice conditions are possible.

TRAILER CONNECTED

On vehicles with the Integrated Trailer Brake Control (ITBC) system, this message displays briefly when a trailer with electric brakes is first connected to the vehicle.

This message clears itself after several seconds. This message also clears if you acknowledge it. After this message clears, the TRAILER GAIN/OUTPUT display appears in the DIC.

See TRAILER GAIN/OUTPUT under Driver Information Center (DIC) on page 5‑33 and Integrated Trailer Brake Control System under Towing Equipment on page 9‑100 for more information.
