Normal Operation

WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster continually communicates with the trailer brake control (TBC) module along the high speed controller area network (HS-CAN). If the instrument cluster is configured for trailer brakes and the TBC module is not installed, the cluster will display this message.
