DESCRIPTION AND OPERATION > TRAILER BRAKE CONTROLS DESCRIPTION AND OPERATION
Some trucks less than 3900 Kg (8600 lb) GVW with a gasoline engine may be equipped with a Trailer Brake Control Module (TBCM) or a combination Fuel Pump/Trailer Brake Control Module (FTCM) system for electric trailer brakes. Some trucks greater than or equal to 3900 Kg (8600 lb) GVW may be equipped with a integrated Trailer Brake Control Module (TBCM) system for electric trailer brakes. The power output to the trailer brakes is based on the amount of brake pressure being applied in the vehicle’s brake system. The available power output to the trailer brakes can be adjusted to a wide range of trailering situations.
NOTE: Connecting a trailer that is not compatible with the trailer brake system may result in reduced or complete loss of trailer braking. There may be an increase in stopping distance or trailer instability which could result in personal injury or damage to your vehicle, trailer, or other property. An aftermarket controller may be available for use with trailers with surge, air or electric-over-hydraulic trailer brake systems. To determine the type of brakes on your trailer and the availability of controllers, check with your trailer manufacturer or dealer. Do not power-up an aftermarket controller with the factory brake controller at the same time.
The vehicle is equipped with the following trailer braking components:
- Manual Trailer Brake Apply
- Trailer Gain Adjustment
- Trailer Brake Control Panel
- Trailer Brake Driver Information Center Display
The Trailer Brake Control Module (TBCM) or a combination Fuel Pump/Trailer
Brake Control Module
(FTCM) can support up to a maximum of 4 axles with electric trailer brakes (8
brake magnets).
