Does the Toyota Tundra have a trailer brake controller?
Yes. The Toyota Tundra can include an Integrated Trailer Brake Controller (ITBC) when equipped with Toyota’s factory Tow Package.
What is an integrated trailer brake controller?
An Integrated Trailer Brake Controller is an on-board system that modulates the trailer’s electric brakes in proportion to the vehicle’s braking, helping stabilize the combination and provide smoother stops when towing.
Availability and how to get it
Whether the ITBC is present depends on the vehicle’s equipment. The ITBC is tied to the factory Tow Package and is not automatically included on base configurations. The following list explains common ways to verify or obtain it.
- The Tow Package, when specified for a Tundra, typically includes the Integrated Trailer Brake Controller and the wiring needed to connect to a trailer’s electric brakes.
- Many Tundra models with the Tow Package also come with the appropriate trailer wiring (such as 7-pin connectors) to support electric trailer brakes; confirm both the ITBC and wiring are included on your build sheet.
- If the Tow Package is not included on your Tundra, an aftermarket trailer brake controller and wiring kit is an option, though it won’t be factory-integrated.
For buyers, the most reliable way to confirm ITBC availability is to check the vehicle’s window sticker or build sheet and ask the dealer for the exact equipment for that model year and region.
How to use and adjust ITBC on the Tundra
When the ITBC is installed, you access and adjust it through the vehicle’s information display or a dedicated control in the dashboard. You set a trailer brake gain to match the trailer’s weight and braking characteristics, and you should test the setup in a safe area before towing.
- Enable trailer brake control and navigate to the Trailer Brake Settings in the instrument cluster or infotainment system.
- Set the trailer brake gain according to trailer weight and desired braking response; heavier trailers typically require a higher gain.
- Attach the trailer, perform a controlled light stop, and adjust the gain as needed until you achieve stable, predictable braking.
Interface and exact steps can vary by model year, so consult the owner's manual or your dealer for the precise procedure for your Tundra.
What if you don’t have ITBC?
If your Tundra doesn’t come with ITBC but you need trailer braking assistance, you have two main options: install an aftermarket trailer brake controller with a compatible wiring harness, or upgrade to a Tundra configuration that includes the Tow Package with ITBC. A professional installer can ensure proper integration with the vehicle’s electrical system and trailer connector.
Bottom line for Tundra buyers
The Toyota Tundra can offer an integrated trailer brake controller as part of the factory Tow Package, providing a seamless, vehicle-controlled trailer braking solution. Always verify the specific model year’s equipment with the dealer or build sheet, and consider aftermarket options if ITBC isn’t included in your chosen configuration.
Summary
In short, the Tundra supports an integrated trailer brake controller when ordered with Toyota’s Tow Package, enabling proportional brake control for trailers. Confirm with a dealer, review the build sheet, and consult the owner’s manual for setup and safety guidance. If ITBC isn’t included, you can pursue aftermarket solutions or consider a tow-configured model for integrated braking.
