Toyota How-To: Toyota Tundra Integrated Trailer Brake Controller | Toyota


[Electronic Music] This
video will go over the Trailer Braking System equipped on the Toyota Tundra
Full-Size Pickup Truck. Since the 2016 model year,
every Tundra equipped with the 5.7 Liter i-Force V8 engine, has also included an integrated trailer brake controller system, standard. This system allows you to sync
up the brakes of a trailer equipped with electric brakes, to the braking system
of the Tundra pickup. This means that when you
apply the brakes while towing, a proportional electrical signal is sent from the brake controller,
to the braking system of the trailer behind the truck. By sharing the braking
system with the trailer, Tundra is not only able
to tow greater weights, but can do so more securely. This system uses the
Tundra’s 7-pin connector to send the braking signal to the trailer. A 4-pin connector will not work. This is because the 7-pin
connector is able to transmit up to 25 amps of
current to the trailer’s brakes. The 7-pin connector also
offers constant 12 volt power and its wiring gauge is thicker
than a 4-pin connection, which is used for lighter weight trailers without brakes or accessories. It is important to understand the controls within this system, so let’s dig into some of the details. The system information
and details are managed through the multi-information
display or MID in the center of the instrument cluster, with additional controls
located in the dashboard, to the lower right of the steering wheel. These include the gain selection buttons, and the manual trailer
brake output slider. Let’s go over the trailer
braking MID display, as well as the controls in greater detail. To access the trailer brake screen, Simply press the left or right buttons on the steering wheel MID
controls until is is highlighted. Here, you will see a
trailer connection indicator in the upper-right corner. This will light up green when
a trailer has been connected. In the center of the screen, below the truck and trailer
image, you’ll see a gain level, which ranges from 0 to 10,
in half step increments. This determines how much braking power will be routed to the trailer, With 0 being none, and 10 being maximum. It is adjusted via the
gain selection buttons on the dashboard. The next thing you’ll
see is the output meter, which provides a visual representation of the braking force as it happens. Below this, the screen indicates the type of brakes on the trailer: either electric, or
electric-over-hydraulic. This important setting ensures the proper braking force is used. To adjust this, you’ll need to go into your setup menu, also in the MID. Scroll down to Vehicle Settings, and then to the TBC trailer brake type to select the correct
type of trailer brakes. Now, there’s one other control to go over, the manual trailer brake output slider. This slider provides direct control over the trailer’s brakes, and
only the trailer’s brakes. It functions like a brake pedal, so the more you move the slider, the harder the trailer will brake. This feature is an important step in setting the proper gain level. But what if you are already
braking when you activate it? Simple, the system will
send whichever of the two signals is the strongest. You’ll need to set the
appropriate gain amount every time the vehicle load, trailer load, road condition, or weather changes. To do this, first make
sure the trailer brakes are in good, working condition
and functioning normally. Next, hook up the trailer and make the proper electrical connections. Be sure to also select the correct type of trailer brakes
that are on the trailer. Once, you’re all hooked up, drive the vehicle with
the trailer attached on a level road surface, at approximately 20-25 miles per hour. Now, using the gain selection buttons, set a starting gain of 5.0. While still driving, apply the manual trailer
brake output slider and then use the gain selection buttons to either increase, or decrease the gain to just below the point
of trailer wheel lock up. For confirmation, repeat
the previous two steps until you’re confident that the desired gain setting is reached. And that’s it. That’s all it takes to get started with Tundra’s integrated
trailer braking system. With proper control of this system, you’ll be able to tow your trailer more confidently than ever before. For more information or assistance, refer to your vehicle’s owner’s manual or visit toyota.com.

  1. time enough for Toyota tundra come with their long outstanding v8 diesel engine from Cummins not a 5.0 as previously mentioned but a 5.7 v8/7.5v8 diesel or a i6 7.5/7.0 all Cummins engines.

  2. My towing package does not work on my 2018 Toyota Tundra 5.7 crewmax. When I hook up my travel trailer the green picture light of a trailer comes on but the gain (1-10) and trailer brake output doesn’t register on the display, also when I manually press on the brake control trailer does not brake. I took the truck in twice, once in Texas when we traveled there and in Ventura ca where I bought it but to no avail. Can you help

  3. people who bought 2015 got cheated. no safety features (lane keep, dynamic cruise control), have small gas tank and freaking no trailer breaks. I wish i had waited another year

  4. I keep looking with no answer yet, towing my trailer down hill, ok if I am in tow haul mode then what? I don't want to burn up my breaks so what do I do? 2016 Trundra 5.7L SR5???????

  5. it really is a goddamn shame that many 2016+ tundra owners had to get an aftermarket brake controller system to bypass yours because it sucks that bad.
