The Ford Trailer Tire Pressure Monitoring System (TPMS) is a feature designed to enhance safety and convenience for trailer owners. It allows for real-time monitoring of tire pressure in trailer wheels, which is essential for maintaining performance, preventing blowouts, and ensuring proper load distribution. When combined with a rear-facing trailer camera, the system becomes an integral part of modern towing technology, offering visibility and control that was previously unattainable.
From the experiences shared in online forums and user installations, the TPMS module, camera, and wiring harness are typically included in an OEM kit. Installation often involves replacing the bumper-mounted plug with a new one provided in the kit and connecting the TPMS receiver and camera to the trailer. Despite the lack of detailed instructions in many kits, users have reported that the installation process is straightforward and intuitive.
This article explores key aspects of the Ford Trailer TPMS installation, including mounting considerations, user experiences, compatibility, and practical advice drawn from verified user reports and forum discussions.
Understanding the Ford Trailer TPMS Kit
The Ford Trailer TPMS kit is typically sold as an optional add-on for vehicles equipped with towing packages. According to user reports, the kit includes the following components:
- A TPMS receiver module
- A rear-facing trailer camera
- A wiring harness and connectors
- A 7-pin to 5-pin adapter
- Internal TPMS sensors (typically four, though some users with multi-axle trailers require more)
The module is responsible for receiving signals from the TPMS sensors installed in the trailer tires and transmitting the data to the vehicle's infotainment system. The camera provides a live video feed to the Sync screen, enhancing visibility when backing up or maneuvering the trailer.
Users have noted that the kit is often specific to certain vehicle models and years. For example, the 2022 F-150 model is reported to use a kit with part number ML3Z-1A189-E, while Super Duty models may share similar components. However, the exact part number and compatibility should be verified with the dealer or manufacturer documentation.
Installation Overview and Practical Tips
Installation of the Ford Trailer TPMS kit involves both vehicle-side and trailer-side components. According to multiple user reports, the process is generally straightforward and does not require advanced technical skills. The following are key steps and considerations:
Vehicle-Side Installation
Replacing the Bumper Plug
The vehicle-side installation typically involves replacing the existing bumper-mounted plug with a new one that includes the necessary connectors for the TPMS and camera. This plug is often a combined unit, with the 7-pin and 5-pin connectors integrated into a single housing.Connecting the Cable
The TPMS receiver and camera cable is connected to the new bumper plug. This cable runs from the rear of the vehicle to the trailer and is usually long enough to accommodate trailers over 30 feet in length.Camera Setup
The rear-facing camera is typically mounted on the trailer tongue or frame, depending on the trailer design. The camera must be positioned for optimal visibility and should be connected to the wiring harness.
Trailer-Side Installation
Mounting the TPMS Module
The TPMS module must be mounted in a location that provides a clear line of sight to the trailer wheels. Forum users have reported mounting the module in the front pass-through area of the trailer, about 13 feet forward of the first axle. As long as the module's antenna is not obstructed, it can be mounted on a frame crossmember or in another accessible location.Installing the TPMS Sensors
The TPMS sensors are installed inside the trailer tires. Some users have had their tire dealers handle this process, particularly when replacing tires. The sensors are typically installed during tire mounting and are not visible once the tire is inflated and mounted.Connecting the Harness
The wiring harness from the TPMS module is connected to the TPMS receiver and camera. The harness is often long enough to reach from the module to the camera and receiver, even in larger trailers.Testing the System
Once the installation is complete, the system can be tested by connecting the trailer to the vehicle and checking the Sync screen for the camera feed and TPMS readings. Some users have reported that the setup process is similar across F-150 and Super Duty models, and that no special calibration is required.
User Experiences and Common Considerations
Several users have shared their experiences with the Ford Trailer TPMS installation, highlighting both successes and challenges. The following are some of the key insights:
Mounting the Module
One user installed the TPMS module in the front pass-through area of a 32-foot trailer and reported no issues with signal reception. Another user recommended mounting the module on the back side of a crossmember to avoid obstructing the antenna.Installation Time
Multiple users reported that the installation took less than five minutes for the vehicle-side components and a couple of hours for the trailer-side setup. The lack of detailed instructions in the kit was noted, but many users found the process intuitive.TPMS Sensor Installation
Some users had their tire dealers install the TPMS sensors during tire mounting, which saved time and ensured proper installation. Others installed the sensors themselves or found that the sensors were included in the kit.Camera Performance
The rear-facing camera was described as providing an excellent view on the Sync 12-inch screen. The camera is often mounted on the trailer tongue and is said to offer clear visibility when backing up or maneuvering.Compatibility and Issues
A few users reported challenges with dealership staff and parts availability. One user mentioned that the parts person incorrectly believed the kit included a yaw sensor, which was not the case. Another user noted that the instructions provided were of poor quality and lacked important details.Cost and Value
The cost of the kit varied depending on the dealer and location. One user reported paying approximately $400 for the installation on a 22-foot trailer, including labor and materials. Another user noted that the system was a "breeze" to install and provided significant value in terms of safety and convenience.
Practical Advice for Installation
Based on the experiences shared in the forum discussions, the following are practical tips for installing the Ford Trailer TPMS:
Plan the Mounting Location
Choose a mounting location for the TPMS module that provides a clear line of sight to the trailer wheels. Avoid locations that may obstruct the antenna or cause signal interference.Ensure Proper Cable Length
Verify that the wiring harness is long enough to reach from the TPMS module to the camera and receiver. Most kits are designed for trailers up to 30 feet or more, but it's always a good idea to confirm.Install the TPMS Sensors Correctly
If you are not installing the sensors yourself, consider having a tire dealer handle the installation. This ensures that the sensors are properly placed and functioning.Test the System After Installation
Once the system is installed, test it by connecting the trailer to the vehicle and checking the Sync screen for the camera feed and TPMS readings. This will help identify any issues before towing.Document the Setup
Keep a record of the installation process, including the mounting location, wiring connections, and any modifications made. This can be helpful for troubleshooting or future reference.
Conclusion
The Ford Trailer TPMS is a valuable addition for trailer owners, offering real-time tire pressure monitoring and enhanced visibility with a rear-facing camera. Installation is generally straightforward, with many users reporting that the process is intuitive and does not require advanced technical skills.
