Are you experiencing a pre-collision system warning malfunction in your 2018 Toyota Tundra? If so, you’re not alone. In this video, I will share my experience with diagnosing and fixing this issue, which is often triggered by the absence of the trailer brake module and control.
The Diagnosis
Upon encountering the pre-collision system warning in the 2018 Toyota Tundra, I conducted extensive diagnostics using various tools, including a scan tool that revealed the specific trouble code: U0137.
Despite thorough inspection and even replacing the camera module, the issue persisted, leading me to explore an unconventional cause for the malfunction.
The Unconventional Cause
After relentless troubleshooting, I discovered that the absence of the trailer brake module and control was the root of the problem. In vehicles where this optional feature is not installed, the pre-collision system warning may be erroneously triggered, leading to persistent alerts.
The Solution
To resolve this issue, I installed the trailer brake control and module in the 2018 Toyota Tundra. This involved locating the module behind the glove compartment, removing the necessary panels, and connecting the components with care.
Installation Process
The installation process requires precision and attention to detail. A pry tool, flathead screwdriver, Phillips head screwdriver, and a 10mm wrench were essential for accessing and installing the trailer brake control and module.
I carefully positioned the necessary components, ensuring a secure fit and proper connection. Once installed, I proceeded to reset the system and verify that the pre-collision system warning had been resolved.
Verification and Conclusion
After completing the installation and reassembling the vehicle’s interior, I verified the successful resolution of the pre-collision system warning. The vehicle was test-driven to confirm that the issue had been permanently addressed.
As a result of this discovery, I hope to assist other Toyota Tundra owners facing similar challenges with the pre-collision system warning.
Final Thoughts
In conclusion, the pre-collision system warning in the 2018 Toyota Tundra can be effectively resolved by addressing the absence of the trailer brake module and control. By following the installation process outlined in this video, you can eliminate the persistent malfunction and ensure the proper functioning of the pre-collision system.
