2019 Ford F350 Tail Light With Blind Spot Detection
This guide provides essential information on handling the 2019 ford f350 tail light with blind spot detection, covering common electrical issues, sensor calibration, and safe removal procedures. Whether you are dealing with a cracked lens or a malfunctioning BLIS system, these steps will help you restore your truck’s safety features.
You rely on your Ford Super Duty for heavy towing and long hauls, but a damaged tail light assembly can compromise more than just your visibility. Because the 2019 ford f350 tail light with blind spot detection houses sensitive radar modules, a simple repair can quickly become a complex technical task.
If you have noticed warning lights on your dash or are looking to replace a damaged housing, you have come to the right place. In this article, we will break down the intricacies of the Blind Spot Information System (BLIS) and provide a clear roadmap for handling these sophisticated components safely.
Understanding the 2019 ford f350 tail light with blind spot detection System
The tail light assembly on a 2019 F-350 is not just a piece of plastic and a bulb. It serves as the housing for the radar-based blind spot sensors that monitor vehicles in your adjacent lanes.
These sensors operate by sending out radio waves to detect objects. When you damage the tail light housing, you risk misaligning or breaking these delicate internal sensors, which can trigger a service required message on your instrument cluster.
It is vital to understand that the sensor module is typically mounted to the back of the tail light assembly. If you are replacing the entire unit, you must be prepared to transfer the radar module or perform a recalibration if a new one is installed.
Common Symptoms of Sensor Failure
Before you commit to a full replacement, it is important to diagnose whether the issue lies with the wiring, the lens, or the internal radar module. Most owners notice a recurring alert on the driver information screen.
- Cross-Traffic Alert Fault: Often triggered when the radar cannot “see” due to a blockage or sensor failure.
- Blind Spot System Fault: This usually indicates an electrical connection issue or a failed module.
- Intermittent Warnings: If the warning only appears during rain or heavy snow, it may be a simple case of debris blocking the sensor path.
Always inspect the physical integrity of the tail light lens first. A crack in the plastic can allow moisture to enter, leading to corrosion on the electrical pins and eventual system failure.
Tools Required for the Job
You do not need a shop full of specialized equipment, but having the right tools prevents stripped screws and broken plastic clips. Keep these items handy before you begin your repair.
- 8mm and 10mm sockets: Essential for removing the bolts securing the assembly.
- Plastic pry tools: Use these to gently release the assembly clips without damaging your truck’s paint.
- Dielectric grease: Apply this to the electrical connector pins to prevent future moisture-related corrosion.
- Torque wrench: To ensure you do not over-tighten the fasteners on the new assembly.
Step-by-Step Removal and Installation
Safety is your top priority when working with electrical components. Always disconnect the negative terminal of your battery if you are performing any wiring work to prevent short circuits.
Removing the Tail Light Assembly
Open your tailgate and locate the two bolts holding the tail light in place. Using your 8mm socket, carefully remove these fasteners and set them aside in a secure tray.
Once the bolts are removed, pull the assembly straight back toward you. Do not pull at an angle, as the plastic guide pins can easily snap inside the body panel.
Handling the Radar Module
Once the assembly is loose, you will see the electrical harness and the BLIS module attached to the rear. Carefully disconnect the harness by pressing the release tab—do not force it, as these connectors can become brittle over time.
If you are transferring the module to a new housing, unscrew it carefully. Ensure the O-ring or weather seal is properly seated when moving it to the new unit to keep the electronics dry.
Calibration and Professional Assistance
After installing a new 2019 ford f350 tail light with blind spot detection assembly, you might find that the system requires a software reset. While some modules are plug-and-play, others may need a scan tool to perform a module configuration.
If the fault light remains illuminated after installation, you may need to visit a dealership or a shop equipped with Ford-specific diagnostic software. They can run a test to ensure the radar is calibrated to the correct angle and height of your truck.
Do not attempt to bypass these safety systems. When towing heavy trailers or driving in high-traffic areas, the blind spot system is a vital tool for preventing accidents that mirrors simply cannot account for.
Frequently Asked Questions About 2019 ford f350 tail light with blind spot detection
Can I upgrade my non-BLIS tail lights to the blind spot version?
Technically, yes, but it is highly discouraged for the average DIYer. It requires adding sensors, running new wiring harnesses, and updating the vehicle’s Body Control Module (BCM) software, which is a complex and expensive process.
Will an aftermarket tail light work with my blind spot system?
Most aftermarket tail lights are designed for standard lighting and do not include the mounting points or the necessary shielding for the radar sensors. Always verify that the part is explicitly listed as compatible with the factory BLIS system.
How do I stop the “System Fault” message if the lens is not broken?
Check the wiring harness behind the tail light first. Look for frayed wires or signs of salt corrosion on the connector pins. Cleaning the pins with electrical contact cleaner and applying a small amount of dielectric grease often resolves these intermittent faults.
Is it safe to drive with a Blind Spot System Fault?
Yes, your truck remains safe to drive. However, you will lose the electronic monitoring for your blind spots, meaning you must rely solely on your side mirrors. Treat the vehicle as if it does not have the technology until you have completed the repair.
Maintaining your truck’s safety features ensures that every mile you drive—whether hauling equipment to the job site or heading off-road for the weekend—is as secure as possible. By handling your 2019 ford f350 tail light with blind spot detection with care and the right tools, you can keep your Super Duty performing at its best. Stay safe, drive smart, and enjoy the road ahead!
