2017 Ford F150 Tail Light With Blind Spot
The 2017 Ford F-150 represented a significant leap forward in truck technology, and one feature that often gets overlooked yet provides substantial safety benefits is the availability of Blind Spot Information System (BLIS) integrated with the tail lights. This article delves into the specifics of the 2017 F-150's tail light design incorporating BLIS, its functionality, potential issues, and considerations for repair and replacement.
Blind Spot Monitoring: Beyond Just Mirrors
Blind spot monitoring systems are now commonplace, but the 2017 F-150's implementation, where the indicator lights are integrated into the tail light assemblies, is worth noting. Instead of having small lights on the side mirrors, the F-150 uses amber indicators located on the inner edges of the tail lights. This placement offers a clear, unobstructed view of the warning signal for the driver, particularly when changing lanes on the highway.
The system relies on radar sensors, typically located in the rear bumper. These sensors constantly monitor the areas beside and behind the vehicle, detecting when another vehicle enters a blind spot. If a vehicle is detected and the driver activates the turn signal in that direction, the amber indicator in the corresponding tail light illuminates, warning the driver not to change lanes. This integration improves visibility of the blind spot warning and enhances safety for the driver.
Understanding the Tail Light Assembly
The 2017 F-150's tail light assembly, with BLIS, is more complex than a standard unit. It comprises several components:
- LED brake lights and turn signals: Provide standard illumination for braking and signaling turns.
- BLIS indicator: The amber LED light specifically for blind spot warnings.
- Wiring harness: Connects the tail light to the vehicle's electrical system, including the BLIS module.
- Housing: The physical structure that holds all the components together, typically made of durable plastic.
It's crucial to understand this complexity when diagnosing issues. A malfunctioning tail light might not simply be a burnt-out bulb; it could indicate a problem with the BLIS system, the wiring, or even the radar sensors in the bumper.
Troubleshooting and Common Issues
Several issues can arise with the 2017 F-150's tail lights and BLIS system:
- BLIS indicator not working: This could be a faulty indicator LED, a wiring problem, a malfunctioning radar sensor, or a software glitch in the BLIS module. A diagnostic scan tool is essential for pinpointing the cause.
- False BLIS alerts: This can be caused by dirty or obstructed radar sensors, sensor misalignment, or interference from other electronic devices.
- Complete tail light failure: A blown fuse, damaged wiring harness, or a faulty ground connection can cause the entire tail light assembly to stop functioning.
- Water intrusion: Cracks or damage to the tail light housing can allow water to enter, causing corrosion and short circuits.
When troubleshooting, start by checking the fuses related to the tail lights and BLIS. Next, visually inspect the tail light assembly and wiring for any damage. A scan tool that can read Ford-specific codes is invaluable for diagnosing BLIS-related problems. Often, mechanics will recommend recalibrating the radar sensors after repairs or replacements to ensure accurate performance. Keep in mind, improper calibration can render the BLIS system ineffective.
Replacement and Repair Considerations
Replacing a 2017 F-150 tail light with BLIS requires careful consideration. Aftermarket options are available, but ensure they are DOT-approved and compatible with the BLIS system. Cheaper alternatives might lack the necessary wiring or functionality for the BLIS indicator. It is highly recommended to use OEM (Original Equipment Manufacturer) parts to avoid compatibility issues and ensure proper system operation.
The replacement process typically involves removing the tail light assembly from the truck bed, disconnecting the wiring harness, and installing the new unit. Remember to secure the wiring harness properly to prevent it from rubbing against the body or other components. After the replacement, test the BLIS system to ensure it is functioning correctly. A professional mechanic can perform the replacement and any necessary recalibration, guaranteeing the system's proper operation.
The cost of a replacement tail light assembly with BLIS for the 2017 F-150 can range from $300 to $600, depending on whether you choose OEM or aftermarket. Labor costs for installation will add to the total expense. Regular maintenance, such as cleaning the radar sensors, can help prevent problems and extend the life of the BLIS system. Keep your vehicle well-maintained to enjoy many more years of safe driving, and remember to regularly inspect your tail lights.
