Understanding Your 2017 Ford F-150 Tail Light with Blind Spot Monitoring
The tail light assembly on your F-150 is more than just a red lens; it’s a multi-functional unit critical for visibility and safety. For many 2017 models, this assembly integrates the advanced Blind Spot Monitoring (BSM) system, sometimes referred to as BLIS (Blind Spot Information System) by Ford. This integration makes maintaining the tail light crucial for overall vehicle safety.
The Role of BSM in F-150 Safety
The BSM system uses radar sensors, typically located behind the rear bumper and often within or near the tail light housing, to detect vehicles in your blind spots. When a vehicle enters these zones, an indicator light illuminates in your side mirror, providing a vital warning before you initiate a lane change. This feature is especially beneficial when towing, as it extends the monitored area to cover the length of your trailer.
Components of the Tail Light Assembly
A standard 2017 Ford F-150 tail light assembly includes several key components. You’ll find bulbs for brake lights, running lights, and reverse lights, often in an LED array for newer models. The lens covers these bulbs, protecting them from the elements. For BSM-equipped trucks, the radar sensor module is usually mounted internally, requiring careful handling during any service. Electrical connectors securely link the assembly to the truck’s wiring harness, ensuring all functions operate correctly.
Diagnosing Common Issues with Your F-150 BSM Tail Light
Before you jump into replacing parts, it’s essential to accurately diagnose the problem. Many issues with your 2017 Ford F-150’s tail light or BSM system can be identified with a few simple checks. Early detection can prevent more significant problems down the road.
Warning Light Indicators and What They Mean
If your BSM system is malfunctioning, you’ll likely see a warning message on your instrument cluster, such as “Blind Spot System Fault” or “Check Blind Spot System.” Additionally, the indicator light in your side mirror might remain illuminated, flash erratically, or fail to light up at all. These indicators are your first clue that something needs attention.
Visual Inspection for Damage
Begin with a thorough visual inspection. Check the tail light lens for cracks, chips, or moisture intrusion, which can affect light output and potentially damage internal components, including the BSM sensor. Look for any visible damage to the wiring harness leading to the tail light, especially if you frequently drive off-road where branches or debris could snag wires. Ensure the tail light assembly itself is securely mounted to the truck’s body.
Electrical Troubleshooting Basics
If there’s no visible damage, the issue might be electrical. A non-functioning tail light bulb could be as simple as a burnt-out filament, easily replaced. For BSM issues, a blown fuse in the fuse box can often be the culprit. Consult your F-150 owner’s manual for the exact fuse location and rating. If fuses are good, using a multimeter to check for continuity and proper voltage at the tail light’s electrical connector can pinpoint wiring problems. Remember to always disconnect the battery before working with electrical components to prevent accidental shorts.
