What Is FCW System?
The FCW system uses your car’s sensors to monitor the roadway ahead for obstructions, like other cars, immovable obstacles, and even people. FCW detects the distance and speed of your vehicle and surrounding objects as you drive. If your vehicle approaches too near for you to use the brakes in an emergency efficiently, this technology alerts you of a probable collision.
According to studies, this technology reduces rear-end accidents by 27%. In modern vehicles, a combination of FCW systems and automatic emergency braking units is possible. You’ll need to consult your owner’s handbook to learn about the safety features installed in your car. Regardless of all safety features, you are always accountable for your driving and habits while on the road.
How Does FCW System Work?
Your FCW system uses sensors to identify impending collisions. These sensors could include a front camera, lasers, or radar. FCW technology will alert you when a crash is determined; an alert can be an audio alarm, a visual indicator, or steering wheel vibrations. Such an alert aims to provide you with time to prevent the accident. In rare instances, the system can automatically engage the brakes if it senses an impending collision and you fail to take appropriate action.
However, in your Driver Assist System Setup menu of your car’s infotainment system, you can choose between short, regular, and long forward-collision warning distance settings for the minimum range your FCW system alerts you. When you notice an “FCW System Failed” alert, bad weather is likely the reason. According to your vehicle’s service manual, your FCW system could provide a misleading signal while driving in rainfall, snow, mud, fog, or high heat. Stop your car when it’s safe and switch off your engine.
Primary Features of the FCW System
Your Forward Collision Warning system may prevent a possibly expensive or life-threatening accident for you and your car. Among the essential elements of your FCW system are:
- Identifies automobiles, bicycles, motorcycles, and even people
- Day and night operation
- Can scan your path about 20x per second
- Sensors can detect up to 500 feet ahead of your car
- Allows approximately five seconds of response time
- It doesn’t work at speeds under three miles per hour to prevent unwanted warnings
What Does The FCW System Failed Mean?
If you’ve gotten in a car crash, you might have encountered the words “FCW system failed.” It refers to your frontal collision warning system and is a function of some automobiles intended to avoid collisions. This technology functions to assist you in avoiding collisions by delivering an alert when it identifies a possible crash.

FCW Sensor Location
Your FCW system measures the distance to the car in front of you using its distance sensor, usually situated under your front bumper. The “vehicle ahead detection indicator” flashes, and a warning tone plays once the system determines that your car is approaching the automobile ahead. If you’re uncertain about the location of your FCW sensor, check your owner’s handbook.
Have your technician or car dealer recalibrate your radar sensor if the notice “FCW Front Radar Temporarily Blocked” appears regularly without rain, snow, dirt, mud, or any similar blockage. Also, it’s better not to install a front-end protection, snow plower, aftermarket grille, or grille modification. This could prevent your sensor from functioning and impede FCW performance.
Reasons Why FCW System Fails

While typing or viewing text messages, drivers take their attention away from the road for about five seconds, equivalent to traversing the length of a whole football pitch at 55mph. In addition to phones, snacking and operating the car’s navigation system might divert a driver’s focus off the road.
Apply The Three-second Rule
To keep a safe distance between your car and the one ahead of you, you should be aware of counting at least three seconds or longer from the time the car ahead of you passes a landmark to the time your automobile passes the same point. You must provide additional time if you run a bigger car since larger automobiles take a longer time to stop.
Don’t Drive Under Influence
Drunk driving is the cause of about one-third of all roadway deaths. Never operate a vehicle while intoxicated with alcohol or other substances that can affect your capacity to drive effectively.
