Unless you’re familiar with them, today’s cars have a lot of advanced safety features. The FCW System is a good example.
In this article, we are going to explain where the FCW sensors are located in order to give you a better understanding of the FCW system failure. In addition, we provide an overview of the top reasons FCW sensors fail. In the final section of the article, we discuss the process of resetting or recalibrating the FCW system depending on whether it has been damaged.
How does Honda FCW work?
A forward-collision warning system is an important safety feature on Honda cars. In order to determine whether a collision is imminent, FCW (Forward Collision Warning) utilizes sensors. In addition to cameras, lasers and radars, these sensors can be used to detect threats. An alert is sent to the driver as soon as the system detects that a collision is imminent.
A variety of alert signals can be used, such as alarms, vibrations, and visual representations. Models of cars can automatically brake if a driver does not react to a message.
An accident can be avoided when the driver receives this warning. Occasionally, though, it may be necessary to slow down the vehicle with gentle steering movements or brakes.
Can you tell me what FCW System Failed means?
Your vehicle’s forward-collision warning system isn’t working and you get a “FCW System Failed” message. You are notified when an impending collision is imminent by the FCW System. It is impossible for the system to warn you if a collision takes place if it fails.
The FCW System Failed error message is commonly seen on Honda Accord and Honda Odyssey models. FCW System Failed is an alarming message that may occur. There are, however, several cases in which the problem can be fixed easily.
Failures of FCW sensors
1. Bad Weather
The FCW system is subject to failure due to poor weather conditions. It is possible that the system can malfunction if you are driving in extreme rain or snow.
Pulling over and waiting for the weather to pass is the only option in this situation. The quickest and most efficient way to reset the system is to turn off the engine and let it sit for a few minutes.
2. Sensors or cameras that are dirty
When your car hasn’t been washed for a while or you’ve driven on muddy roads, it can fail the FCW. Dirt or mud will prevent your camera or radar sensor from working properly, leading to this error.
If the camera or radar sensor is located in the area in front of your car, it is very important to clean the area.
3. Normal Wear
Sensors can wear down over time, just like any other car part. Thus, regularly inspecting and maintaining the vehicle is essential.
In spite of the fact that they may not show any obvious damage to the sensors, you should still replace them. This type of advanced safety system is only best handled by someone who has been trained to work with it.
4. Camera or sensor failure
You can experience sensor failures or camera malfunctions for no apparent reason. A sensor can fail on its own, regardless of whether you have taken good care of your vehicle.
You could get a dashboard message if the sensor or camera detects a collision when one isn’t present. In order to remain safe, it is imperative that the problem is resolved as soon as possible.
5. Software Malfunction
Sensors fail sometimes due to software glitches rather than the sensors themselves. FCW’s operating system is susceptible to failures due to its software.
The situation can be corrected by some automakers by providing an update. A reprogramming will be required otherwise.
6. Damage
There’s a chance the FCW system will fail if there’s been damage. You might have damaged the sensors after an accident, which makes them unusable.
No matter how small the accident is, it’s important to have the vehicle checked out. As soon as a mechanic gives you the okay, you can begin using your vehicle again.
What are the locations of FCW sensors?
FCW sensors can be found in a variety of places depending on the make and model. Due to the fact that collisions typically occur in the front, the sensors are usually located at the front of the vehicle.
Near the headlights or within the grille, the sensors can be found. There may be cameras on or near the windshield if the system includes cameras. In the owner’s manual, you will find more information.
Is it possible to drive with FCW System Failed?
In our discussion of on-road safety, we discussed the importance of FCW systems. The failure of it puts your life and the lives of your passengers at risk. If a collision is imminent, you will not be alerted, which leaves you with no other option but to navigate the road on your own.
While the FCW system is not required to work, it is not recommended to do so. In order to ensure the safety of you and those around you, we recommend that you have it repaired as soon as possible. Although, we are aware that driving to the service center might be a bit of a challenge. Since you are driving unprotected, take your time and drive carefully during this time.
Performing a reset/recalibration of Honda FCW
FCW System Reset
A professional who uses high-tech scanners can reset the advanced safety system for you. It can’t be done on a vehicle itself nor can most code scanners reset the system.
When the warning light is turned off, the mechanic will use his calibrated tools. You shouldn’t see the light coming back on after the problem is resolved.
It is recommended that the system be reset automatically by resetting the ECU. The battery would be disconnected for thirty minutes during this process. This method may be convenient, but we don’t recommend that you use it because it can cause problems with other systems in your vehicle.
System calibration for FCW
The FCW system camera may need to be recalibrated if you have replaced your windshield or added a front body part. It will be possible to regain full functionality of the system once again by using either dynamic or static camera aiming. Only a professional shop can perform this aiming process.
Factory service manuals specify the targets for the cameras to be pointed at. It’ll be parked and the headlights and DRLs will be off before the work starts. Garages should be located where natural light is not interfered with.

Frequently Asked Questions
What does the FCW light mean?
It means there is a problem with the system that warns you of collisions when your forward collision warning system warning light is on. Using a code scanner can help you determine what is causing the warning light to appear, and then you can continue troubleshooting from there based on what you discover from scanning the trouble codes.
Can I still drive my car with an FCW system failure?
Yes, you can still drive your vehicle with an FCW system failure, but it’s important to be aware of the risks. The FCW system is designed to provide an extra layer of safety by alerting you to potential collisions, so driving without it requires extra caution and vigilance.
How much will it cost to fix an FCW system failure?
The cost to fix an FCW system failure can vary depending on the specific problem and the parts needed. Replacing a fuse or cleaning the camera/sensor area is relatively inexpensive. However, if the camera, radar sensor, or VSA modulator needs to be replaced, the cost can range from $600 to $800 or more. Additionally, the cost of recalibrating the FCW system by a certified technician should be factored in.
Remember, it’s always best to address an FCW system failure promptly to ensure your vehicle’s safety systems are functioning correctly and to avoid potential issues down the road.
