Honda FCW System Failure – Meaning – Reasons – Troubleshooting

Find out what causes the “FCW System Failed” warning and how to rectify it in your Honda.

This article will help you better understand the FCW system by defining it and locating its sensors. Moreover, we list the most common reasons why FCW sensors fail. Finally, we cover how to fix a malfunctioning FCW system and how to get back on the road after resetting or recalibrating it.

To resolve the FCW system error message, first park your vehicle in a safe location and turn off the engine. Allow the engine to cool for ten to twenty minutes before trying to restart it. By doing so, the FCW system failure warning will be removed, and the system will be reset.

Exactly What Is The Honda FCW System?

Honda’s pre-collision safety technology is called FCW. The Forward Collision Warning (FCW) system uses sensors to detect when a potential collision is imminent. Cameras, lasers, and radars are all viable options for this class of sensors. When an accident is about to occur, the system will inform the driver so that they can take preventative measures.

The warning could be audible (through an alarm) or tactile (by wheel shaking) or visual (via flashing lights). Depending on the model, the automobile may apply the brakes automatically if the driver does not respond to the alert.

The driver will be alerted in time to take corrective action and hopefully avoid an accident. In some cases, though, the system will need to assist the driver by providing light steering inputs or brakes to bring the vehicle’s speed down.

What Does It Mean When It Says “FCW System Failed”?

If you see the message “FCW System Failed,” that signifies your car’s forward collision warning system has malfunctioned. The Forward Accident Warning System is an important safety feature that sounds an alarm before a collision occurs. In the event of a system failure, you will not be warned of an approaching collision.

The FCW System Failed warning is a regular problem with Honda Accords onwards 2013 models and Odysseys 2016 onwards. There’s cause for concern if you receive the FCW System Failed alert. However, there are a few cases where fixing the problem would be simple.

Causes of FCW System Failure

Severe Weather

Fog, severe rain, snow, etc., can all lead to a bogus FCW reading. That’s because severe weather prevents the FCW sensors (Radars, Cameras, or Lasers) from doing their jobs correctly.

Typical Wear and Tear

Components are prone to wear and tear and eventual failure with time. For this reason, frequent vehicle maintenance is crucial. Preventative maintenance might uncover developing problems before they become serious.

Problems with the Software

Additionally, software problems are a common reason for FCW systems to fail. Failure of the FCW system is possible if there is a glitch in the software that regulates it. This is usually the result of a software upgrade or a problem. Keep your car’s software up-to-date by installing updates frequently.

Sensor Failure

One of the things that can go wrong with an FCW system is a defective sensor. The system may fail if the collision detection sensor is broken or not functioning properly.

Damage 

The FCW system can fail if the vehicle is physically damaged. If the sensor were to become damaged, say in an accident, it could become itself useless.

Taking your car to repair is the only surefire way to find out whether the sensors are broken.

Where do you find the FCW Sensor?

FCW sensors can be found in a variety of locations on each model and brand. Since front-end collisions are more common, this is typically where you’ll find the vehicle’s sensors installed.

The sensors are installed in the grille or next to the headlights. Cameras, if they are a part of the system, may be mounted on or near the windscreen. The manual is where you can find out additional information about the device.

How Safe Is It to Drive If My FCW System Has Failed?

The FCW system is crucial to your safety when driving, as we have described. There is a risk of harm to you and the others inside if it fails. Since you won’t be warned of an impending crash, you’ll have to keep an eye out for it yourself.

Of course, you can get behind the wheel even if the FCW system isn’t functioning, but you shouldn’t. For the sake of everyone around you, please have it fixed as soon as possible. We do realize, however, that you may have some travel time before reaching the service center. Since you are exposed on the road at this time, you should take it slow and be extra careful.

How Do I Reset FCW System Failed?

Here is How to Reset FCW System:

First, choose a safe area to park your vehicle and turn off the engine. To restart the engine, give it ten to twenty minutes to cool off. By performing this action, the FCW system failure notification will be removed, and the system will be reset. The DRL system is connected to it.

Try The Other Methods Listed Below If This Doesn’t Work:

The sensor camera may overheat in extremely hot conditions, resulting in the display of an error message.

• To do this, activate the air conditioner and direct it to the windscreen where the camera is installed.

Faulty FCW operation may also result from the installation of powerful aftermarket interior lights or headlights.

• To fix the problem, try switching them out.

The sensor camera’s field of view can be severely impaired by dirt, debris, and stains on the windscreen.

• Make sure the sensors are in good working order by cleaning the windscreen and paying special attention to the area around the camera.

Resetting your FCW system is another option for fixing the problem.

• A Honda Diagnostic Scanner is required for this. Going to a pro to have the FCW system reset is strongly suggested.

If This Doesn’t Work:

Disconnect the Accord’s two batteries and let it sit for 20 to 30 minutes. Your car’s FCW system should be reset and the error message should disappear when you do this.

How Do I Recalibrate My FCW?

The sensors in your vehicle may need to be recalibrated if the FCW system failed error message keeps popping up.

You may need to reset the camera if you’ve recently had a windscreen replaced. The Honda service manual specifies a specific location for the camera, so you’ll need a professional to install it properly.

• If none of the above solutions work, turning off the FCW system in your Honda Accord is the last resort for getting rid of the warning. You can do this by going to the “car settings” menu and choosing either the “Driver Assist System” or “All” option.
• To disable this feature, go to the settings menu and find the Forward Collision Warning Distance option. To leave this page, click the “BACK” To top it all off, your car’s FCW system will be disabled.

How Do I Turn Off FCW In The Honda Odyssey and Honda Accord?

For more than two seconds, press the button on the wheel. There will be a beep, and the FCW indicator will stop flashing.

Cost to Fix FCW System Failure

The price tag for fixing the FCW system will rise or fall based on the nature of the damage. There’s a chance you won’t have to spend more than $85 to fix the sensor if all it needs is a good cleaning. However, big setbacks may cost you $1,200 or more in no time. Working with this system is not inexpensive.

FCW System Failed and the Car Won’t Start

The FCW system has nothing to do with your car not starting. The error message you get could be a sign of low battery power. The following are some potential causes of your car’s inability to start:

• Bad distributor cap
• Damaged ignition coil
• Poor battery connection

Frequently Asked Questions:

Which cars use FCW?

Honda’s FCW (Forward-Collision Warning) System is one example of the numerous radar collision systems on the market. This means that the FCW system is not just standard in all new Hondas but also in many other makes that have adopted Honda’s platform.

What are the reasons the FCW system failed and the Check engine light blinked at the same time?

A faulty coil or spark plug could potentially trigger the warning light. The latter is critical because it is the source of the energy that sets everything off.
