fcw and ldw cannot operate?
The term “FCW system failed” is one that might be encountered after an accident. It is a form of a frontal collision warning system, which is a feature that comes with many cars to help prevent accidents. If you are a Honda owner and need information on the FCW system failure, keep on reading.
Otherwise called Forward Collision System, the FCW system estimates the traffic in front of a Honda car anytime the car speed is at least 10 miles per hour. It also estimates the chances of a collision happening while providing audible and visual warnings to stop the vehicle. Simply put, it is a system that is designed to prevent collisions.
The FCW system makes use of radar, laser, or camera to scan the road ahead as it alerts the driver if an opposing driver is closing in too fast. In other words, the system detects an imminent collision by using a sensor behind the lower grille. The FCW warning light and continuous beeping represent the visual and audible cues that alert the driver.
This is not dangerous but just a safety issue. The purpose of the warning is to ensure that the driver has time to react in time and avoid the collision.
As mentioned earlier, this error is common with some Honda models. There are several reasons why the FCW system may not activate:
The FCW system’s ability to function well can be compromised by adverse weather. Driving in rain, snow, and fog can affect its camera, which is mounted in the upper part of the windshield. Droplets of water on it can cause the image to be magnified, thereby giving it a false reading.
Besides this, the presence of mud, dirt, or ice can also prevent the sensor or camera from giving accurate readings.
When you drive in an extremely hot condition, this error could occur. Hot conditions can cause camera failure.
The Powertrain Control Module (PCM) controls the mph and receives data from the countershaft speed sensor. If this speed sensor has an issue, it becomes difficult for the Control Module to receive accurate speed data from the sensor, making the FCW system fail to issue a warning.
Sometimes, people try to add accessories, including headlights, camcorders, or windshields, to their cars. However, these accessories can also affect the functions of the sensor. For instance, a windshield replacement can cause the FCW system to malfunction.
If something is wrong with the car computer, it might become difficult or impossible for it to relay messages.
Are you having an issue with your FCW system, and you wish to fix it but don’t know how? There are many solutions you can explore, depending on different causes:
It is worth stressing that it is best to prevent this error from happening before it does. With this in mind, you should ensure that your front windshield is kept clean and free of debris. This prevents an issue with the visibility of the FCW system.
If you wish to determine the warning timing or simply turn off the system, the following step-by-step guide will help you with that:
1. Click on the SETTINGS button.
2. Enter Vehicle Settings. Ensure that the vehicle must be in Park (P).
3. Click on the Driver Assist System.
4. Then, you will find a “Forward collision warning distance” mode. Click on it.
5. Select one of the following options:
6. To log out, just hit the “Back” button.
For safety purposes, you should always remember that the FCW system may not detect or identify distant objects ahead since the system’s accuracy varies with the weather, high interior heat, and other factors listed above. FCW does not necessarily come with a braking function. For this reason, you are responsible for the safety of your vehicle as you avoid collisions.
In case the FCW system fails as you are driving, you must be extra cautious while looking out for any potential hazards. You should seek immediate medical attention if you are involved in an accident.
When this happens, you should stop driving immediately. Once the Check engine light blinks, it indicates that there is internal engine damage. If this engine is blown, the possibility of it being fixed depends on the severity or the extensiveness of the damage. A few parts can be easily fixed or replaced if the damage is minimal. However, for great damage, it might be impossible to repair, and you may need to replace the engine completely.
Bad coil or spark plugs are also potential reasons why the check engine light is on. The latter is very important since it is what supplies that spark. This spark is responsible for igniting the air-fuel mixture that creates the explosion needed for the power production in your engine.
Besides this, the FCW and the LDW (Lane Departure Warning) lights tend to be on anytime the light in the check engine is on. The systems go off if the car identifies a serious engine failure. How do you fix this? You can simply follow the steps below to achieve this:
If your car does not start, it has nothing to do with the FCW system. The code you receive might indicate low voltage. Some of the reasons why your car will not start are discussed below:
This might be due to a damaged ignition coil. The coil converts the battery’s 12V into a higher voltage (25V to 30,000V) that can create a spark in the plug. When this is damaged, there is no sufficient power to do that. A multimeter – an instrument that can measure electric current, resistance, or voltage – can test how strong the coil’s current is.
Besides this, when a distributor cap is damaged, the car might refuse to start. The engine ignition coil has a voltage, which can be directed by the distributor cap to the spark plugs. If the cap becomes moist, it might become difficult for your car to start. You can wipe this out with a dry piece of cloth before reinstalling it.
Furthermore, you can check the battery connections carefully. Different tools can help in achieving this. With a Solar BA9, you can test the electrical system. It can help you simplify battery, alternator, and starter troubleshooting. This will provide you with relevant information on the condition of your battery, as well as your alternator and starter.
There have been several instances when low batteries caused the FCW system and some other warning lights to come on. You can have low batteries if your battery connections are corroded or loose. In addition, low batteries can also be caused by:
The FCW system represents an important safety feature in your car. The failure of this system is not dangerous, and this may be caused by bad weather, poor visibility, or high interior heat. You may not be aware of an impending collision if this system fails.
In this article, we will better define the FCW system for you and tell you where the sensors are located. We also outline the top causes of FCW sensor failure. At the end of the article, we discuss driving with a defective system and the reset or recalibration of the FCW system.
The FCW system is Honda’s forward-collision warning system. The FCW (Forward-Collision Warning) system utilizes sensors to determine if a collision is about to occur. These sensors can be a combination of cameras, lasers and radars. Once the system detects that a collision is imminent, it sends an alert to the driver to avoid the collision.
This alert could be an alarm, vibration of the wheel, or a visual warning. If the driver is not reacting to the message, the car can brake automatically, depending on the car model.
With this warning, the driver should be able to react and avoid an accident. However, there are times when the system needs to help the driver by providing gentle steering motions or braking to reduce speed.
The “FCW System Failed” message means the forward-collision warning system has failed in your vehicle. The FCW System is an essential safety feature meant to notify you when a collision is imminent. If the system fails, you won’t be notified of a possible collision.
Honda Accord and Honda Odyssey are two common Honda models that often suffer from the FCW System Failed message. If the FCW System Failed message occurs, it can be alarming. However, there are several instances where repair is easy.
One of the main reasons that the FCW system fails is because of bad weather. If you are driving in extreme rain or snow, the system might misinterpret this as a possible collision and malfunction as a result.
In this case, the only solution is to pull over and wait for the weather to pass. We recommend turning off the engine for a few minutes to let the system reset.
If you have driven on a muddy road or haven’t washed your car for a long time, it can cause the FCW system to fail. If the camera or radar sensor is covered in dirt or mud, it will not work properly and you will see this error on your dashboard.
Clean your car or the area in front of the camera or radar sensor.
As with any car part, these sensors can wear down over time. That’s why it’s important to have the vehicle regularly inspected and looked at.
Maybe you can’t see any major damage to the sensors, but they still need to be replaced. Someone qualified to work with these advanced safety systems will know what’s going on.
It’s possible for the sensors or camera to fail prematurely or for no reason at all. Even if you have taken care of your vehicle, the sensor can die and malfunction all on its own.
If the sensor or camera detects collisions that aren’t there, or it fails and sends you a dashboard message, you want to have it looked at. The only way to remain safe is to fix it promptly.
Sometimes it’s not the sensor that has failed, but the software running it. There is software installed to run the FCW system that is prone to failure.
Some automakers can provide an update to correct the situation. Otherwise, it will need to be reprogrammed.
The FCW system can fail if damage has occurred. If you’ve been in an accident, the sensors might have sustained damage that renders them inoperable.
It’s important to have the vehicle looked at after any collision, no matter how small it is. Once you get the okay from a mechanic, you are good to go again.
Each make and model has FCW sensors in various places. In most cases, you can find the sensors in the front of the vehicle, since this is where collisions occur.
The sensors can be found near the headlights or in the grille. If cameras are involved in the system, these might be on or near the windshield. You can get more information from the owner’s manual.
We’ve discussed how important the FCW system is to your on-road safety. If it fails, you are putting yourself and your occupants in danger. You won’t be alerted if there’s a possible collision up ahead, leaving you on your own to navigate the road.
While you can drive without the FCW system working, it’s best not to. We prefer that you have it repaired right away to ensure the safety of everyone around you. However, we also understand that you might need to drive a little bit to get to the service center. During this time, take your time and be extremely cautious since you are driving unprotected.

To reset the advanced safety system, you will need the help of a professional that has high-tech scanners. Most code scanners aren’t able to reset the system and it can’t be done from the vehicle itself.
The mechanic will use their calibrated tools to turn off the warning light. Once the problem is resolved, the light shouldn’t come back on.
Some people recommend resetting the ECU to reset the system on its own. This would be done by disconnecting the battery for thirty minutes. However, we don’t recommend this method because of the inconvenience it can cause with other systems in your vehicle.
If you’ve had your windshield replaced or a front body part put on, you might need to have the FCW system camera recalibrated. With the help of dynamic or static camera aiming, the system will be good to go once again. This aiming process is done at a professional shop only.
The cameras must be aimed at specific targets according to the factory specifications in the service manual. The auto repair shop will put on the parking brake and turn off both the DRLs and headlights before starting. It must also be done in a garage where natural light sources aren’t interfering.

The cost to repair the FCW system failure depends on what needs to be done. If the sensor simply needs to be cleaned off, you may only spend $75 or so. On the other hand, major failures could quickly add up to $1,500 or more. This isn’t a cheap system to work with.
Not only does it matter what has caused the problem, but your make and model of the vehicle will also influence the price. A cheap, economical car might not cost as much to repair as a luxury model. Plus, some luxury brands require special mechanics to work on these systems. You would have to visit a particular dealership or another repair shop that is certified to work on your vehicle type.
In some cases, you might be able to perform the repair on your own if you have the right equipment. However, the scanner needed to recalibrate or reset the system is expensive and not something most home mechanics have. For this reason, it might be better to bite the bullet and visit your local repair shop instead.

This week I’ve been cruising in the new GMC Terrain. And this Terrain is equipped with the most advanced safety features and accident prevention equipment on the market; GM’s forward collision warning (FCW) and lane departure warning (LDW) system. It turns out this simple, relatively inexpensive system makes a big impact.
The simplicity stems from the fact that the entire system utilizes one high-resolution camera to function. The camera is mounted in the windshield, on the right side of the rear-view mirror. The camera constantly takes four different pictures and runs them through algorithms to determine where the lanes are on the road and the relative distance and speed of a vehicle in front of the car. By comparison, most forward collision systems utilize radar on the front of the vehicle – usually the same radar utilized by adaptive cruise control systems.
The hardware’s simplicity leads to the headline of the system: it’s only a $780 option. So, is it worth it?
Short answer, yes. Both the lane departure warning and forward collision assistance work really well. Here are some notes I’ve taken during the last week regarding the system:
