Honda Collision Mitigation System Problem – What you should know?

You probably already know about the CMBS issue of Honda. Since around 2013, the Honda collision mitigation system problem has been the center of attention. While this breaking system was supposed to assist in preventing collisions, it’s actually leading to many problems. Whether you have already faced the problem or want to stay aware of the issues you are likely to face, this article is a must-read for you. Here, you will find out the reasons for the Honda collision mitigation system problem and what you can do to fix it. By the time you finish this article, you won’t have any confusion left. 

What Causes The Honda Collision Mitigation System Problem?

The collision mitigation system of Honda is an impressive technology. It’s an autonomous emergency braking system with obstacle-detecting sensors. The purpose of this sensor is to warn the driver of the obstacles lying ahead and trigger the brake if necessary. It’s great, right? However, there is a problem. Sometimes, the emergency brake system activates itself without any apparent reason. You are probably wondering why this happens.

Well, there are a few reasons. Check them out below:

1. The system triggers the brake if the sensor recognizes anything as an obstacle. But this sensor doesn’t work as precisely as a human eye would. It means the sensor sometimes can misunderstand something as an obstacle. It can be a speed bump, a crack on the road, or even a splash of water. Though this rarely happens, it’s a possibility. 

2. A dirty sensor will have difficulty comprehending the structure of anything that comes in its way. In such situations, the sensor is likely to recognize anything as an obstacle. In fact, if the whole sensor is covered in dirt, the entire brake system is likely to stay triggered. 

3. Broken sensors are the most common reason why collision mitigation problem occurs. If the emergency braking system of your car is broken, it will malfunction, causing the brake to trigger itself without any reason at all. The same thing can happen if the installation of the sensor is faulty. As the sensor is a sensitive component, any slight mishap can result in catastrophe here. 

Fortunately, not all Honda has emergency brake sensor. Unless you own a 2016-2020 Honda Accord, 2016-2020 Honda CR-V (EX, EL and Touring), or 2016-2020 Honda Pilot, you are good to go. But what if your bike has the sensor? 

Well, there’s no need to worry in this case because, in the next section, we will discuss the steps you can take to fix the issue with the Honda collision mitigation system. 

How To Solve Honda Collision Mitigation System Problem: 3 Things You Can Do

Having an emergency brake on a bike is very important. In fact, it is recommended you never take it off your vehicle. But what if it goes wrong and becomes a reason for an accident? If you follow the right steps, you can stop this from happening. Here are 5 things you can do to solve Honda collision mitigation system problems. 

1. Keep the sensor clean

The sensor is basically the medium for the signal to pass through. Its task is to observe whatever lies in front of it and to analyze its structure. After analyzing, the sensor determines whether to trigger the brake or not. 

To allow the sensor to function properly, it’s important to keep its vision clean. The sensor is likely to get dirty very often because of its positioning. However, a simple cleaning process should keep everything in perfect motion. 

Don’t worry. The cleaning here doesn’t involve modifying any component. Here’s what you have to do,

  • Make sure the car is stopped
  • Take a soft cloth
  • Wipe off the camera at the top by the rearview mirror
  • Wipe off the radar at the front of your car right above the license plate

And that’s in. Now, with a clean sensor, your vehicle should move smoothly. 

However, if you can’t find the camera and the radar in your car, don’t hesitate to consult the user manual. Different cars can have different positions for these parts. 

2. Reset the collision mitigation braking system

If the problem remains even after cleaning the sensors, you should try resetting the vehicle. Most of the time, the system gets jammed due to prologued use and malfunctions. However, a simple reset will fix everything. Here’s how you do it, 

  • Stop your vehicle
  • Make sure the CMS is properly hooked up
  • Make sure that the ignition is turned off
  • Restart the engine

If the problem still remains, take it to a professional. 

3. Make sure the sensors are properly installed

Well, it’s actually more of a professional task. Only they can tell if the sensor is perfectly installed in its place. The same goes for damaged or faulty sensors. Though you may notice if there is any physical damage to the sensors, the internal damages are noticeable only to expert eyes. 

So, take your vehicle to a professional and let them take a look.

It’s important to make sure your vehicle’s braking system is working properly. Horrible accidents can occur if the brake gets triggered in the middle of the road. False signals can distract the driver as well. 


Why did my car say collision warning?

The forward collision warning system basically warns you when there are some obstacles dangerously near your vehicle. You should take this warning seriously because oftentimes, it indicates something critical. Push the brake or pull over as soon as the warning sign pops up. 

Why is my collision mitigation system light on?

The collision mitigation system light may come on due to several reasons. For example, if the system is turned off, you will see the light coming on. Similarly, a blocked or dirty sensor and a faulty system also trigger the collision mitigation system light. 

Can you turn off the Honda collision mitigation braking system?

Yes, you can easily turn off the Honda collision mitigation braking system. Just keep the CMBS button pressed till a beep rings and a message pops up on the multi-information display. In case you don’t know, the CMBS button is on the steering column’s left side. 

Final Words

Having an emergency braking system is a blessing. It works like a guardian angel for you as long as it stays in sound condition. However, as you already know by now, it can misbehave sometimes. A few reasons are behind such situations. But, if you have given the article a proper read, you now should have no problem solving all kinds of Honda collision mitigation system problems that you may face. The steps mentioned in this article are proven to be effective for many users. So get right into it without any second thought.
