Cross Traffic System Fault [Explained!]

The cross traffic system fault is an error that appears on the dashboard of your car. It means that the car’s computer has detected a problem with the vehicle’s cross-traffic alert system, which warns you about oncoming vehicles when you’re backing up. In the rest of this blog post, I will tell you everything you need to know. Keep reading.

What is a Cross Traffic System?

The cross-traffic alert system is a safety feature built into the vehicle that alerts the driver that a car or cyclist is about to cross in front.

It will give you a visual warning and an audible alarm, so you can react accordingly. This is an important feature for any vehicle with a blind spot, If you’re not familiar with this feature, here’s how it works:

The cross-traffic alert system uses sensors on the front and rear of your vehicle to detect other vehicles in your blind spot. When another vehicle enters your blind spot, an icon will appear on your dashboard indicating that there’s another vehicle nearby.

This icon will also be accompanied by an alarm so you know to when to check your mirrors and make sure no one has accidentally entered your blind spot while switching lanes or turning at an intersection. In addition to using these sensors to detect vehicles in your blind spot, they can also be used to detect pedestrians who may step out into traffic without looking before crossing over from one side of the street to another.

How does a cross-traffic system work?

The cross-traffic system uses radar units located at the corners of your vehicle. When a vehicle approaches from any direction, the system determines whether it is a threat to your safety and alerts you if it is necessary to avoid a collision.

The cross-traffic system can also be used to help prevent accidents when making turns. When you use directional signals to indicate an intention to turn left or right, the radar unit detects vehicles approaching from behind and alerts you with an audible warning if they are too close for comfort.

What does mean when a ford says cross traffic system fault?

When a Ford vehicle says cross traffic system fault, it means that the computer has detected an error in the system, and that it is no longer turned on. This can happen for several reasons.

One of them is a bad sensor. If you notice that your vehicle does not alert you when you are backing up, then there might be something wrong with the sensor that is supposed to do so. Another reason could be a blown fuse or relay in the car’s electronic system.

The best way to diagnose this issue is by getting professional help from your local mechanic. Once they determine what is causing this problem, you will have to have them replace it with the right parts so that everything works again as intended without any problems whatsoever.

What causes cross-traffic system fault?

There are several reasons why your car’s cross-traffic alert system may not be working properly:

  • The sensor could be blocked by dirt, snow, or ice. If you try to back out of a parking space while there’s something on top of the sensors, they won’t be able to detect anything behind you. You should clear off any debris before trying to use this system again.
  • The sensor may be damaged or broken. If the wiring has come loose or if the sensor itself has been damaged, it won’t work properly no matter how much you clean it off or adjust its position. You’ll need to replace the sensor if this happens to you.
  • Your car may have a faulty computer module that controls all of its electronic systems (called an ECM). This is rare but possible if your vehicle has been exposed to water damage or electrical surges.

What Type of Sensors Does Rear Cross-traffic Alert use?

Rear cross traffic alert uses radar or ultrasonic waves to detect other vehicles in blind spots and warns you if vehicles are approaching from behind.

The system uses radar or ultrasonic waves to detect other vehicles in blind spots and warns you if vehicles are approaching from behind.

If you’re backing up, rear cross-traffic alert can help prevent accidents caused by backing out of driveways or parking spaces into moving traffic. If there are no other cars around, rear cross-traffic alert won’t activate because there’s nothing to detect!

How do I reset my rear cross-traffic alert?

If you have a rear cross traffic alert, it’s important to know how to reset the system. Here’s how:

  1. Press the Info button until you see “Cross Traffic.”
  2. Press the Reset button to turn the system off.
  3. Press the Reset button again to turn the system back on.


The cross traffic system is one of the most important features on your vehicle, is the best way to increase safety.
