One of the car models released by Volvo is the XC90. It is a luxury SUV that is marketed in the North American market by the name of Volvo XC90. The XC90 is considered to be one of the best selling cars in the world. It has many positive reviews, and it will likely continue to sell well for many years to come.

What is Park Assist?

Park Assist is a feature that can be used to make parking easier for the car owner. It is one of the features that makes the XC90 such a lucrative deal.

 

It uses cameras and sensors to detect the distance between the car and an object, such as a wall or another vehicle. The XC90 will then apply power to the brakes, and it will move the steering wheel so that it will be in front of the object, so that it can be parked easily.

How does Park Assist work?

The Park Assist system consists of two parts: camera and sensor. The camera detects objects in front of the car, such as walls or another vehicle. This is accomplished by reading different shades of light from different colors, with infrared technology.

 

When it reads a certain shade of infrared light, it sends a signal to activate or deactivate the brakes. The sensor detects these signals and adjusts its position accordingly. As soon as there is a shorter distance between you and the obstacle, a signal will alert you with its sounds. Anything else that is played from the audio system is muted automatically.

 

Additionally, Park Assist also alerts you if you try to park too close to an object. This can cause some damage because your tires may scrape against objects that are close by.

What to Do if Your XC90 Park Assist is Not Working

The Park Assist system is built to prevent damage to your vehicle’s tires and engine. However, if the system is not working properly, you can try a few things to make it work again.

 

1) Check for any broken bumper sensors

The first thing you should do is to check the front bumper sensors. The Park Assist system will only work if these sensors are intact. If any of them are broken, it may cause the system to malfunction.

 

The bumper sensors are what lets your vehicle know if you are about to hit something. There is usually a switch in the instrument panel to turn the system on and off, and a text message or LED light to indicate that the system is currently operating. If any of them are broken, it will not work properly.

 

A bad bumper or bumper cover that is loose or misaligned can affect your system’s operation. If there is an issue with a sensor, visual inspection of the sensor may reveal a loose or out-of-position sensor.

 

You can either have them replaced or you can have the entire bumper sensor replaced by a professional. There are many car service companies that have a procedure for checking the alignment of the sensor array. There should be a test to see if the sensors are height appropriate, and another test to ensure that the sensors are able to detect objects at five points apart from the bumper.

 

2) Check if the sensors are dirty

The sensors are located in the bumper and will send a signal to the system when there is an obstacle. The signals are received by the sensor, and it will either activate or deactivate the brakes.

 

Dirt may clog up the sensors after a lot of use, or if your vehicle commonly goes through extreme weather conditions. For example, if you live somewhere where there is a lot of snow, there may be ice clogging up the sensors.

 

If there is a dirty sensor, this can cause the system to malfunction. So, you can clean the sensors with an air blower to remove any dirt particles from them. If you do not have an air blower, you can try blowing them with compressed air or water. You can also wash the bumper and the sensors with high-pressure water to determine if there is an issue with them.

 

3) Check for loose or misaligned wires

There are a few wires that are attached to the sensors. These wires are important for the operation of the system. The wires may be loose or misaligned, which can cause your system to malfunction.

 

If any of these wires is loose, it will not send a signal to the sensor. This will cause your vehicle to not move when you try to park, and it will not respond to signals from other vehicles either. If any of these wires is misaligned, it will not detect an obstacle as well as it should.

 

You can either replace these wires or have them replaced by a professional mechanic. There are also many websites that provide you with an easy-to-follow guide on how to repair your sensor wires if they become damaged or loose.

 

4) Check on the Park Assist cameras

The Park Assist system is made up of two parts: camera and sensor. The camera detects objects in front of the car. This is accomplished by reading different shades of light from different colors, with infrared technology.

 

You can test if your cameras are functioning well by having someone stand in front of your car while you try to park in a tight space where there are no obstacles in the way. You should see the indicator on your dash light up if there is an obstacle present.

 

If it does not work as intended, you can have the camera replaced by a professional.
