If you’re a Jeep Grand Cherokee owner, chances are you’ve experienced some issues with the air suspension system.
While this system is great for providing a smooth ride and improving off-road capability, it can sometimes act up.
Fortunately, resetting the air suspension isn’t as complicated as it sounds.
Whether your Jeep is sagging or the system isn’t responding, resetting it can often solve the issue and get you back on the road.
I’ve been through this process myself, and I know how frustrating it can be.
So, let me guide you through how to reset the air suspension on your Jeep Grand Cherokee, so you can get your ride back in top shape.
What is Air Suspension on the Jeep Grand Cherokee?
Before we dive into the reset process, let’s quickly cover what air suspension actually is and why it’s important.
The Jeep Grand Cherokee comes with an optional air suspension system, which helps provide a smoother ride, especially over rough terrain.
Unlike traditional steel coil suspensions, air suspension uses air-filled bags instead of springs. This allows for adjustable ride height, improved comfort, and better off-road capability.
If your Jeep’s air suspension isn’t working properly, it can affect the vehicle’s height adjustments, ride quality, and overall driving experience.
Luckily, resetting the system can often resolve these issues.
Signs You Need to Reset the Air Suspension
Before we go into the reset process, it’s helpful to know when it’s time to reset your Jeep’s air suspension. Here are a few common signs:
Sagging or uneven height: If your Jeep’s suspension is sagging on one side or not raising to the correct height, it’s a sign that the system may need a reset.
Warning lights on the dashboard: If you see the “Suspension System Fault” or similar warning light on your dashboard, it could indicate an issue with the air suspension system.
Rough ride quality: A noticeable drop in ride comfort or handling could be a sign that your air suspension system is malfunctioning and may require a reset.
Inability to adjust ride height: If you can’t change your Jeep’s ride height, it’s likely a problem with the air suspension.
How to Reset the Air Suspension on Your Jeep Grand Cherokee
Now that we know why you might need to reset your air suspension, let’s go over the steps involved in the process.
Here’s a simple, easy-to-follow guide that will help you reset the air suspension system on your Jeep Grand Cherokee.
1. Turn Off Your Jeep
Make sure your Jeep is completely off before you begin. Turn off the ignition and remove the keys. This is a simple but essential step to avoid any electrical issues during the reset.
2. Locate the Air Suspension Control Switch
Most Jeep Grand Cherokees with air suspension will have a control switch or button for adjusting the ride height. This switch can be found inside the vehicle, usually near the center console or the dashboard. On some models, you may need to refer to the owner’s manual to locate it.
3. Reset the System Using the Control Switch
Once you’ve located the air suspension control switch, press and hold it for about 10-15 seconds. You may hear a slight noise, or the suspension might start to adjust. This indicates that the system is resetting itself.
4. Wait for the System to Complete the Reset
After holding the switch for 10-15 seconds, release it. The system will go through a short diagnostic process. During this time, you may notice the vehicle’s ride height changing, as the air suspension adjusts itself to the correct position. Wait until the vehicle stops moving and the air suspension has fully reset.
5. Check for Warning Lights
After the reset, check your dashboard for any warning lights. If the air suspension has been reset properly, the warning light should turn off. If the light remains on, there might be an underlying issue that requires professional attention.
6. Test the Ride Height Adjustments
Finally, test the air suspension by using the control switch to adjust the ride height. Ensure that it moves up and down as expected. If it does, the reset was successful.
Can You Lift a Jeep Grand Cherokee with Air Suspension?
One of the benefits of air suspension is its ability to adjust the ride height, which means you can lift or lower your Jeep Grand Cherokee to suit different driving conditions.
When off-roading, for example, you might want to raise the suspension to increase ground clearance.
If you’re just cruising on the highway, you can lower the suspension to improve aerodynamics and ride comfort.
So, yes, you can lift your Jeep Grand Cherokee with air suspension. This is one of the key advantages of having an air suspension system over traditional coil springs – the ability to adjust the ride height based on your needs.
Does Jeep Grand Cherokee Have Air Suspension?
Many Jeep Grand Cherokee models are equipped with air suspension, but it’s usually available on higher trims, like the Overland and Summit models, or as an optional feature.
Air suspension offers several advantages, such as improved ride quality, adjustable height, and better off-road capability.
However, if you own a base model, your Grand Cherokee might come with a traditional suspension system instead.
If you’re not sure whether your Jeep has air suspension, check your vehicle’s specifications or the owner’s manual for details.
