In this guide, we’ll walk you through the steps to reset your Jeep Grand Cherokee’s air suspension system so that you can enjoy a smooth and comfortable ride.
Understanding the Air Suspension System in Jeep Grand Cherokee
The air suspension system in a Jeep Grand Cherokee comprises several components, including air springs, shocks, struts, and a compressor. These components adjust the vehicle’s height based on the driving conditions.
When you hit a bump, the air suspension system will automatically raise the vehicle to absorb the shock, and when you take a sharp turn, it will lower the vehicle to improve stability.
A faulty air suspension system can cause various problems, including uneven height, warning lights on the dashboard, poor handling and ride quality, and leaks. To avoid these issues, it is important to reset the air suspension system at regular intervals.
Symptoms of a Faulty Air Suspension System in Jeep Grand Cherokee
Just like any other vehicle component, air suspension can suffer from faults. Here are some of the symptoms of a faulty air suspension system in a Jeep Grand Cherokee.
- Reduced Ride Height: The first symptom of a faulty air suspension system is a reduction in ride height. You may notice that your Grand Cherokee sags more when parked than it did previously, and if the ride height is significantly lower, it may affect the handling of your vehicle.
- Unusual Noises: Another symptom of a faulty air suspension system is unusual noises coming from the air suspension system. You will hear a clicking, humming, or whining noise when you drive, or you will hear a loud bang if the system is completely failing.
- Lack of Comfort: With a faulty air suspension system, you may experience a decrease in ride comfort. The suspension may no longer be able to absorb bumps and dips in the road, and this can make your ride feel bumpier and less comfortable.
- Uneven Tire Wear: If your air suspension system fails, it can cause uneven tire wear. This can cause your tires to wear out faster and require replacement sooner than expected.
- Uneven Ride Height: An uneven ride height is one of the most obvious signs that your air suspension system is failing. If one side of your vehicle is lower than the other, this is a sign of an issue with your air suspension system.
Causes of a Faulty Air Suspension System in Jeep Grand Cherokee
Sometimes things go wrong, and one of the most common problems is a faulty air suspension system. Here, we’ll discuss the common causes of a faulty air suspension system in the Jeep Grand Cherokee.
- Leaking Air Suspension Components: One of the most common causes of a faulty air suspension system is leaking air suspension components. Worn-out seals or O-rings or a damaged air suspension component can cause this. If you notice any wetness around the air suspension components, it’s important to have them checked out right away.
- Low Air Pressure: Low air pressure is another common cause of a faulty air suspension system. This can be caused by a leak in the air suspension system, a faulty air compressor, or a lack of maintenance. If your air pressure is low, you have to check it out immediately.
- Improper Installation: Improper installation of air suspension components can also be a cause of a faulty air suspension system. If your air suspension components are installed by a professional, ensure the job is done correctly.
- Faulty Sensor: A faulty or worn-out suspension sensor can also cause a faulty air suspension system. The sensor is responsible for reading the pressure in the air suspension system, and if it’s not working correctly, the system won’t be able to adjust itself properly.
- Clogged Air Filter: A clogged air filter can cause a faulty air suspension system. The air filter is responsible for trapping dirt and debris; if it’s clogged, it won’t be able to filter out the air properly.
Apart from air suspension, your vehicle can have a faulty O2 sensor. In that case, you have to know the causes and solutions for bad O2 sensor to resist future damages.
Preparation for Resetting the Air Suspension System in Jeep Grand Cherokee
Before resetting the air suspension system, it is better to consult the owner’s manual for specific instructions and precautions. You will also need to gather basic tools, including a wrench or pliers and a flathead screwdriver. Once you have everything you need, park the vehicle on level ground and turn off the engine. Let the vehicle settle for a few minutes to ensure it is completely level.
How to Reset Jeep Grand Cherokee Air Suspension?
Unfortunately, the air suspension system can malfunction continuously, leaving you with a bumpy ride. The good news is that resetting the air suspension is relatively easy and can be done in just a few steps.
1. Locate the Air Suspension Relay
The first step in resetting the air suspension system is to locate the air suspension relay. The relay is usually located in the engine compartment, near the battery.
2. Disconnect the Battery
Once you have located the air suspension relay, use a wrench or pliers to disconnect the battery. Wait for at least two minutes to allow the air suspension system to reset.
3. Wait for at Least Two Minutes
After disconnecting the battery, wait for at least two minutes to allow the air suspension system to reset.
4. Reconnect the Battery
Reconnect the battery to the air suspension relay after waiting for two minutes.
5. Turn on the Engine and Let the Vehicle Run for at Least 10 Minutes
Turn on the engine and let the vehicle run for at least 10 minutes to allow the air suspension system to initialize. During this time, the system will recalibribrate itself and adjust the vehicle’s height to its default setting.
6. Check for Warning Lights
Once the vehicle has been running for at least 10 minutes, check the dashboard for warning lights. If a warning light is present, it may indicate a problem with the air suspension system that requires further attention.
7. Check the Height of the Vehicle
After checking for warning lights, check the vehicle’s height to ensure that it is even on both sides. If the height is still uneven, it may be necessary to consult a professional mechanic for further assistance.
8. Test Drive the Vehicle
Once the vehicle’s height has been verified, take the vehicle for a test drive to check the handling and ride quality. Pay attention to any warning lights or unusual behavior during the test drive. Remember, it’s always a good idea to consult your vehicle’s owner’s manual for specific instructions and precautions.
