Understanding the Jeep Grand Cherokee Air Suspension System
Jeep Grand Cherokee Air Suspension Reset The Jeep Grand Cherokee is renowned for its rugged capability and smooth ride, largely due to its advanced air suspension system. This system not only enhances ride quality but also improves off-road performance by adjusting the vehicle’s height based on driving conditions. However, like any advanced technology, the air suspension can occasionally experience issues, necessitating a reset. Understanding the air suspension system’s mechanics is essential for any Jeep owner.
What is Air Suspension?
Air suspension utilizes air-filled bags instead of traditional steel springs to support the vehicle’s weight. This system offers several advantages:
- Adjustable Ride Height: The air suspension allows the driver to adjust the vehicle’s height, enhancing ground clearance for off-road driving or lowering the vehicle for easier entry and exit.
- Improved Comfort: By providing a smoother ride, air suspension reduces the impact of road imperfections, making long journeys more comfortable.
- Enhanced Load Capacity: The air suspension system can adjust to the load, maintaining optimal performance regardless of cargo weight.
Common Issues with Air Suspension
Despite its benefits, the air suspension system may encounter issues, including:
- Air Leak: A leak in the air bags or hoses can lead to loss of air pressure, affecting the system’s performance.
- Faulty Compressor: If the compressor fails, the system may not be able to inflate the air bags, leading to a lower ride height.
- Sensor Malfunction: The height sensors can sometimes fail, leading to inaccurate readings and improper adjustments.
In these cases, a reset may be necessary to restore normal operation.
How to Reset the Jeep Grand Cherokee Air Suspension

- Listen for the Compressor: As the system resets, you should hear the air compressor engage. This indicates that the system is attempting to recalibrate and inflate the air bags.
Test the Suspension
After the reset is complete, it’s essential to test the air suspension system:
- Check the Height: Ensure that the vehicle returns to its normal ride height. You can do this by visually inspecting the vehicle or using a height measurement tool.
- Drive the Vehicle: Take your Jeep for a short drive, paying attention to how it feels over bumps and uneven surfaces. The suspension should respond appropriately, adjusting to the road conditions.
Address Any Remaining Issues
If the air suspension system does not function correctly after the reset, further troubleshooting may be required. Here are some potential next steps:
- Inspect for Leaks: Check the air bags and hoses for any signs of damage or wear. A visual inspection may reveal leaks that need repair.
