How do you check the air suspension on a 2012 Ford Expedition?

Checking the Air Suspension on a 2012 Ford Expedition
To check the air suspension on a 2012 Ford Expedition, you can follow these steps:
1. Inspect the Ride Height: Start by visually inspecting the ride height of your vehicle. If you notice that the rear of the vehicle is sagging or lower than normal, it could indicate a problem with the air suspension system.
2. Check for Warning Lights: Look for any warning lights on the instrument cluster indicating an issue with the air suspension system. The “Check Air Suspension” light may illuminate if there is a fault detected .
3. Perform a Reset: In some cases, resetting the air suspension system may resolve minor issues. To reset the system, you can try disconnecting the battery cables and letting the vehicle sit for about 30 to 60 minutes. This will allow the charge to dissipate from the computer, forcing it to reset the air suspension. However, please note that this method may also reset other settings in the vehicle.
4. Scan for Fault Codes: If the issue persists, it is recommended to use a scan tool to check for any fault codes related to the air suspension system. A scan tool can help identify specific issues such as air leaks, a failing compressor, malfunctioning sensors, or worn/damaged air springs.
5. Inspect for Physical Damage: Inspect the air suspension components for any signs of physical damage, such as leaks, cracks, or worn-out parts. Pay close attention to the air springs, compressor, sensors, and lines.
6. Consult a Professional: If you are unable to diagnose or resolve the issue on your own, it is advisable to consult a qualified mechanic or authorized Ford service center. They have the expertise and specialized equipment to accurately diagnose and repair air suspension problems.
Remember, the air suspension system in the 2012 Ford Expedition is a complex system, and it is important to address any issues promptly to ensure the proper functioning of the vehicle.
