Not calibrating the ride height can result in suspension and tire damage. The Expedition’s ride height and trim can be calibrated with a scan tool. Some new vehicles, like GM, have a calibration process for the ride control system. Some enhanced scan tools can observe PIDs for the air ride system like valve operation, modes and vehicle position. Scan tools are essential for working on some systems. Criteria for these codes typically involve a ride height sensor detecting to change in suspension height if the compressor or solenoids are activated. The system will set C- or chassis codes that will be set if the system notices abnormal behavior. If you are just replacing the air spring, make sure the body of the shock is very clean. These help to seal the unit from outside debris. The o-rings on the shaft and upper mount should always be replaced and lubricated with a silicone-based spray lubricant. To deflate the spring, remove the air line from the solenoid, remove the retaining clip and rotate the solenoid counter-clockwise. Make sure you know the orientation of the upper mount and air spring before you take the assembly apart. The air bag and shock absorber can be separated. Press the RESET control to turn the air suspension OFF or ON.Select the AIR SUSPENSION function to display the current status of the air suspension system.Select the SETUP control function on the message center.Turn the ignition to the ON position, close all doors and clear warnings.The system will default to ON when the ignition key is cycled. Once the message is received, the air suspension module will take no further action to inflate or deflate the air springs.

When the driver elects to disable the air suspension system, the message center sends a message over the High Speed Controller Area Network (HS-CAN) bus to the air suspension module.
The message center is used to disable and enable the vehicle air suspension system. The system will also notify the driver of potential vehicle problems with a display of system warnings followed by a long indicator chime. Select display features on the message center for a display of sta tus proceeded by a brief chime. The message center is located on the instrument cluster and displays important information through a constant monitoring of vehicle systems. Replaces O.Before starting any work, you need to disable the system through the message center.
