The SUV comes in XLT, Eddie Bauer, Limited and King Ranch trim levels. The control module will look at ambient temperature and other factors to determine when and how long the compressor should run to manage the heat.The Ford Expedition is a ladder frame full-size SUV that can carry up to nine people. The VDM control modules regulate how long the compressor will run to keep temperatures in a designated range. The system is dry and no lubricants protect the piston. What hastens the failure of the piston ring is heat. The heart of an air ride system is the piston, piston ring and cylinder. The ride height is measured and the scan tool can vent or fill the correct bag. To do this the vehicle must be on a level surface. 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.
2009 FORD EXPEDITION NAVIGATION SYSTEM DRIVER
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. These repair solutions will cover more than six-million vehicles on the road today.ĭavid Hirschhorn, Director of Brand Managementīefore starting any work, you need to disable the system through the message center. In a 45-minute webinar sponsored by CRP Automotive, the company that brings you Rein Automotive, we will cover six common cooling system repairs on BMW, Audi and VW vehicles. These solutions can simplify a repair and protect against future failures. These parts can create a win/win situation for your shop and customers when dealing with today’s vehicle’s complexity and longevity. Some replacement parts can be better than the original parts. It could be hoses, plastic couplings or water pumps. Have you ever noticed many European cars and SUVs no longer have coolant replacement intervals listed in the service information? This could be due to cooling systems requiring service or component replacement prior to that interval. Sponsored By CRP Automotive, the company that brings you REIN Automotive
