check suspension light is on continuously. also what does the suspension switch in the back do?
If you have a "check suspension" light, then you must have the optional air suspension system on your Explorer. This light is turned on when a problem with the air suspension system is noticed by the control module. The air suspension system uses a computer controlled air compressor to inflate air springs in the rear to control vehicle height and ride quality. There are many possible causes for a problem in this system, including a compressor not operating correctly, one of the various sensors in the system not working properly, an electrical problem, or an internal control module fault.. That switch turns off the compressor, it need to be off when ever the car is jacked up to change a tire or whatever To find out what is wrong, a scan tool with software capable of communication with this system is needed. When the light was turned on, fault codes related to the problem were stored in memory,; retrieving this stored diagnostic information is an essential first step in diagnosing the fault. Then, the factory scan tool will be required to test the system to determine the exact problem and to verify repair afterwards.
