If there is a problem with the Selective Ride Control, the "Service Ride Control" light on the DIC should be on. If there is a problem and there is no light, a previous owner may have removed it.
Sometime it's hard to tell if the systemis working properly. Find a rough road and while staying at a steady speed like 50MPH, change the selector switch. You should feel an definite difference is ride quality.
The SRC system will save codes that can be pulled to determine what components are working. Try the search function and use either FX3 or SRC as search criteria. You should find some threads that describe how to pull the codes. Once you get the codes, post them here and we can help figure out any problems.
