What does service ride control mean on a 2005 Cadillac Escalade?

If the service ride control light turns on in a 2005 Cadillac Escalade that means that there is a problem with Your suspension that was detected by the ECU. The Escalade has an air suspension in it and there can be problems that develop with the compressor, lines, or shocks. The first thing You should check is the fuse that runs the compressor and can be found in the fuse panel under the hood. The next thing to check are all the fittings to make sure they are tight from the compressor to the shocks. If those are loose usually the system will detect a leak and turn on the light.
