Hello all. My 96 Deville throws the RS0038 code. for the rear ELC. I cannot find the description for the code at this time but I know it has something to do with the compressor. I have run into this cde many times before on other Cadillacs and usually the ELC fuse in the trunk pops and the compressor does not operate. But this one is not happening like that. here is what I have for info. Car rides fine No other codes present Have never gotten a service ride control message Air compressor works fine and exhausts fine rear suspension does not change when vehicle sits for extended period of time. Not quite sure why this code is occuring as suspension seems to be working properly. Only one time I had about 700 lbs in back seat and rear suspension rode low. definately lower than normal. I use the spokes of my rims as reference of ride height. Normal ride height I can see the holes in the spokes at the top of the rims at the wheelwell. Which is all the time. On the ride where it rode low the rear end all you could see was half of the center cap. Yes thats very low. but still rode great. and got decent mileage. I would appreciate any insight on this topic. I plan to purchase a spare compressor to rebuild and install someday. But at this time I am not too worried about the problem. the code has been coming up for awhile and the only reason why I know its there is because I run the codes once in awhile and it is the only code. Whatever is causing this code only seems to be affected by heavy load in the rear end. other than that it rides perfectly normal. thanks all
