hello all! i joined this forum to see if anyone had any luck solving the service ride control problem! i too have a 1994 sedan deville with the same error message. i am wondering if it is telling the truth and if the problem could be a crack/leak in one of the hard plastic air lines that go to all the struts? i am going to check all of my lines tomorrow and will let you know what i find. those hard plastic air lines vs soft rubber hoses are very prone to breakage with age. does this make any sense to anyone out there?
