What does the error code E30 mean on the 1987 cadillac sedan deville?

Ive checked my error codes since I keep getting different engine lights coming on in my cadillac. I have the error code E30, E48, E63, F41 and F46, I would like to know what they all mean if anyone knows. Thankyou|||E30 - ISC RPM Out Of Range


E48 - EGR System Problem


E63 - Cruise Set vs. Vehicle Speed Too High


F41 - Cooling Fans Problem


F46 - Low Refrigerant Charge





It sounds like you have a variety of problems, I don't really see any link between these but a Cadillac mechanic may have seen some of these with a common cause.
