1991 Cadillac Deville Trouble Codes

Hello! I'm back again since my caddy insists on being bad. I've got some codes that popped up. one was teh EE E48 code which i understand is the EGR system(i know i need a new EGR valve). The other is an F32, F48, and F31 code. If anyone can help with identifying the F codes it would be fantastic. Unfortunately all the code sites i've found do not list F codes.
Any help would be appreciated.

In regards to the F32 code when you said HARD code does that mean that since it went off that the PCM-BCM is a major issue right now?
What do you mean "it went off"? No longer displayed in the readout? Did you perform some type of action?
A 'hard' code means it has been the history and is not a intermitent(transitory) code
Data codes mean there is a communication problem between the units. Maybe something isn't connected properly/a high resistance connection, the data is outside of parameter specs or no data at all.
