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.

E & F are the same thing. One is history I think. Someone who knows for sure will chime in.

the F is for BCM codes. the display starts with one E for the PCM history, then E.E. for current. Same sequence follows for BCM codes starting with one F for history and F.F. for current ones. F48 = refrigerant system problem. F31= Display panels to BCM problem. F32 = PCM-BCM data problem (this one has to be a HARD code, and not intermittant)
On the code E48, you can clean the EGR valve, and the EGR stack tubes under your throttle to get rid of that. EGR valves rarely need replacing.

OK, I stand corrected. It's been a long time. Thanks for the correction Amen.

Glad I could help.

Thank you.

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.

:yeah: Define "went off". a hard code would be displayed on a second pass of diagnostic codes.

In reguards to your BCM issues, do the fuel read-out and climate control screens display a small "c"? If so, your Body Control Module is junk. I bought a used one from a salvage yard for $70. Then remove the 3 screws holding the glove box in place and slide it out. The BCM will be sitting right in front of you. there are a few similar looking brain boxes back there but this one should be the first one you see and the biggest. im pretty sure it has a purple plug in (but not positive). Once it is out, there will be a sticker on it and that will confirm that it is the BCM. Then plug the new one in, remount it and put the dash back in and problem solved
