Computer Codes Question

I am new to the C5 and retrieved my codes of the computer. Don't know what they mean and need some translating. Here they are.

60-IPC B0516H
BO-RFA U1255H
BO-RFA U1096H
BO-RFA U1064H
BO-RFA U1016H

What do these mean?
Thanks,
Rich

U1016 Loss of Communications with PCM
U1064 Loss of Communications with BCM
U1096 Loss of Communications with IPC
U1255 Serial Data Line Malfunction
B0516 Speedometer Signal Circuit Malfunction

The "H" is HISTORY, your codes are not current.

I hope that that will help.... :flag

Helps some. By saying that the "H" is History, I assume that I can clear them and they won't come up again? How do I clear them? Also explain more on what the letters PCM, BCM IPC mean are are these bad to have these codes come up. Sorry, I am really new to this and don't understand this very much.

Re: Computer Codes Question (Rich's75)

BCM -Body Control Module
PCM - Powertrain Control Module
IPC - Instrument Panel Cluster

Yes you can clear history codes , but I'm not sure how to do it. Some one will chime in and give you the method of clearing the codes and let you know if it's a problem or just a dead battery that sent codes to the computer or just a one time glitch. Sorry I can't be of more help... Good luck.

PS. Nice looking 99HT. Check out my profile pic.

Re: Computer Codes Question (Bill Vett)

Thanks Bill. I did replace my battery about a month ago. Does that make sense?

Re: Computer Codes Question (Rich's75)

All the modules in the C5 communicate with each other.The PCM and ABS modules take priority over all others.Because of this,it is normal to have some communications codes stored in the other modules from time to time, such as RFA,IPC,LDCM,RDCM,etc...

If you have a "loss of communications" code stored in the PCM or ABS modules,then you have a problem :yesnod: ;)

Re: Computer Codes Question (Rich's75)

Rich, Go to: http://www.stengel.net/diccodes.htm This will give you all of the C5 codes and how to find and delete them. Note that "diccodes" has two "c's". If you have a copier, crank it up and have at least eight pages loaded and print the whole shebang. :D :D
