Ok all pros. I have some questions. I got in my 01 DTS this afternoon and the DIC said "Speed limited to 90" so I looked that up and apparently that means there is a problem with the RSS system.

I then pulled the codes and here's what I saw.

IRC U1000
IRC U1016
IRC U1301
PCM U1056
ABS U1056
IPC U1016

The codes had been cleared a few weeks ago while I was learning about the system so these are all new.

What does this all mean. The error has not come back, it only happened that one time.

Thanks

This should direct you in the proper place.

In fact, It's the stickied post right above yours.


If the codes have no came back, it "may" have just been a fluke. When you pulled the codes, did they say HISTORY next to them?

I looked at that thread already and they're all communication errors. They did not say 'History' but I think they were historical codes. I'm wondering why every system in the car would have a network communications error.

Has the battery ever been pulled or fully drained? That can cause a whole slew of codes to be thrown.

I occational get a communication error for no appearent reason. Never throws a MIL or anything. I just catched it when I pull the Codes ever now and then.

Battery has not been drained or pulled since I've had the car. I'll blame it on water and write it off as a fluke. Until next time...

Thanks
