DIC Code Question
Greetings all,
I've had what feels like a miss at idle in my C5. I pulled the codes, and the only one that came up is: U1064H.
Reading the doc's on this site, it says that this is "Loss of communications with DCM". Anyone who could give me some more info about this code, it would be greatly appreciated.
Thanks in advance,
Dave

Re: DIC Code Question (mac1009)
What I see a DTC U1064 is for LoCw/xxx is for the BCM -- Body Control Module, not the DCM. The DCM will be proceded by either the R or the L for Right or Left Door Control Module RDCM OR LDCM.
Since it was a H -- history code I would just clear it and see if you can pull it again in a couple of days.
BTW: I notice you are fairly new to the forum. When you make a reasonable request for help, like this, and do not get a response within 8-12 hours, post a reply to your topic that just says "TTT" or "^". This means to the top, which will bring your topic to the top of the fron page.

Re: DIC Code Question
Gary. Thanks for the advice and heads up. My left door module needs to be replaced, so I'd assume that's where it came from.
Since there's no codes for my O2 sensor, and I'm pretty much out of ideas. Does anyone have any about the rough idle. Through the RPM range, the car is fine. Once I come to a stop, it feels like I have a bad wire that's not firing or something like that. Looking at the wires, it doesn't look like they'd arc between each other, but who knows.
Thanks
