I'm about 50 mi away from my home base where my tools and service manuals are located. If i were there I would just hunker down and read all electrical posting here and figure this out but hope I can get an express version.
I left a store and noticed my pass window was inoperative.
Next thing I get ding ding check gauges with reduced engine power,service veh soon,abs/tc,air bag lights,tpms,and probably more that I didn't remember.
fuel,temp,gas gauges are pegged out, also getting low fuel message. The Alternator gauge still appeared to function. Also cooling fans on with climate control off.
I pulled over and checked that battery cable were tight.
Drove about 10 minutes to friends house and pulled codes. I have owned this car since March and only driven it about 700 mi.
Shut the car off and restarted without warnings except right window still inoperative.
The warnings then returned. Restarted and they were not present but reappeared.
DTC Codes are all history. I had cleared all codes several weeks ago after correcting a TPMS issue.
Sounds like a "classic" serial data bus issue !!....funny, so the chime sounds, most DIC warnings...low fuel, REP, service vehicle soon...your fuel gauge goes to empty, water temp gauge pegs out high, windows inop ...yeah buddy !!...now usually if a power or a ground (usually power) gets on the serial data line that's what you'll see...NORMALLY it will be a START AND STALL or NO START !!...your car runs right ??...if you have a bad ground say on one of the car's modules the ground has to find it's way home...it will jump on the data line to get home...Bill Curlee our resident electrical "Professor Emeritus" has documented this issue extensively here on the Forum...since it's just your Pass door there is a connector inside the rubber accordion when you open the door...since the door opens and closes many times that is where your issue may be...pull back that accordion to access the connector...look for corrosion, poor pin fitment etc. if stay happens easiest thing would be to access the passenger door module or remove the "STAR' connector next to your BCM and find the connector with the 4 or 5 wires...pull the plastic comb off it and it will isolate the passenger door module...see if that fixes it ??...I'm in the middle of filming a YouTube video covering this so stay tuned !!...hope B.C. chimes in !!
I just uploaded the first part of my "pre production"...LOL !! YouTube video so you can see if this it what you were seeing...I think I shorted the DDM (Driver Door Module) to power (no harm to the module) and this is maybe what you saw !!...mine was a start and stall !!
Who in their right mind would design an electrical system like this? Probably someone on crack cocaine! Don't get me wrong, I enjoy my 04 C5 vert and so far no electrical issues. But after being on this forum for 5 years + and reading all the problems with the electrical problems with this car that I never, never, never, had with any of my vehicles this design format is just ridiculous. But that is what we have to live with with the GM dumbest designers in the C5. Sorry, just had to vent. My apologies.

Serial Data Bus issue are fairly common with ALL the Manufacturers not just GM !!...if not for this design your electrical system wiring would be 10 times as much as it is in the C5...it would be REAL nightmare !!...at least these splice packs (Star Connectors) were a great idea by the GM engineers...they NEVER intended it to be used for diagnostic purposes but I guess someone figured it out !!
exact same condition,same DTCs.
I thought it was odd that the RDCM on my car was not listing any codes
The RDCM was faulty and causing the condition for the old poster.
Will try unpluging the module and see what happens

Had a member with a Seat Control Module a while back who had a start and stall on his...he said he just unplugged it, inspected it and re connected...that fixed his !!...I would not only look at the PDM connector but the one inside that boot as well !!...yours may have just been an intermittent condition...if checking with a scan tool you will have ALL "NO COMMS" with all the modules if not intermittent plus the car won't start !!...none of the modules can talk to one another !!
