All,
My 2000 all of a sudden started with warnings on the dash. The obvious =
"Service Engine Soon" but also "Reduce Engine..." then "Check Tire =
Pressure" and "Low Fuel." The thing is that tire pressure is about 30 =
(which is lower than what I would like), the tank is more than half full =
of gas (the fuel gauge all of sudden marked empty). Another symptom is =
that the windows and doorlocks froze, and do not work.
Overnight, the lights on the radio plus others stayed on, and now the =
batter is dead.
Any suggestions on early diagnosis - the ECM or a relay?

WAG: BCM issue. Ground, loose connector etc.
I believe the C5s had different control modules layouts for engine
(ECM), body (BCM) & security (donno). Same code for two different years
might be coming from different modules. IIRC, both tire pressure and
door locks were in the security model in the early C5s. Later that got
combined in the BCM. More recently, it's a Power Train Module and Body
Control Module--with data shared across a network intertie.
If the old ploy of disconnecting the batt, fully charging it and then
reconnecting it didn't work, try a post in the C5 Scan and Tune forum.

I've had all the codes dumped from my '02 by a Dyno-tune shop-- *much*
cheaper (and quicker) than visiting a dealer -- if you can get the car
there. Other advantage is that you get to talk to the guy who dumped
the codes, not just a lame translation from a service adviser.
Best of luck and Happy Turkey Day.

Pi, Tom, etc,
Thanks for your input. I decided to simply buy a new battery. Same =
problem after about 20 minutes of test driving.
The thing I noticed is that even after not having a battery for about =
30 minutes, the car still remembered the radio settings.
I suspect what Pi mentioned concerning the security module that also =
ties the tires and doors. In the past, I had noted the "security" light =
come on while the car was being driven, no this.
Is there a reset procedure or process?

Really, if there's any deductible or cost sharing on that warranty,
suggest calling around. Find a dynotune shop that can scan all the
modules for all codes. Answers might keep the dealer honest.

Re: Strange behavior on 2000
without your own scanner etc., it may be little hard.
you may have already done the basics....
but have you checked as many grounds on the car for
loose connections
checked as many electrical plugs/connectors for loose
fittings?
reset your ecm module somehow....
i know on some cars it wont work if you just pull the battery
cable off, but instead you need to pull the main fuse for the
ecm for 10-20 seconds etc. for it to reset.
that's what some techies will do before they bother to check
so they get a clear picture when plugging in.
is it heat related?
after you've driven it for the 25min and start seeing the codes
pop up, pull over and let the car cool down well.
what happens when you start her up again?
do the codes clear or are they still there?
my 2 cents

Re: Strange behavior on 2000
Thanks Harry, no I do not think it is heat related. As soon as the
signal/warnings come up, I can pull over, turn the car off, restart, and
like nothing ever happened. I have been checking ground and loose
connections from an open hood (but nothing underneath the car yet though -
will get to this weekend). I did not think about pulling the main fuse to
reset the ECM, good idea.

Problem fixed. After changing batteries, replacing fuses, and =

I have a 2000 C5 with similar problems all dash flashing/ service
engine, Losing power, all gauges go off, dash lights up like a slot
machine...I think its a short in the passenger door harness from
opening and closing door, as window doesn't work unless I shake wires
in between door and car hinge..., then passenger window works.. I need
to fix it, procrastination!!

Hey Cas,
You are right on track. On mine, it turned out to be a door module that was
causing all the problems, and the tech had also found a short in the wiring.
