Could there be something that's causing the battery to put out high voltage, or is that what the battery rating is?
Please read Posts #12 and #18 again.

If you're sitting in the driveway, doors open engine off, key: ON playing with stuff and pulling codes the battery voltage will drop RAPIDLY - and the fuel door and trunk WILL pop open. Low battery voltage.

So then it's normal under those circumstances?

It's not that common. Battery voltage has to get pretty low (damn near dead) for that to happen. I've never tried it, but I'd bet you could leave the key on and run the radio for an hour before you drain the battery low enough to start popping open fuel doors.

Well that's what's confusing: everything runs fine with it electronically, except the alarm, which hasn't worked properly since it came out of the shop. Other than that, it starts up fine, and all of the accessories work. I also don't leave anything on without the car being on...a lesson I learned by burning out a battery in another car back when I was traveling for work and using my car as an office. I don't have that problem with this car now.

This only happened when I was pulling codes, and I don't even remember how I did it, though I did it twice with the same process.

Hmm, factory alarm or aftermarket?
What was it in the shop for? There may be a clue there.

GM,
So far I am not getting any codes whatsoever regarding the sporadic light in question, but can you tell me where these sensors are located, front/back, left/right? And if I were to go ahead and replace one, which is more likely to be the culprit? I'm thinking the left front.

Cheers,
Serge
