At long last, with @PriusCamper helping, I got this figured out. It was the problem with corrosion on the 4-wire connector near the battery...
Thanks @SFO :) @PriusCamper helped me figure out my problem. No telling how much money he saved me. :)
Anyone in the greater Seattle area have a cable and Techstream software? I am getting some codes and would like to figure them out without going...
Yes I found the claim the cable broke things to be doubtful, but I'm paranoid. I don't have much spare cash and don't want to make things worse....
About 30% of the reviews for this product are one star. One guy says it shorted out his O2 sensors.... Makes me leery.....
Thanks, Dave. I really appreciate your answer. I'll check the brake system ECU. I have put the 12v battery on a charger. It is an optima yellow...

Anyone in the Seattle area willing to hook up and read codes from a 2005 Prius, or let me borrow your dongle/cable/sw? I have the red triangle,...
That's too bad as much as I paid for it. It's 3 1/2 years old, so just out of warranty. I'll just charge it up more. Thanks.
SOLVED I put the 12v battery on a 2A charge for a couple days. The lights have stayed off, and yesterday the red triangle went out too. In...
I've been putting the 12v battery on a charger, at 2A. The charger never shows it reaching full charge, but performance is better. I drove it this...
Thanks! I didn't know about this. I knew it would happen sometime. I'm driving the car in its current state. The lights will stay off (except...
Looking at this thread: 2007 Prius - Check Engine, Red Triangle, VSC Lights - 12 volt battery issue? | PriusChat I match that pretty closely....
@edthefox5 : Thanks for the info! I've also done just one discharge/recharge the past two times. That's what gets me above 50mpg. I use the...
