04 Avalon computer gone crazy - Toyota Nation Forum : Toyota Car and Truck Forums

After removing and cleaning my battery cable clamps and posts, I couldn't start the car....clicking, etc. Also, the wipers come on while trying to start and the wipers are OFF. The CD changer started trying to change. I hit the Sound system On/Off button to turn off and the Horn honked! What's happening??? I knew I'd have to reset the Time and Date, but how do I reset the computer??? Help!!!

make sure you put the correct cables back onto the correct battery posts. I had something similar happen to me in my honda. i had the ground on the +12v battery post. didn't damage anything

OK, I found that the battery was only putting out 10 volts even though the green indicator was on. Installed a new battery and everything works now. I'm still surprised how so many crazy things were happening with one dead battery cell. Go figure!!!

I have one friend who owns his own repair shop and another who owns his own tire and brake store, and both say don't ever trust the green indicator on a battery. Depending on the circumstances either have the battery tested or replace it. Just a little FYI....
