Slow day here.. Took a while for the house to get moving today… Not much to report.. my mom is here.. which is nice.

My one accomplishment for the day was to turn off the back up beep in our prius. It used to be as simple as flicking the odometer button back in forth in a certain sequence to signal the car to turn the beep off.. btut sometime around 2010 they turn off that simple work around. Now it requires an OBD interface and some white knuckles programming..

I found some info online.. then jacked into the car.. and here is the conversation we had (my typing is at the >’s

Believe it or not.. that did it !>.. the car now makes one small plasant beep when you with into reverse.. rather than the ear splitting 'beep-beep-beep ----' 
 the funny thing is.. at no point in the exchange did it ask me who i was or whether I had permission to make such a change..

now that's interesting !
