How do I turn the back up beep off? I Googled it and found several walkthroughs that were all the turn it off turn it on ODO put in reverse ect ect, and I tried it several times and it's not working for me. Is there another way to do it or is it perhaps different for the 2010? Thanks for answers
There are 2 ways that I'm aware of: you can ask the dealer to do it for you, or you can buy an ODB-II tool and do it yourself. I don't have an ODB-II tool myself (yet) so I can't help you with the details.
The Gen 2 Prius, which you do not have, could be turned off via the instrument panel, as you found. The Gen 3 Prius, which you have, can only be turned off via OBDII commands, the dealer has a ODBII programmer called Techstream. Some owners buy ODBII programmers as well, I own a Scangauge II but there are others. On-board diagnostics - Wikipedia, the free encyclopedia PriusChat Shop : ScanGauge II Scan Tool + Digital Gauges + Trip Computers [ScanGaugeII] - $159.95 There are a LOT of threads on this topic, just remember you want Gen 3 threads. Those for other cars will just confuse you.
Only the dealer can do it.......or as noted above if you own or know someone who owns a OBDII whatever.
