2006 Prius just randomly won't start

Same thing happened to me, no solution yet. I had damage to my front drivers door and I replaced it from a junked car. I got the beeping you described. By depressing the switch in the door frame which tells the system the door is closed the beeping stopped.. It worked with my finger so I clamped it. the door is open, but the clamp has stopped the beeping. The lights in th cabin looked dim to me so I turned them off. I wonder if I have replaced the door at the same the starting 12 v battery has gone out. Mabey disconnecting the door's power connectors and replacing them is the cause. Any ideas?

 

try disconnecting the 12v neg cable for 15 seconds, it resets the computers.

 

if you're on the original 12v, you should replace it whether it's bad or not. save yourself a headache in the future.

 

Yep.

Please run the test at Weird stuff happening? MPGs dropping? Test The Battery | PriusChat after the car has sat MANY hours or overnight. Please tell us the 3 values (not just 1). Don't go changing the battery first until you tell us the values...

If you have HIDs, you can avoid unnecessary cycles on the lights by toggling between off and parking light positions.

Weird stuff can start happening w/a low or bad 12 volt. Don't waste $ on having a dealer "test" the 12 volt (07 Prius Dead - Any Guesses? | PriusChat). If you're on you're original 12 volt, it's VERY likely near or at end of life now.

 

mark, you're getting a workout lately!
