Then I agree with tankyoung, it is probably your 12v aux battery.

Have you tried disconnecting the 12v battery and let it sit for about a minute, then reconnect it?

I had a similar problem with my 2008 Prius

try testing it first. is it original?

 

You'll have to take it to an auto parts store like Pep Boys or Auto Zone

I'm going to guess its a bad combination meter. If the10amp fuse is blown, the display would've gone out. the ECU controls the combination meter, and that rarely goes bad. I would bring it to the dealer and have them diagnose it if no one can guess what it is on here. Hopefully it's still under warranty, or if there is a TSB for this issue.

here's the attached file (thanks to Mendel ), hopefully this helps.

 

It's the one where the blue wire comes out from. It doesn't say on the file but check under the driver kick panel.

 

Check all the 10amps, on the cover, it will display what each fuse is for. If none of the fuse are burnt, it's the display then...

 

I have 2010 prius and the same problem as you mentioned above with the speeedometer, would you mind if I ask how you fixed it?

 

have you checked the 12v and fuse?

 

I put the new 12v battery one month ago but I don't know which fuse is related to!
I checked the fuse box inside the hood and there were be ok.

 

i don't either. i think there is also a fuse box by the drivers left foot? maybe something came loose behind the display, or, it could be defective.

 

Thanks,I will check them.

 

Test it. Much better than relying on an internet opinion poll.

Either do it yourself, at the least a rudimentary check of voltage with a multi meter, or more comprehensive assessment with something like Solar BA5. Or check with battery retailers: they should have pro-level electronic battery testers, can determin it's voltage, Cold Cranking Amps, and a verdict. Dealership can do similar test, but will charge $75+ I think.
