2007 Prius not shutting down. It did it once before and mechanic disconnected something (I believe he said a fuse) and reconnected and it worked for about a month but did it again. What has gone bad?

Hey how are you

1-ask the mechanic what fuse did he pull out and let me know ?

2- you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the car modules so we can narrow it down

3-For now lets try A Master reset to see if that will reset it

Master reset Procedure

1- Disconect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You

I asked mechanic and he said he actually just reset computer (not sure if that entails the steps you recommended above).
Expert:  Chad Farhat replied 3 months ago.

yes this procedure that will reset the computer also, just like using a scanner to clear , we talking about the 12 volt battery in rear trunk here .

if no scanner is available ,u can manual reset that weay

but a Toyota scanner is needed so we know why , did he scan it then & retrieve any fault codes

Please let me know

Thank You
