Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.
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

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
