Have Toyota Questions? Ask a Mechanic for Answers ASAP
Thanks for posting, have you checked the fuses under the hood in the box near the left headlight, do you have a voltmeter?
Open the red plastic cap , do you have more than 12 volts there at that point?
Let me see if I can get my wiring diagram and get back to you.
Check the 100 A DC/DC fuse, does it have power to it and is it intact?
Ok then there is the problem, the main fuse before this one is blown, I'm going to look at the fuse box diagram and see where it gets power from, be right back
The rectangular long fuse is an integrated fuse assembly which has many fuses built in, it gets power from the 120A main fuse which is on a fuse block mounted on the positive battery terminal so let's go there first and work up from there, does tis fuse have power on both sides (in and out) or is it blown?
Ok, it has power to it but probably an open circuit, let me check to confirm this.
You have power coming to the integrated fuse but some segments in it seem to be blown out, the solution is to replace this integrated fuse, you should be able to see one bolt/nut where a heavy cable is attached, there is another one at the other end that is a little harder to remove, you may have to disconnect some connectors and partially take the fuse box assembly apart.
It usually happens if by some mistake even for a split second the battery charger or jumper is grounded or reversed
Copy that link into your browser there is some good information there how to replace it, if it doesn't work let me know.
Just highlight it and paste it into your search or address bar
From what you have told me that you have power to the fuse (under the red cover) and the other and some of the other smaller fuses being dead, there is no other logical explanation other than there are some segments in the fuse assembly that are burned out.

What error message did you get?
If there's a problem with the main battery, the vehicle will not go in to READY mode and will give you a message.
If there's a problem with the small battery, by pressing the button there wouldn't any lights coming on.
A blown fuse will shut down a whole system or/and partial of other systems.
For example, if you have a blown fuse your power windows may not work but all the rest does.
Regarding the lights still being on. Unfortunately, just with the code reader and because it's a Hybrid the code reader should be able to read 7 code digits.
I'm afraid that's the information that I can think of.
Yes, of course. Hope to hear from you soon.
