All idiot lights on

Simply disconnecting the 12v battery in the back for a few minutes will reset it temporarily. Does not mean the problem won't immediately or won't soon come back. If you or your insurance paid for a repair, you should take it back. There are other scanners that will pick up codes. You are about 90% likely to need more repairs.

 

It is the case, and body shops are supposed to have it, or make arrangements with a shop that does: see Toyota’s Collision Repair Information Bulletin 2016-191, “Scanning for Electrical System Faults.”

Once you have a Toyota Techstream diagnostic system—that is, a PC with Microsoft Windows, a vehicle interface module and its software, and the Techstream software from Toyota—then you’d use its Health Check feature to retrieve the diagnostic trouble codes (DTCs) stored in the car’s computers.

Every DTC is described in the Repair Manual (more info), which provides step-by-step troubleshooting procedures. Even if you don’t attempt any troubleshooting or repair yourself, knowing what’s wrong and the range of possible causes could help you make an informed decision about how to proceed.

Because of the way the car’s computers are interconnected, many different problems will cause several warning lights to come on at once. Until we know what DTCs have been stored, it’s impossible to say whether your issue is the same as anyone else’s, or how to correct it.
