So I recently disconnected my battery on both terminals to do some engine work. When I reconnected everything, I completely lost all electronic controls. All door locking functions, rear hatch window, and the AC

The only functions that still work are my power windows front and back, and the door locking but ONLY when the key is turned

I have done this countless times before and never had an issue. I tried resetting the ECU multiple times to no avail. The only thing I can think of that I did wrong was reconnecting the battery terminals negative first. (I guess there is a proper way?)

PLEASE help me if you have an idea. I guess my next option is taking it to Toyota but I don’t want them to rape me for a service that could very well be simple. Has anyone run into any of this. 06 and everything is electronic these days

Check all the fuses to start.
