Electrical problems - Mirror, MFD, Clock, Radio Dead

I've trolled as many threads as I can and haven't found an exact match to my problem. My 2006 Prius had a severed ABS sensor cable from me kicking snow/ice out of the rear left wheel well. I then has the ((!)) VSC and ABS and E brake lights go on. Then, my radio quit, then the clock, nav, interior lights and finally the entire MFD. It wasn't an obvious fuse as I checked them with an ohmmeter and even replaced the ACC and Dome even though they checked out ok. Disconnected the negative terminal for a reset and nothing changed. Checked the battery output with a multimeter and it was fine. Finally, brought it to the dealer and they found the bad cable and bad steering angle sensor. Now, the warning lights are gone, dome lights work but the mirrors, clock, MFD and the lights for the Park and Power button are out. Could this be a cold soaked IG1 relay? The headlights are fine and the car starts on the first push of the button. I don't want to spend more at the dealer for diagnostics if I can help it.
