Default MCU - Multiplex Control Unit, 01 Civic EX

I have an 01 Civic EX - same problem as other posts happened Today ironically, Dome light does not light while door is Open, Power locks don't respond to remote or door switch, A/C does not cool, and Brake light stays lit on dash.....

All forums/threads point to MCU under steering column,
