miev2012JP, welcome to the forum. Sorry to hear about your troubles.
Could you elaborate a bit more? Presumably the car is completely 'dead'? Do you have any indicators light up when you turn the key? 12v ok? The HV battery safety plug under the seat is in place? North American car (2012?), but you're located where? Perhaps a bit more detail might help us to help you, although very few of us have hands-on experience with that MUT-3.
