It’s currently very cold where I live (-30 to -45 degrees Celsius) at nights and I went to start my car and it cranked a few times then died. I figured it was a dead battery so I tried to charge it and jump it but nothing and now it’s been sitting for a few days. When I click start all the lights come on and I can hear a little tick near my knees and the fuse box but not a single crank. I’m lost as to what’s wrong and can’t narrow down whether it’s the starter or not.

Edit: After scanning the car it gave one code: U110f
