1100 problems

Was out riding last weekend an during a pull wrench come on and sled dropped 2000 RPM got it to the botttom of the hill and found coolant coming from the over flow hose. let cool down then took another run at the hill went up and over no problem so I desided to take another run and got the wrench code again and again coolant from the over flow hose.
Dealer pulled 3 codes.
P 0326 boost pressure control at regular fuel judgement
P 0780 gear position error
P 2502 Low volt battery

Any ideas
