Code P0A63, C1311 and C1313

Can anyone help me with the following codes. It's a second generation 2006 model with 180000kms. I was getting P0A63,P0A7A and P0A78 but after replacing the 12v battery P0A78 and P0A7A is gone. But still it's giving the same problems. Red triangle,engine,yellow warning and vsc is on. Troangle and engine is on when I start but th moment I put into gears the vsc and and yellow warning comes on and engine makes a loud noise and car shudders and Hv battery cuts off so no real power in the car. C1311 AND C1313 is from Abs/VSC and I see two abs relays are blown
