Never heard of a "V" code.....
Which also makes sense when you figure in C1276 and C1278, which both seem to be related to the traction control system.
My guess is that the issue is electrical, and it took the EBCM offline when it happened. I would start by checking wiring and fuses myself. Also grounds, and battery connections would be the next place if a fuse isn't blown. When cleaning battery connections, it will also allow everything to reset because the battery will be disconnected for a period of time.
If the issue still remains after that, then it sounds like some deeper troubleshooting is in order.
