Did it stall on you or just wouldn't start oneday? If you erase the P0685 is it the only one that returns?
Customer: replied 1 year ago.

Here is the diagnostics for the P0685. Can you run thru them and tell me what you find? It's possibly a bad TIPM.. Have you tried a hard reset by disconnecting the battery for 5 min and see what happens?
Customer: replied 1 year ago.
