My 2012 Optima SX (95K miles) won't start. It only goes to ACC mode, it's got a brand new battery, and the override trick for the brake lamp issue doesn't work either. The code we get is P1690 for SMARTRA. Has anyone had experience with this code? I'm really hoping I don't have to get my car towed 30 miles to the dealership.
