Hi its a 2lt turbo wrx with a g4 plug in. I took it for a stomp today i did have antilag on and as i was nearing home i noticed check light was on and . The fault code list said something about the voltage at the an v9 pin has been above the error high voltage for more than one second. Basiclly i need someone to dumb it down so i can understand what its mean and what i need to do.

Thanks trent

P.s. antilag was working correctly. And launch control is on the same switch as antilag but wasnt used
