I STARTED MY CAR AND THE AWC SERVICE LIGHT CAME ON. IT WAS ABOUT 0 DEGREES OUT THAT DAY, WHICH IS A VERY UNUSUAL TEMPERATURE FOR S. INDIANA. WHEN I STARTED THE CAR IT SCREECHED FOR JUST A SECOND AND THEN POPPED UP THE CODE. I RESTARTED THE CAR, JUST AS THE MANUAL HAD SAID AND WHEN I RESTARTED IT THE LIGHT WAS STILL ON. I WAS ABLE TO GET THE CODE READ IT THREW A C161E CODE WHICH IS AN ACD/AYC PROBLEM. AFTER DOING A LOT OF RESEARCH I FOUND OUT ITS A COMMON PROBLEM AND ITS AN EXPENSIVE PROBLEM, ABOUT $2,000+. I CALLED THE DEALER AND WAS TOLD MY WARRANTY DOES NOT COVER THIS, IT IS NOT PART OF THE POWER TRAIN. *TR
