Started my 2012 Platinum and headed down the street. Noticed my Traction Control Light on. My Check Engine light on, and my 4Lo indicator was flashing. Long story short, couldn't find anything that didn't work. Read this forum and no one had the same symptoms. Finally took my truck to Auto Zone and had them hook it to a diagnostics. That came up with an Air Fuel Mixture board was bad. Popped the hood and found a wire to my AFM board was broken. Waiting on the delivery of a new wire harness. $11 bucks.
