I'm a new owner of a 2012 TRD off road, with a V6 engine. Before buying this beautiful truck, I had my local mechanic check it out and make sure there no hidden codes in the computer. There were none. This truck has 124,000 miles and looks like the previous owner had taken care of it well. The other day, a very rainy day, I tried using 4H, ran great. I selected 2h before parking it in the garage, overnight. I drove it the next day, running local errands, no problems. The next morning, I get a check engine light, and a Trac off light. What the heck?
