    I have this 2015 Tundra and it sat for a month or so and wasn't run much over the winter here in PA. Once I started it, the check engine, traction control and 4L & 4H were flashing. It runs fine, except you cannot shift into 4 wheel. I reset the ECU, checked fuses and found nothing. Any ideas what my problem might be? Bought this as a second owner, never had any issues with it for well over a year and has only 42,000 miles on it.

    Ii was out of town and finally got to take a good look at my Tundra. Yes, it does sit outside and I have had issues with critters before. Today I had it up on ramps and really looked. I did find a wire off at a plug that goes into the module near the gas tank. It was the red wire. I cannot determine if it was critters or not so I posted a picture. But the story is interesting. After repairing, the flashing 4L & 4H lights went off but I still had the check engine and traction control. I reset the ECU again, no help. I decided to drive it some and see if that makes any difference. Yes, the traction control went off and now I only have the check engine light. Everything is working as it should. I am in the process of doing a battery disconnect reset right now and see if that makes a difference. I'll be away for a few days but will report back on my findings and the inevitable solution. Thanks to all.

    Do you always top of your tank when filling up? If so....you shouldn't. Can cause evap system issues.
