Traction light issue

Hi,
I noticed today when I started my truck the traction off light came on and went off as usual but traction indicator light comes on and stays on. No other lights come on. Pushing the traction switch on the dash does nothing. Turning the key to the on position then holding the switch for 3 seconds does not reset anything. Pulling the battery cable for 20 minutes didn't do anything. Intentionally spinning the tires in gravel didn't do anything. The only thing I've down was add air to my rear tire because it was low. No blown fuses. I took the truck to Autozone but they told me all their scanner would do is analyze check engine light issues. Any guesses?

 

Try Oreilly's.. they have their high dollar OBD reader and got me a full list of issues before I invested in a bluedriver, then a veepeak for additional transmission temp diagnoatics

Not sure if this will help in your situation, but the chart in this post can be used to troubleshoot the flashing lights when it comes to 4H/4L and Traction control.

 

Thanks for the thought. I took the Oreillys route. I did a couple of checks and have no 4x4 either. O'Reilly's scan only showed 1 fault code. U0114 lost communication with 4x4 clutch control module. When I looked up U0114 it's just says battery. Battery is fine. I have an appointment with Toyota

 

I'd almost be willing to bet it is a wheel speed sensor, but thats just spitballing. When I was dealing w a dash full of flashing lights, I bought a bi-directional scanner and it isolated the specific wheel speed sensor that needed replaced.....wasnt the one I thought it was going to be.
