Traction Control light on with nothing else

What could be causing this light to be on and not flashing?

 

You may need to recalibrate your yaw sensor/controller...for my experience, my 4runner did this after a lift and it just needed calibrating...was a 5 min task...I'm not certain how it's done on a tundra tho...

 

That stinks. I wonder if it's related to having the battery unplugged for 2 days while I had my steering wheel off to install the leather wrapping.

I'd suggest it's due to the steering wheel being off...all good though as it us an easy fix...

 

Did the reset, but now the TRAC, ABS, and Brake light are all on.

 

Picked up an Autel scanner to best diagnose and service this truck w/o having to deal with hack-a-laptop for Techstream (also want to program keys in the future, as well). Got to troubleshooting the SAS, and couldn't get a reading on it whatsoever. Took out the ribbon cable/SAS module to see if it might be anything funky. Cleaned the contacts, checked the cables, no fuses blown anywhere under dash or hood. All seemed fine, and was about to order a new SAS module. Plugged it all back and ran the Autel again and it got a reading from the SAS.

*shrug*

Reset the YAW and SAS controller like linked above, all codes cleared. I have no idea what the hell happened, but I'll take it.

 

It could be as simple as a need to make sure your fuzes (under the hood) are fully seated, and facing the right direction (yes, it really does make a difference).
