Service advance trac light

[Austin2013SHO]

Hey guys anyone have the service advance trac light come on and off randomly? Mine is random with zero DTC’s and traction control still works and can be turned off and on aside from the service advance trac light. I’m assuming it’s a wheel speed sensor but before I got buying parts want to be for sure. Any advice is appreciated.

Mine did the same, esp after a hard quarter mile pass. Never gave it much thought. I just turned the car off, and then back on and went about my way.

There should be a DTC stored in the ABS or another module. An OBD2 code reader will not read that.

My car periodically does this and the stored code in the ABS module is always "missing calibration for the steering angle sensor".

I had the same problem on my 2015. It ended up being the steering rack.

Ok I have a snap on modis I will check to see if it has anything stored but mine will come on randomly and any time u turn car off it goes away until the next time. So if I don’t see anything I will go around the block until it comes back on and then scan it with the modis to see what it says but I’m willing to bet it’s a steering angle position sensor going out or a wheel speed sensor. I’ll keep yall posted.
