Tire monitor system light came on

This code is a Traction Control disabled code, my guess, go with the obvious. They may have put on a tire size that the ECM for ABS and Traction control does not recognize. The ride Height of the vehicle may not be correct or another symptom its seeing. The tire size and pressure is on a tag on the inside of the driver side door

A reset is possible, but are you sure you have the right tire size on for the vehicle, another possibility is one of the ABS sensors or wires have been damaged during the tire change over. You can do a visual inspection of the ABS sensors and their wires and just see if u notice any damage. Something has changed to set that code. You may just try clearing the code and see if it comes back.

I have been doing a lot of reading about this code, its a lacking communication or fault in another module to the EBCM. I would just erase it for now go for a good road test and see what comes back for codes if any.
