JSCAN: changing tire size mess up, auto braking

[56cbr600rr]

Using the Jscan earlier, we changed the tire size from 33.03 to 34.75 For 35’s. Now the auto collision braking light is on. Coworkers 2020 Rubicon JT Auto.

NORMAL? WHAT IS THE FIX? CAN WE CHANGE THE TIRES BACK TO 33 TO eliminate THE LIGHT?

sorry for caps…

Sensors for the Safety Group package may need to be calibrated but I really do not see why as I am sure your friend is not the first to adjust the tire size and have the Safety Group package.

Not normal. I have a 2020 sport with the safety group. What is the code being reported?

Fixed. Cleared codes. Went back to 33, went back to 34.75 and all good.
