Check to see if it always comes on when you exceed a set speed.
or
Check to see if it always comes when you decelerate back down to a set speed.

Generally a fault that shows up after a certain amount of time running
will be a wheel speed sensor fault - something that the system must
test dynamically.

If the latter of the two checks above is true, then you might have a
wheel speed sensor that has backed out of its press-fit slot.  Push
then all back in as hard as you can and then see if you still get the
code.

also check for Brooklyn tumbleweed I guess , or any other thing that
might be interfering with the WSS:-D
