Anti skid and Check engine light ON - 2010 yaris

[romram]

i saw this topic often, until it happen to my 2010 Yaris recently.
for some reason both slip indicator and check engine light ON. My yaris is about 185k miles. I tried to reset it by removing the negative side of the battery. it works for couple of weeks, then pop up again at the same time.
Googling it up, so many opinion online.
I am planning to bring it to toyota service center to get diagnosed (about $175 for an hour).
anyone (or most yaris user) have/had issues before?
please share your opinion / experience.
