Cascadia ABS diagnostic switch location?

Hi guys

I am trying to locate the ABS diagnostic switch (AKA Blink Code Switch) on my 2014 Cascadia. My ABS light is on (807, fmi 8), and I am diagnosing it with a Wabco manual I downloaded, trying to see if it clears. My truck does not have that switch on the dash, but I read that sometimes Freightliner hides the switch somewhere weird, like next to the data port. There is a hole in the plastic next to the data port that kinda looks like it might go to a button, kinds like those reset holes on some electronic gadgets... could that be it? Pic enclosed...



Please let me know. My girlfriend is kind of a safety mama and she doesn't want to drive her shifts with that light on, but I don't want to waste time and money at Freightliner if it's just something I can reset.
