I am not even sure your car has one!, does it have a red tag in the key ?
All I know is the pats module was under the dash bit on the mondy right up front under the ash tray area.
It might pay to phone FOCUS & MONDEO PART, 01603 866999, as they will know where it is.
Is your car starting ok and all that, is the pats light behaving ?
