hello about 2 weeks ago i unplug my battery to fix the hose that goes to rear wiper it had come off and washer fluid was leaking from it problem solved. my next problem accuried a week later too my 07 equinox in for emission and state inspection. inspection pass emissions not ready. i was told since i unhooked my battery the obd has to read a drive cycle. was told to drive 75-100 miles then bring back in to have retested. 150 miles later took back same problem. go drive another 100 and bring it back. 100 miles later took back same problem. i got the story to keep driving some more. i own a innova diagnostic scan tool almost 700 miles later my scan tool is still showing that emissions is still not ready. no codes come up. so what is my next step what should i do.
