Default Accessport Block OBDII scanners?

I only ask this as I just went in for emissions in Wa and they were unable to connect to my ecu through the OBDII port. My accessport still connects no problem, before and after the tests. Was this a testing facility issue or does Cobb have a block on these scanners? If it is an accessport feature, does the accessport require being un-married before my next round of emissions? Luckily I was able to pass the sniffer, even being catless!

I had this issue once and it turned out the last time I used the AP before the test i must have loosened the OBD port from where it sits. The guy just couldn't get a connection so he told me to have it looked at and come back. I pulled into a parking lot to take a look and the thing just wasn't there. If that's not the case than I have no other ideas. The AP shouldn't cause any issues as far as being able to read data from there.

You should not have an issue connecting to the ECU with an OBDII scanner with the AccessPORT installed. It should connect as it normally would as we do not lock out any scanner, code reader or other equipment, you just can't write to the ECU with the AccessPORT installed. Try reading the ECU with a generic OBDII reader and see what happens, however, this should work normally!
