You can't just unplug the OBDII port if you still have the harnesses connected. It will throw other codes when they start it up. Then they have even more reason to take a closer look. The harnesses are not passive; they are active and need the JB4 to work as a pass through.
Better to leave it on map 0 with the port still plugged in.
You should have completely removed it from the car. It takes like 15 minutes.
