Under DTC what do the numbers mean? Most codes have MIL on, MIL off and No error reported. Some have a number like 5,6 or 7. The drop down box has no numbers to choose from and if you change a 6 to a mil on, you can't choose to go back to 6. I have an 11 and 12 GT500 with different values for P0420 and P0430. One car has MIL On and the other has 6. The car with MIL sets the Monitors Quickly and the car with 6s takes forever. Any Input would be appreciated.
Thank You
