DTC ( See owners manual????) P1081 V70-XC70

I have now gone almost a week after disconecting the battery. I have not yet met readiness status on oxygen sensor or catalyst but also no CEL on yet either.
it seems to be taking a long time to complete the drive cycle?
I just checked for codes and found this P1081 see owners manual? What in the world does that mean? It did not produce any CEL but it is a present code.

Anyone know the exact conditions the catalyst and oxygen sensor tests are looking for? I am still hopeful to complete drive cycle with no check engine lights on. It seems to be taking a very long time to complete.
Please help if you can.
99 V70 with new rear O2

    Could be MAF sensor. Another issue: Is your gas cap tight?

      The MAF looked fine on th eVolvo System computer last week. Although it gave no answers either.
      The gas cap is tight, the see owners manual did not trigger any CEL it was only found when checking to see if the drive cycle had passed yet. Also the heating system flashes at start up so ther is a code in there. Maybe that could generate the see owners manual code?
      Thanks for the thoughts. still driving and still waiting for either a CEL or a ready status on the O2 and catalyst.

        Check your relays and fuses, but besides the fuses, the relays are hard to test. If the A/C system lights are flashing it could be a blower motor. Does the fan work?

          heating system works fine, I have heard that th etemp sensors get dirty and cause a code in the heating system,Guess I need the volvo tool to get the code?
          I have just found some generic drive cycle instructions to complete the O2 and catalyst. I will try it this morning and see if it applys to the Volvo. instructions found in my Genysis scan tool. Thanks for the thoughts.
