Yes I have the proceedure, only thing I suggest is pray for forgivness from the Volvo Gods. It took me two weeks to get the stupid things set 2 years ago.
I bought my code reader from this guy

it is a must so you can see exactly what your car is doing and get the timing down with a stop watch. Really it is a two or three person job. One to drive one to run the stop watch and read the directions(step by step) and one to watch the engine speed and call out RPMs in real time mode.
Oh yeah if you get stightly off on any test element kiss that cycle over, it is insane how critical a stupid ECU can be. last thing don't shut your car off after last drive cycle.
I talked to a local Volvo tech they want $500 now to do the proceedure for you.
On a dyno in an AC controlled building.
I got the proceedure on Dec 5, 2002 on this forum thread ID 556151
I used this page and it was the one that actually passed the test and set the codes.

OBD II Readiness Codes: Revised Reset Instructions
Background
The MY 1996, 1997 and 1998 Volvo 850/S70/V70/C70s require an extended driving period in order to reset readiness codes from INCOMPLETE to COMPLETE. When verifying an emission related repair, the TRIP identified in Section KKKK of the Engine Management System Service Manual TP 2308202 M 4.4 or Section EBU of the Engine Management System Service Manual TP 2301202 M 4.3 may not allow all of the diagnostic monitors to run.
The following instructions, which supersede TRIP instructions contained in the above referenced service manual, will exercise all of the diagnostic monitors on these models. As long as no diagnostic trouble codes have been stored, the readiness codes will be set to COMPLETE upon completion of two consecutive trips driven according to the instructions.
Introduction 1
This on-road driving sequence will allow all of the diagnostic functions an opportunity to run. After two correct, consecutive TRIPS, the readiness codes should be set to COMPLETE, provided no diagnostic trouble codes have been stored.
General Instructions 2
Engine temperature at start must be below +50°C (122°F).
Air conditioning (A/C) must be off during idle periods. A/C compressor activation during the Evap diagnostic may interrupt the Evap test.
Select a suitable route where it is possible to safely stop at the side of the road. Obey all traffic regulations and posted speed limits.
