Driving to work won't make all of the monitors get ready. 4 of the 7 monitors will get ready if you drive a cumulative total of 10 minutes at any speed and if you also stop the car 6 times from any speed greater than 25 mph. These 4 monitors must be run before the next two monitors will run.
You can make two more monitors (EVAP and Heated Oxygen Sensor) run without driving the car. When you get to work or return home (warm engine) let it idle in neutral or park with the ACC system either off or in ECON mode. Depress the accelerator for a second or two and then let the engine idle for 30 seconds. Repeat 3 times. These two monitors must be run before the final monitor can be made to run.
Making the catalytic monitor run is a pain. It won't run in ordinary driving. To make it run, drive normally for at least 5 minutes and check that the coolant temp is at least 140° F. Then drive with a steady throttle (no cruise control, ACC either off or in ECON mode, and ideally on a level road) for 4 minutes at a speed between 25 and 56 mph and rpms between 2000 and 3000. It is more important for the throttle to be steady than for the speed or rpms to be steady. It doesn't matter what gear you're in. If you're driving an automatic then this driving cycle is more easily satisfied in 2nd gear at about 34 mph (2500 rpm) or 3rd gear at about 47 mph (2500 rpm). In 4th gear you're too likely either to drop below 2000 rpm or go faster than 56 mph. You will need a stretch of road about 3 miles long that's ideally level and has no traffic. Good luck finding that.
The info above is taken from a Saab 9000 Service Manual 2:7 Engine Management System Trionic OBDII M1996-. I think it will work for any '96-'98 9000.
