Tire pressure sensors

[Power6]

Note, I may have already said....don't freak out at the flashing TPMS "warning light" icon. It will be that way until learning is completed, then a message pops up on the IHU or DIM, saying "TPMS calibration complete" or something like that, then you are good!

exactly how long does one need to wait for the vehicle to figure out the sensors and perform a successful "calibration"?  (I did a couple errands about 10 miles apiece.. total driving time around 30mins).

So everything you have looks good, those are the right settings. I get the feeling...something is wrong before you even set off. When I tapped "calibrate" with new sensors, the spinny circle just stays there, no errors, then I went for a drive. 

Have you checked codes, got any? We'd want to see if any related DTC is set and that may give you a clue. You should not need to do anything, sensors don't need to be activated, and they don't need to be learned, the car does all that automagically. You can check the TPMS IDs in OrBit "Service Tab", and even edit them, I just wouldn't do that yet, as we can watch the sensor ID fields as a way to see if the system is working, if those sensors IDs do get updated properly by the car. By default they should be all 0's to start. 

I don't know what conditions you need to get through and how long, to calibrate. I think it was about 15 min driving for me. Volvo has info in various owner's sites/manuals about recalibrating, but not on the process of learning new sensors and how long that takes.

Just to check...the car has keyless operation right? Proximity key whatever we call it, keep the fob in your pocket, touch the door handle. Probably should have asked but I was pretty sure all the US S60s are going to have that, I could be wrong. That is going to be required for "auto-learning" to work for TPMS. If you don't have that, I do beleive TPMS will still work, but getting the sensors learned will need to be done manually, added via OrBit, and I think you will use a different config setting. Nobody has tried it yet to confirm but we could work through it.
