I've not confirmed that SS and PPV systems work exactly the same, but here's something (3 consecutive posts - via above link) that may shed some light on TPMS function and how it can be adjusted.
And there's this, from SS owner's manual: (beginning on page 10-45)
TPMS Sensor Matching Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light and the DIC
message, if equipped, should go off
at the next ignition cycle. The
sensors are matched to the tire/
wheel positions,
using a TPMS
relearn tool, in the following order:
left front tire, right front tire, right
rear tire, and left rear tire.
See your
dealer for service or to purchase a
relearn tool.
There are two minutes to match the
first tire/wheel position, and
five minutes overall to match all four
tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select
the Vehicle Information Menu in
the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to
the Tire Pressure Menu Item
screen.
5. Press and hold the SET/CLR
button to begin the sensor
matching process.
A message requesting
acceptance of the process may
display.
6. If requested, press the SET/CLR
button again to confirm the
selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARN or TIRE
LEARNING ACTIVE message
displays on the DIC screen.
7. Start with the left front tire.
8. Place the relearn tool against
the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.
9. Proceed to the right front tire,
and repeat the procedure in
Step 8.
10. Proceed to the right rear tire,
and repeat the procedure in
Step 8.
11. Proceed to the left rear tire,
and repeat the procedure in
Step 8. The horn sounds two
times to indicate the sensor
identification code has been
matched to the left rear tire,
and the TPMS sensor matching
process is no longer active.
The TIRE LEARN or TIRE
LEARNING ACTIVE message
on the DIC display screen
goes off.
12. Turn the ignition to LOCK/OFF.
13. Set all four tires to the
recommended air pressure
level as indicated on the Tire
and Loading Information label.
