you may still have warrenty left and should have it inspected by a qualified Technician but here is what I found that may be of some insight...

#07-09-41-002: Air Bag Light On, DTC B0081 Set (Clear
DTC Using Specific Procedure) - (Jan 29, 2007)
Some customers may comment on the airbag light being illuminated. Upon investigation, the
technician may find DTC B0081 with symptom code 0F, 3A, 39 or 71 set.
The Sensing and Diagnostic Module (SDM) should NOT be replaced when DTC B0081 sets. The SDM
sets DTC B0081 only to report that there is no communication with the Passenger Presence System
(PPS) module or that the PPS module has reported a fault. It is important that when the B0081
fault is reported by the SDM, the DTCs from the PPS be retrieved and addressed first per the
procedure below. After the PPS module DTCs have been addressed, turn the ignition off, open the
driver's door, and wait 40 seconds for the PPS module to go to sleep.
1. When DTC B0081 71 sets, inspect wiring and connections for a possible loss of
communication between the SDM and PPS module. Inspect front passenger seat connector to
the PPS module and seat connector to the seat harness. Do not replace the SDM module for a
DTC B0081 71 condition.
2. The SDM will set B0081 3A indicating that a wrong PPS module has been installed on the
vehicle. Verify the condition before replacing the known wrong PPS module with a correct
one. Use service information to reprogram and set up a new PPS module.
3. The SDM will set B0081 0F and B0081 39 indicating that the PPS module has reported a fault
to the SDM. Retrieve the DTCs from the PPS module and address those first.
4. The PPS may continue to send it has a fault to the SDM for the above conditions, though
there are no active faults reported by the PPS, until the steps in the note below are taken.
Important: DTC B0081 will not clear until the low speed bus goes to sleep. To clear DTC B0081,
turn the Ignition off, open the driver's door and wait 40 seconds for the PPS to go to sleep. Turn
the ignition to run and retrieve vehicle DTCs. If all the codes have been cleared from the PPS, DTC
B0081 in the SDM will not be active and only be in history.
