8B-36 Air Bag System:
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
All of the following conditions must exist for 5 seconds:
B0081 0F
• The SDM has received a fault present message from
the PPS.
• The PPS is in assembly plant mode and the SDM is in
production mode.
• After the PPS change states, the SDM signal stating
the Passenger Status Data Received is not valid
within 2.6 seconds.
B0081 3A
• The SDM has received an ID message from the PPS
which does not match the ID stored in the SDM
memory.
• The SDM has reset the PPS twice without detecting
the correct ID message.
B0081 39
• The SDM has received a NOK message from the
PPS.
• The SDM has not received a message.
B0081 71
The SDM has received invalid serial data from the PPS.
Action Taken When the DTC Sets
• The SDM commands the AIR BAG indicator ON via
serial data communications.
• The I/P module deployment loop will be disable.
Conditions for Clearing the DTC
• The condition responsible for setting the DTC no
longer exists and the scan tool Clear DTCs function is
used.
• A history DTC will clear once 255 malfunction-free
ignition cycles have occurred.
Diagnostic Aids
If either the SDM or PPS were replaced, verify that the
correct part numbers were used for the vehicle
application.

Circuit/System Testing
NOTE
When removing connectors, inspect for
damage or corrosion. Damage or corrosion
in the following requires repair or
replacement of the affected component/
connector:
• The PPS module
• The SDM module
• The PPS module harness connector
• The SDM wiring harness connector
1. Ignition ON, Verify the passenger air bag ON/OFF
indicators illuminate.
➢
If the indicators do not illuminate, refer to
“Passenger Presence System Indicator Circuit
Malfunction: ”.
2. Ignition ON, verify no PPS DTCs are set.
➢ If any PPS DTCs are set as current or history, refer
to “Diagnostic Trouble Code (DTC) List - Vehicle
Diagnostic Information: ”.
3. Verify the correct PPS part number is installed in the
vehicle.
➢
If the wrong PPS was installed, replace with the
correct PPS.
4. Ignition OFF, disconnect the harness connector at
the PPS module.
5. Remove the SDM connector. Refer to “Inflatable
Restraint Sensing and Diagnostic Module
Replacement”.
6. Test the occupant sensor serial data circuit for an
open/high resistance between the PPS module and
SDM connector.
➢
If an open/high resistance exists, make the
appropriate repair.
7. Ignition OFF, test for less then 1 ohm of resistance
between the PPS module circuit terminal D and
ground.
➢ If not the specified value, test the circuit for an
open/high resistance.
8. Ignition ON, verify a test lamp illuminates between
the PPS module circuit terminal A and ground.
➢
If the test lamp does not illuminate, test the circuit
for a short to ground or an open/high resistance. If
circuit tests normal replace the PPS module.
9. If all circuits test normal, and DTC B0081 is set as
current, replace the SDM.
Repair Instructions

Diagnostic Information: ” after completing the diagnostic
procedure.
