B0081 0F
The SDM sets this DTC if there is a fault present in the PPS module.
B0081 3A
The SDM sets this DTC when the SDM has received a message from the PPS which indicates a mismatch between the SDM and PPS module. There
is either an incorrect SDM or PPS module installed on this vehicle.
B0081 4B
The PPS module sets this DTC when the PPS module has not learned the calibrations.
B0081 5A
The PPS module sets this code when the PPS module has lost communications with the SDM.
B0081 39
The SDM sets this DTC when the SDM has received a critical fault message from the PPS module.
B0081 71
The SDM sets this DTC when the SDM has received invalid serial data from the PPS module.
Action Taken When the DTC Sets
* The SDM disables the passenger instrument cluster air bag.
* The PPS module will illuminate the Passenger Airbag On/Off indicator status as OFF.
* When the PPS module sets this DTC, the PPS module communicates with the SDM to turn the AIRBAG indicator on.
* When the SDM sets this DTC, the SDM will turn the AIRBAG indicator on.
* The SDM requests the instrument panel cluster (IPC) to illuminate the AIRBAG indicator.
Conditions for Clearing the DTC
* The condition for setting the DTC no longer exists and there is no activity on the low speed serial data circuits.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.
Diagnostic Aids
If either the SDM or PPS module were replaced, verify that the correct replacement part numbers were used for this vehicle.
