DTC B0098 : Passenger Presence System Configuration Error
Circuit/System Description
When the ignition is turned ON, the inflatable restraint sensing and diagnostic module (SDM) performs tests to diagnose critical malfunctions within itself. When the SDM has completed the power-up mode, the SDM will establish communication with the passenger
presence system (PPS). The PPS will respond by commanding both the PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds. The SDM will transmit a request message to the PPS to receive the PPS verification ID. The PPS will transmit the verification ID to
the SDM and the SDM will compare the ID received to data stored in memory. If the data stored in memory does not match the information transmitted by the PPS, the SDM will set DTC B0098 and command the AIR BAG indicator ON. The PPS will set DTC 064 and
request the SDM to disable the instrument panel (I/P) module deployment loop.
Conditions for Running the DTC
Ignition 1 voltage is within the normal operating voltage range.
Conditions for Setting the DTC
• | The PPS has a current fault. |
• | The PPS fault counter in the SDM has reached 127 counts. |
Action Taken When the DTC Sets
• | The SDM disables the I/P module deployment loop. |
• | The SDM commands the AIR BAG indicator ON via class 2 serial data. |
Conditions for Clearing the DTC
• | The condition responsible for setting the DTC no longer exists. |
• | The scan tool CLEAR DTC command has been issued. |
• | A history DTC will clear once 255 malfunction-free ignition cycles have occurred. |
Diagnostic Aids
Important: DTC B0098 will also set if the PPS has a current malfunction and has set DTC 064. The SDM will set DTC B0098 as current and command the AIR BAG indictor ON. This is done to notify the driver of any
PPS malfunctions. When DTC B0098 is present it is important to check the PPS for any current DTCs. Refer to
Passenger Presence System Flash Code Procedures
. If the PPS has any current DTCs, address these before
performing this DTC chart.
DTC B0098 is an indication that the SDM has received an incorrect PPS verification ID. The SDM will continue to request the verification ID from the PPS for 5 seconds. If the SDM does not receive the correct verification ID from the PPS within
5 seconds, the SDM will set DTC B0098 as current, illuminate the AIR BAG indicator, and disable the I/P module deployment loop. If either the SDM or PPS were replaced, make sure the correct part numbers were used for the vehicle application.

Circuit/System Testing
- Verify that the vehicle has the correct PPS and SDM installed.
⇒ | If an incorrect PPS or SDM has been installed, replace the incorrect component and perform the programming procedure for that component. |
- If the correct components are installed and DTC B0098 is set as a current DTC, replace the PPS.
⇒ | Replace the PPS and rezero the system. |
- If after replacement of the PPS, DTC B0098 is set as current, replace the SDM.
⇒ | Replace the SDM and perform the SDM Setup procedure. |
