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 of the PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds. The SDM will then 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.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
The SDM has received an incorrect PPS verification ID.
Action Taken When the DTC Sets
• | The SDM will disable the instrument panel (I/P) module deployment loop. |
• | The SDM commands the AIR BAG indicator ON via serial data communication. |
• | The PPS will turn ON the PASSENGER AIR BAG OFF indicator. |
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
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. If either the SDM or PPS were replaced verify that the correct part numbers were used for the vehicle application.

Circuit/System Testing
Important: 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 wiring harness connector |
• | The SDM wiring harness connector |
- Check to see if the PPS was replaced. Verify the correct PPS was installed.
⇒ | If the wrong PPS was installed, replace with the correct PPS. |
- Check to see if the SDM was replaced. Verify the correct SDM was installed.
⇒ | If the wrong SDM was installed, replace with the correct SDM. |
- Check to see if DTC B1001 is set. Verify DTC B1001 is not set.
⇒ | If the connector for the PPS is damaged, the PPS must be replaced. |
- Replace the PPS. Ignition ON, use the scan tool to clear the DTCs then recheck for DTC B0098. Verify DTC B0098 does not set.
⇒ | If DTC B0098 resets then replace the SDM. |
