Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Initial Inspection and Diagnostic Overview) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Initial Inspection and Diagnostic Overview) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Initial Inspection and Diagnostic Overview)provides an overview of each diagnostic category.

DTC Descriptor
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 or B0092 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 PPS verification ID does not match the ID that is stored in the SDM.
* The SDM has loss or no communication with the PPS.

Action Taken When the DTC Sets

* The SDM will disable the 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 and/or DTC 064 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. If either the SDM or PPS were replaced, verify that the correct part numbers were used for the vehicle application.

Circuit/System Testing

1. Verify the correct PPS is installed.

• If the wrong PPS is installed, replace with the correct PPS.

2. Verify the correct SDM is installed.

• If the wrong SDM is installed, replace with the correct SDM.

3. Verify DTC B1001 is not set.

• If DTC B1001 is set go to DTC B1001 (B1001).

4. Replace the PPS.
5. Clear DTCs, and verify DTC B0098 does not set

• If DTC B0098 is set, replace the SDM.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
