DTC Descriptor
DTC B0092
- Passenger Presence System Performance
Diagnostic Fault Information
Circuit/System Description
When the ignition is turned ON, the Inflatable Restraint Sensing and Diagnostic Module performs tests to diagnose critical malfunctions within itself. When the Inflatable Restraint Sensing and Diagnostic Module has completed the power-up mode, the Inflatable Restraint Sensing and Diagnostic Module will establish communication with the Passenger Presence Module. The Passenger Presence Module module will respond by illuminating both the PASSENGER AIR BAG ON/OFF indicators for 5 seconds. The Inflatable Restraint Sensing and Diagnostic Module will transmit a request message to the Passenger Presence Module module to receive the Passenger Presence Module verification ID. The Passenger Presence Module module will transmit the verification ID to the Inflatable Restraint Sensing and Diagnostic Module and the Inflatable Restraint Sensing and Diagnostic Module will compare the ID received to data stored in memory. The Inflatable Restraint Sensing and Diagnostic Module will also set DTC B0092 to notify the driver that the Passenger Presence Module module has a current malfunction present. When the Inflatable Restraint Sensing and Diagnostic Module detects that the Passenger Presence Module module has set any one of the following DTCs 023, 024, 063, 064, or 065, the Inflatable Restraint Sensing and Diagnostic Module will disable the passenger instrument panel air bag deployment loop, set DTC B0092, and illuminate the AIR BAG indicator.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
* The Passenger Presence Module module has a current fault.
* The Inflatable Restraint Sensing and Diagnostic Module has not received the correct verification ID from the Passenger Presence Module module.
Action Taken When the DTC Sets
* The Inflatable Restraint Sensing and Diagnostic Module disables the passenger instrument panel air bag deployment loop.
* The Inflatable Restraint Sensing and Diagnostic Module requests the Instrument Cluster to illuminate the AIR BAG indicator.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.
Diagnostic Aids
Note: DTC B0092 will also set if the Passenger Presence Module module has a current malfunction, and has set any one of the following DTCs 023, 024, 064, or 065. The Inflatable Restraint Sensing and Diagnostic Module will set DTC B0092 as current and command the AIR BAG indictor ON. This is done to notify the driver of any Passenger Presence Module malfunctions. When DTC B0092 is present, it is important to check the Passenger Presence Module module for any current DTC. Refer to Passenger Presence System Flash Code Procedures Component Tests and General Diagnostics. Any current Passenger Presence Module module DTCs must be diagnosed before performing this diagnostic procedure.
DTC B0092 is an indication that the Inflatable Restraint Sensing and Diagnostic Module has received an incorrect Passenger Presence Module verification ID or has lost communication with the Passenger Presence Module module. The Inflatable Restraint Sensing and Diagnostic Module will continue to request the verification ID from the Passenger Presence Module module for 5 seconds. If the Inflatable Restraint Sensing and Diagnostic Module does not receive the correct verification ID from the Passenger Presence Module module within 5 seconds, the Inflatable Restraint Sensing and Diagnostic Module will set the DTC as current, illuminate the AIR BAG indicator, and disable the passenger instrument panel air bag deployment loop.

1. Ignition ON, observe the function of the passenger air bag ON and OFF indicators. The passenger air bag ON and OFF indicators should illuminate.
• If the passenger air bag ON/OFF status indicators do not illuminate refer to Air Bag Indicator Circuit Malfunction (Driver) Air Bag Indicator Circuit Malfunction (Driver)Air Bag Indicator Circuit Malfunction (Passenger) Air Bag Indicator Circuit Malfunction (Passenger).
2. When DTC B0092 is present, it is important to check the Passenger Presence Module for any current DTCs. Refer to Passenger Presence System Flash Code Procedures Component Tests and General Diagnostics. Any current Passenger Presence Module DTCs must be diagnosed before performing this diagnostic procedure.
3. Ignition OFF, disconnect the harness connector at the Passenger Presence Module.
4. Test for less than 1 ohm between the ground circuit terminal 5 and ground.
• If greater than the specified range, test the ground circuit for an open/high resistance
5. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 9 and ground.
• If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
6. Disconnect the harness connector at the Inflatable Restraint Sensing and Diagnostic Module.
7. Test for infinite resistance between the serial data link terminal 18 and ground.
• If less than the specified value, test the serial data link for a short to ground.
8. Test for less than 1 ohm between the Passenger Presence Module serial data link terminal 18 and the Inflatable Restraint Sensing and Diagnostic Module serial data link terminal 2.
• If greater than the specified range, test the serial data link for an open/high resistance.
9. Ignition ON, test for less than 1-volt between the Passenger Presence Module serial data link terminal 18 and ground.
• If greater than the specified range, test the serial data link for a short to voltage.
10. If all circuits test normal, replace the Passenger Presence Module.
