The PASSENGER AIR BAG ON/OFF indicators are used to notify the driver when the Passenger Presence System (PPS) has enabled or disabled the instrument panel (I/P) inflator module. When the ignition is turned ON, the PPS module is supplied with voltage and commands both PASSENGER AIR BAG ON/OFF indicators ON for 5 seconds; then the PPS module conducts tests on the PPS components and circuits while both PASSENGER AIR BAG ON/OFF indicators are ON. If no malfunctions are detected, the PPS module will turn the PASSENGER AIR BAG indicator ON or OFF, depending on the status of the PPS. If a malfunction is detected, the PPS module will store a diagnostic trouble code (DTC), default the PPS to the OFF state, and communicate with the SDM that a DTC has been set. The SDM will request the instrument panel cluster (IPC) to turn the AIR BAG indicator ON to notify the driver of a PPS malfunction.

A history DTC maybe caused by an intermittent short or open in the ignition 1 circuit for the passenger AIR BAG ON/OFF indicator.

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 Passenger AIR BAG ON/OFF indicator

•	The PPS module

•	The Passenger AIR BAG ON/OFF indicator wiring harness connector

•	The PPS wiring harness connector

1. Perform PPS rezeroing procedure.
2. Ignition ON, with a scan tool check for DTCs.

⇒	If DTC B1797 is current, refer to DTC B1797.

3. Perform PPS sensitivity check as described in PPS rezeroing procedure.
4. Ignition ON, with a scan tool, observe the passenger seat belt status as the belt is buckled and unbuckled.

⇒	If passenger seat belt status does not change, replace passenger seat belt buckle.

5. Fasten the passenger seat belt.
6. Ignition ON, with a scan tool, observe that the filtered pressure sensor output is 39-64.

⇒	If filtered pressure sensor is not as indicated, replace passenger seat belt retractor.

⇒	If filtered pressure sensor is as indicated, replace the PPS seat sensor.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
