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. Ignition OFF, disconnect the PPS module connector located under the passenger seat.
2. Disconnect the Passenger AIR BAG ON/OFF Indicator connector.
3. Test the Passenger AIR BAG ON/OFF indicator ignition 1 voltage circuit for a short to ground, a high resistance, or an open. Verify that a short to ground, a high resistance, or an open does not exist.

⇒	If any of the above conditions are found make the appropriate repair.

4. Test both ON and OFF indicator control circuits between the Passenger AIR BAG ON/OFF indicator and the PPS for a short to voltage, high resistance, or an open. Verify that a short to voltage, a high resistance, or an open does not exist.

⇒	If any of the above conditions are found make the appropriate repair.

5. Reconnect the PPS connector then turn the ignition ON, engine OFF. Then connect a test lamp between the ignition 1 voltage circuit and Passenger Air Bag OFF indicator control circuit on the Passenger AIR BAG ON/OFF indicator connector. With the passenger front seat empty verify the test lamp illuminate.

⇒	If test lamp does not illuminate replace the PPS.

⇒	If test lamp illuminate replace the Passenger AIR BAG ON/OFF Indicator .

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
