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 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.

Important: 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 inside rearview mirror

•	The PPS module

•	The SDM module

•	The inside rearview mirror wiring harness connector

•	The PPS module wiring harness connector

•	The SDM wiring harness connector

1. Ignition OFF, disconnect the PPS module connector located under the passenger seat.
2. Disconnect the inside rearview mirror connector located on the back side of the mirror.
3. Test the inside rearview mirror 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 passenger ON and OFF indicator control circuits between the inside rearview mirror 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 inside rearview mirror connector. With the passenger front seat empty, verify the test lamp illuminates.

⇒	If test lamp does not illuminate, replace the PPS.

⇒	If test lamp illuminates, replace the inside rearview mirror.
