Circuit/System Description
The PASSENGER AIR BAG ON/OFF indicators are used to notify the driver when the Passenger Presence System (PPS) has enabled or disabled the I/P inflator module. When the ignition is turned ON, the PPS illuminates the PASSENGER AIR BAG ON/OFF indicators for 5 seconds. The PPS module conducts tests on the PPS components and circuits while the PASSENGER AIR BAG ON/OFF indicators are illuminated. If no malfunctions are detected, the PPS module will illuminate 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 IPC to illuminate the AIR BAG indicator to notify the driver of a PPS malfunction.

Circuit/System Verification
With the passenger seat occupied and unoccupied the inflatable restraint passenger air bag on/off indicator should switch states within 5 seconds.
Circuit/System Testing
Important: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
• Driver information display assembly. • Driver information display assembly wiring harness.
- Ignition OFF, disconnect the harness connector at the driver information display.
- Ignition ON, verify a test lamp illuminates between the ignition circuit terminal 9 and ground.
- Connect a test lamp between the control circuit terminal 13 and the ignition circuit terminal 9.
- With the passenger seat occupied and unoccupied the test lamp should switch states within 5 seconds.
- Connect a test lamp between the control circuit terminal 12 and the ignition circuit terminal 9.
- With the passenger seat occupied and unoccupied the test lamp should switch states within 5 seconds.
- If all circuits test normal, replace the driver information display.
| ⇒ | If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. |
| ⇒ | If the test lamp does not change state, test the control circuit for an open, short to ground, or short to voltage. If all circuits test normal replace the IPC. |
| ⇒ | If the test lamp does not change state, test the control circuit for an open, short to ground, or short to voltage. If all circuits test normal replace the IPC. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
