DTC Descriptors
DTC 3003-305C
- Passenger Presence Sensor Circuit

Circuit/System Description

The passenger presence system (PPS) is used to monitor the profile of any occupant that is sitting in the front passenger seat and communicates the profile classification to the inflatable restraint sensing and diagnostic module (SDM). The SDM will either enable or suppress the deployment of the passenger instrument panel air bag based on the profile classification of the occupant. If the passenger presence module detects DTC 300A, 301A, 303A-303E, 305A-305C or 3003-3059 within itself, the passenger presence module will then communicate to the SDM through a dedicated serial data circuit that a PPS fault is present. The SDM will set DTC B0081 indicating a problem within the PPS and suppress the deployment of the passenger instrument panel air bag and illuminate the AIR BAG indicator.

Conditions for Running the DTC

Ignition voltage is between 9-16 V.

Conditions for Setting the DTC

The passenger presence module has detected an internal fault.

Action Taken When the DTC Sets

* The passenger presence module will set a DTC, and then communicate with the SDM.
* The SDM will set DTC B0081.
* The SDM will disable the passenger instrument panel air bag module deployment loop.
* The passenger presence module will illuminate the passenger air bag status OFF indicator.
* The SDM requests the instrument cluster to illuminate the AIR BAG warning indicator.

Conditions for Clearing the DTC

* The condition for setting the DTC no longer exists.
* A history DTC will clear once 100 malfunction-free ignition cycles have occurred.

Circuit/System Testing

Note: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.

* Passenger presence module
* Passenger presence module wiring harness connector

1. Verify that DTC 2001-2054 or 202A-202E is not set.

• If the DTC is set, refer to DTC 2001-2054 or 202A-202E (DTC 2001).

2. Verify that DTC 3003-3059 is not set.

• If the DTC is set, replace the passenger presence sensor.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
