DTC B1367

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using the diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions) provides an overview of each diagnostic category.

DTC Descriptor
DTC B1367
- Passenger Pretensioner Deployment Loop Resistance High

Diagnostic Fault Information





Circuit/System Description

During a side or frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop in order to deploy the seat belt pretensioner - RF. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. A shorting bar used within the seat belt pretensioner - RF connector which will short together both seat belt pretensioner - RF high and low circuits when the connector is disconnected. This will help to prevent unwanted deployment of the inflator module during servicing.

Conditions for Running the DTC

Ignition voltage is between 9-16 volts.

Conditions for Setting the DTC

The seat belt pretensioner - RF deployment loop resistance is more than 3.54 ohms.

Action Taken When the DTC Sets

The SDM commands the AIR BAG indicator ON.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used.
* A history DTC will clear once 255 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.

* The I/P module
* The SDM module
* The I/P wiring harness connector
* The SDM wiring harness connector

1. Ignition OFF, disconnect the seat belt pretensioner - RF in-line connector.
2. Disconnect the SDM connector. Refer to SDM replacement in Repair Instructions for connector location.
3. Test the high and low circuits between the SDM and seat belt pretensioner - RF for a open/high resistance. Verify that a open/high resistance does not exist.

• If the above condition is found make the appropriate repair.

4. If all circuits test normal then replace the SDM.
5. Ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B1367 is set current.

• Replace the seat belt pretensioner - RF.

Repair Instructions

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