DIAGNOSTIC FAULT INFORMATION






IMPORTANT: Always perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Testing and Inspection

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 side impact module - LF. 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 side impact module - LF connector which will short together both side impact module - LF 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

B0014 01
The side impact module - LF high and/or low circuit is short to voltage for 120 milliseconds.

B0014 02
The side impact module - LF high and/or low circuit is short to ground for 120 milliseconds.

B0014 04
The side impact module - LF high and/or low circuit is open for 120 milliseconds.

B0014 0D
The side impact module - LF deployment loop resistance is more than 3.9 ohms for 120 milliseconds.

B0014 0E
The side impact module - LF deployment loop resistance is less than 1.1 ohms for 120 milliseconds.

ACTION TAKEN WHEN THE DTC SETS
- The SDM commands the AIR BAG indicator ON via serial data communications.
- The SIR system is disabled and no deployments are allowed.

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
1. Ignition OFF, disconnect the side impact module - LF wiring harness connector located under the driver front seat.

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 side impact module - LF
- The side impact module wiring harness
- The SDM module
- The side impact module - LF wiring harness connector
- The side impact module wiring harness connector
- The SDM wiring harness connector

2. Connect the J 38715-A to the harness side of the side impact module - LF wiring harness connector. Use the PASSENGER INFLATOR connector located on the load tool.
3. Ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B0014 is set history.
- If DTC B0014 is current turn OFF the ignition and remove the SDM connector. Refer to SDM replacement in Repair Instructions for connector location.
- Test and repair both side impact module - LF high and low circuits for a short to voltage, short to ground, or open/low resistance. If all circuits test normal then replace the SDM.
4. Ignition OFF, disconnect and remove the J 38715-A. Then connect the side impact module - LF wiring harness connector. Remove the side impact module - LF connector. Use J 38715-30A to connect the J 38715-A to the harness side of the side impact module - LF connector. Use the PASSENGER INFLATOR connector located on the load tool.
5. Ignition ON, use a scan tool to observe the SIR DTC display. Verify DTC B0014 is set history.
- If DTC B0014 is current the replace the side impact module - LF wiring harness.
6. If DTC B0014 is history replace the side impact module - LF.
