Diagnostic Fault Information
Circuit/System Description
If a malfunction is detected, a DTC will be stored in non-volatile memory. 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 air bags. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity, shorts to ground, and shorts to voltage. There are 2 shorting bars used within the module connector which will short together both high and low circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the air bag during servicing.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B0014 01, B0015 01, OR B0016 01, B0019 01 Stage 1, B0020 01 Stage 2, B0021 01, B0022 01, B0023 01
The air bag or pretensioner high and/or low circuit is shorted to voltage for 120 milliseconds.
B0014 02, B0015 02, OR B0016 02, B0019 02 Stage 1, B0020 02 Stage 2, B0021 02, B0022 02, B0023 02
The air bag or pretensioner high and/or low circuit is shorted to ground for 120 milliseconds.
B0014 04, B0015 04, OR B0016 04, B0019 04 Stage 1, B0020 04 Stage 2, B0021 04, B0022 04, B0023 04
The air bag or pretensioner high and/or low circuit is open for 120 milliseconds.
B0014 0D, B0015 0D, OR B0016 0D, B0019 0D Stage 1, B0020 0D Stage 2, B0021 0D, B0022 0D, B0023 0D
The air bag or pretensioner deployment loop resistance is greater than 3.9 ohms for 120 milliseconds.
B0014 0E, B0015 0E, OR B0016 0E, B0019 0E Stage 1, B0020 0E Stage 2, B0021 0E, B0022 0E, B0023 0E
The air bag or pretensioner deployment loop resistance is less than 1.1 ohms for 120 milliseconds.
Action Taken When the DTC Sets
* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator.
* The SDM will store a DTC, however if an event occurs the system will still attempt deployments.
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
Important: When removing the connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector.
* Buckle pretensioner
* Air bag
* SDM
* Buckle pretensioner wiring harness connector
* Air bag wiring harness connector
* SDM wiring harness connector
The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly.
1. Verify that the appropriate air bag or pretensioner connector and CPA are engaged.
• If the above condition is not found, make the appropriate repair.
2. Ignition OFF, disconnect the harness connector at the appropriate air bag or pretensioner.
3. With the appropriate load tool adaptor, connect special tool J 38715-A in place of the air bag or pretensioner.
4. Ignition ON, with a scan tool, verify the appropriate DTC is set as current.
• If the DTC is not set or is set as history, cycle ignition OFF, disconnect the adapter and J 38715-A , reconnect the harness connector at the air bag or pretensioner, and cycle the ignition ON. If the DTC resets after reconnecting the air bag or pretensioner, replace the air bag or pretensioner.
5. Ignition OFF, disconnect special tool J 38715-A or SA9409Z-A and the adaptor.
6. Disconnect the harness connector at the SDM.
7. Ignition ON, test for less than 1 volt between the SDM high control circuit terminal and ground.
