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 bag module. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity, shorts to ground, and shorts 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 inflator module during servicing.
Conditions for Running the DTC
Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC
B0014 01, B0015 01, B0016 01, B0018 01, B0019 01, B0020 01, B0021 01, B0022 01, B0023 01, B0025 01
The air bag module high and/or low circuit is short to voltage for 120 milliseconds.
B0014 02, B0015 02, B0016 02, B0018 02, B0019 02, B0020 02, B0021 02, B0022 02, B0023 02, B0025 02
The air bag module high and/or low circuit is short to ground for 120 milliseconds.
B0014 04, B0015 04, B0016 04, B0018 04, B0019 04, B0020 04, B0021 04, B0022 04, B0023 04, B0025 04
The air bag module high and/or low circuit is open for 120 milliseconds.
B0014 0D, B0015 0D, B0016 0D, B0018 0D, B0019 0D, B0020 0D, B0021 0D, B0022 0D, B0023 0D, B0025 0D
The air bag module deployment loop resistance is more than 3.9 ohms for 120 milliseconds.
B0014 0E, B0015 0E, B0016 0E, B0025 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E, B0025 0E
The airbag module 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 SDM will store a DTC, if event occurs system will still attempt deployments. |
Conditions for Clearing the DTC
| • | The condition responsible 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 connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
• The pretensioner • The air bag module • The SDM module • The air bag wiring harness connector • The SDM wiring harness connector
- Ignition OFF, disconnect the harness connector at the applicable airbag module. Refer to the applicable airbag module replacement procedure.
- With the applicable adaptor, connect J 38715-A .
- Ignition ON, with a scan tool, verify DTC is set as current.
- Ignition OFF, disconnect J 38715-A and the applicable adaptor.
- Ignition ON, test for less than 1 volt between the applicable HI circuit and ground.
- Test for less than 1 volt between the applicable LOW circuit and ground.
- Ignition OFF, test for infinite resistance between the applicable HI circuit and ground.
- Test for infinite resistance between the applicable LOW circuit and ground.
- Disconnect the harness connector at the SDM.
- Test for less then 1 ohm of resistance between the SDM connector and the airbag module connector HI circuit.
- Test for less then 1 ohm of resistance between the SDM connector and the airbag module connector LOW circuit.
- If all circuits test normal, replace the SDM.
| ⇒ | If DTC is not set or is set as history, replace the applicable airbag module. |
| ⇒ | If not the specified range, test the circuit for a short to voltage. |
| ⇒ | If not the specified range, test the circuit for a short to voltage. |
| ⇒ | If not the specified range, test the circuit for a short to ground. |
| ⇒ | If not the specified range, test the circuit for a short to ground. |
| ⇒ | If not the specified range, test the circuit for an open/high resistance. |
| ⇒ | If not the specified range, test the circuit for an open/high resistance. |
