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 an inflatable restraint module. 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 V.

Conditions for Setting the DTC

B0014 01, B0015 01, B0016 01, B0019 01, B0020 01, B0021 01, B0022 01, B0023 01

The inflatable restraint module high and/or low circuit is shorted to voltage for 120 milliseconds.

B0014 02, B0015 02, B0016 02, B0019 02, B0020 02, B0021 02, B0022 02, B0023 02

The inflatable restraint module high and/or low circuit is shorted to ground for 120 milliseconds.

B0014 04, B0015 04, B0016 04, B0019 04, B0020 04, B0021 04, B0022 04, B0023 04

The inflatable restraint module high and/or low circuit is open for 120 milliseconds.

B0014 0D, B0015 0D, B0016 0D, B0019 0D, B0020 0D, B0021 0D, B0022 0D, B0023 0D

The inflatable restraint module deployment loop resistance is greater than 3.9 ohm for 120 milliseconds.

B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E

The inflatable restraint module deployment loop resistance is less than 1.1 ohm for 120 milliseconds.

Action Taken When the DTC Sets

* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator ON.
* 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

Note:
* Refer to SIR Service Precautions (Technician Safety Information).
* When removing connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:

- The pretensioner
- The inflatable restraint module
- The SDM
- The inflatable restraint module wiring harness connector
- The SDM wiring harness connector


Note: 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 inflator restraint module connector and the CPA are engaged.

• If the connector or CPA is not properly engaged, make the appropriate repair.

2. Ignition OFF, disconnect the harness connector at the appropriate inflator restraint module.
3. With the appropriate load tool adaptor, connect J 38715-A in place of the inflator restraint module.
4. Ignition ON, with a scan tool, verify DTC is set as current.

• If the DTC is not set or is set as history, cycle ignition OFF, disconnect the J 38715-A and the adapter, reconnect the harness connector at the inflatable restraint module and cycle the ignition ON. If the DTC resets after reconnecting the module, replace the inflatable restraint module.

5. Disconnect the harness connector at the SDM.
6. Ignition ON, test for less than 1 V between the appropriate high control circuit terminal and ground.
