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 volts.

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 control circuit is shorted to voltage for 2 seconds.

The inflatable restraint module high and/or low control circuit is shorted to ground for 2 seconds.

B0014 08, B0015 08, B0016 08, B0019 08, B0020 08, B0021 08, B0022 08, B0023 08

The inflatable restraint module high and/or low control circuit is open for 2 seconds.

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 5.5 ohms for 2 seconds.

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

Circuit/System Testing

Important: Refer to SIR Service Precautions.

When removing connectors inspect for damage or corrosion. Damage or corrosion to the following requires repair or replacement of the affected component/connector:

•	Pretensioner

•	Inflatable restraint module

•	SDM module

•	Inflatable restraint module wiring harness connector

•	SDM wiring harness connector

Important: 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. Ignition OFF, disconnect the harness connector at the appropriate inflatable restraint module.
2. With the appropriate load tool adaptor, connect J 38715-A in place of the inflatable restraint module.
3. 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 inflator restraint module, and cycle the ignition ON. If the DTC resets after reconnecting the module, replace the inflator restraint module.

4. Ignition OFF, disconnect J 38715-A and the appropriate adaptor.
5. Disconnect the appropriate harness connector at the SDM.
6. Ignition ON, test for less than 1 volt between the appropriate control circuit listed below and ground:
