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 air bag 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 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 air bag or seat belt retractor pretensioner high and/or low control 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 air bag or seat belt retractor pretensioner high and/or low control 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 air bag or seat belt retractor pretensioner high and/or low control circuit is open for 120 milliseconds.
B0014 0D, B0015 0D, B0016 0D, B0019 0D, B0020 0D, B0021 0D, B0022 0D, B0023 0D
The air bag or seat belt retractor pretensioner deployment loop resistance is greater than 3.9 ohms for 120 milliseconds.
B0014 0E, B0015 0E, B0016 0E, B0019 0E, B0020 0E, B0021 0E, B0022 0E, B0023 0E
The air bag or seat belt retractor pretensioner 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.
* 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 fault-free ignition cycles have occurred.
