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 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 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 ohms 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 ohms for 120 milliseconds.


Action Taken When the DTC Sets

* The SDM commands the AIR BAG indicator ON.
* The SDM will store a DTC, if an 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.
