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 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.
