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.
