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 air bag. There are 2 shorting bars used within the module connector which will short together control



circuits, when the connector is disconnected. This will help to prevent unwanted deployment of the air bag or pretensioner during servicing.



Conditions for Running the DTC



Ignition voltage is between 9-16 V.
