Silverado
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 volts.
