B001B CHEVROLET Meaning
During a side or frontal collision with sufficient force, the Inflatable Restraint Sensing and Diagnostic Module (SDM) will allow current to flow through the deployment loop to deploy an airbag or pretensioner. There are 2 shorting bars that will short the control circuits together when the connector is disconnected. This helps prevent unwanted deployment of the airbag or pretensioner during maintenance.
