Deployment Loop

The deployment loop is made up of the RCM  , deployable device, air bag(s), safety belt pretensioners (safety canopies, deployable steering columns, load limiter retractor, adaptive tether, adaptive vent, if equipped) and associated circuits. Each deployable device contain an initiating device called a squib. Air bag/safety canopies modules can contain more than one squib, some vehicles may have up to 4 squibs in one air bag module. Squibs are often referred to as loops during the diagnostic process. A squib (igniter) is a device designed to convert electrical energy to the heat energy necessary to deploy a pyrotechnic restraints system device. Squibs are often referred to as loops during the diagnostic process.
