Depower the SRS/Repower the SRS
Depower/Repower the SRS means to disconnect the battery and remove/install the restraints control module (RCM) fuse.

Deployment Loop
The deployment loop is made up of the RCM, deployable device, air bag(s), safety belt pretensioners (safety canopies/side air curtains, deployable steering columns, load limiting retractor, adaptive tether, adaptive vent, if equipped) and associated circuits.

Prove Out the SRS
Prove out the SRS means to turn the ignition switch from the OFF to the ON position and visually monitor the air bag warning indicator with all SRS components connected. For information on the air bag warning indicator and prove out, refer to the Prove Out Procedure. Prove Out Procedure

Secondary Air Bag Warning (Chime)
The secondary air bag warning chime is an audible fault format that consists of 5 sets of 5 tone bursts, with each set of 5 tone bursts separated by a 5-second quiet period. One tone burst cycle will consist of one-second ON and one-second OFF. The tone pattern will repeat periodically until the SRS concern and warning indicator concern are repaired.

Squib
A squib (igniter) is a device designed to convert electrical energy to the heat energy necessary to deploy a pyrotechnic restraints system device.
