GLOSSARY

Disconnect the Component
Disconnect the component means to disconnect the component vehicle harness connector, not to remove the component. Do not reconnect a disconnected component unless instructed to do so.

Deactivate the Supplemental Restraint System (SRS)
Deactivate the SRS means to disconnect the battery, remove the restraints control module (RCM) fuse, disconnect all SRS components and reconnect the battery.

Depower the Supplemental Restraint System (SRS)
Depower the SRS means to disconnect the battery and remove the RCM fuse.

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

Install a New Component
Install a new component means to remove the existing component and install a new authorized part obtained from Ford Customer Service Division.

Prove Out the Supplemental Restraint System (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. The instrument cluster (IC) module will continuously illuminate the air bag warning indicator for approximately 6 seconds and then turn off. If an SRS fault is present, the air bag warning indicator will either fail to light or remain lit continuously. If the air bag warning indicator is inoperative and an SRS fault exists, the IC module will automatically sound a chime in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator will need to be repaired before diagnosis can continue.

Reactivate the Supplemental Restraint System (SRS)
Reactivate the SRS means to disconnect the battery, reconnect all SRS components, install the RCM fuse and reconnect the battery.

Reconnect the Supplemental Restraint System (SRS)
Reconnect the SRS means to reconnect all disconnected SRS components.

Repower the Supplemental Restraint System (SRS)
Repower the SRS means, turn the ignition ON, install the RCM fuse and connect the battery ground cable.

Secondary Air Bag Warning
The secondary air bag warning is an audible tone 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 problem and warning light 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.

Verify the Supplemental Restraint System (SRS)
Verify the SRS means to prove out the SRS with all SRS components in place and connected.
