Glossary of Terms Used While Performing Tests

Air Bag/Pretensioner Simulator
Air bag/pretensioner simulators are used to simulate the equivalent resistance of an air bag module or safety belt retractor pretensioner during certain diagnostic procedures.

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

Deactivate the System
Deactivate the system means to carry out the deactivation procedure. Go to the Deactivation Procedure. Deactivation Procedures

Prove Out the System
Prove out the system means to turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules and safety belt retractor pretensioners installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag SRS fault is present, the air bag indicator will either:
^ fail to light
^ remain lit continuously
^ flash

The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the time required for the RCM to complete the testing of the SRS If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.

Reactivate the System
Reactivate the system means to carry out the reactivation procedure. Go to the Reactivation Procedure. Reactivation Procedures

Reconnect the System
Reconnect the system means to reconnect all system components. Go to the Air Bag System Reconnect Checklist.

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.

Verify the System
Verify the system means to prove out the system with simulators installed in place of the SRS components.
