Restraint System Diagnostic Tool
Restraint system diagnostic tools are used to simulate air bag module connections to the system.

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 perform the deactivation procedure. Refer to 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 installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag Supplemental Restraint System (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 Restraints Control Module (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 tone bursts. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.

Reactivate the System
Reactivate the system means to perform the reactivation procedure. Refer to Reactivation Procedure. Reactivation Procedures

Reconnect the System
Reconnect the system means to reconnect all system components. Refer to 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 restraint system diagnostic tools for the air bag modules in place of components.

Air Bag System Reconnect Checklist
The checklist below should be completed following diagnosis or repair of any air bag system concern.
1. Is the air bag system connector at the base of the steering column connected?
2. Are the air bag modules connected?
3. Are the side air bag electrical connectors beneath the front seats connected?
4. Is the Restraints Control Module (RCM) connected?
5. Is the vehicle battery connected?
