Supplemental Restraint System (SRS) Deactivation and Reactivation






Deactivation

WARNING: Always carry or place a live air bag module with the air bag and deployment door/trim cover/tear seam pointed away from the body. Do not set a live air bag module down with the deployment door/trim cover/tear seam face down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

WARNING: Never probe the electrical connectors on safety belt buckle/retractor pretensioners or adaptive load limiting retractors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors, which increases the risk of serious personal injury or death.

WARNING: If a vehicle has been in a crash, inspect the restraints control module (RCM) and the impact sensor (if equipped) mounting areas for deformation. If damaged, restore the mounting areas to the original production configuration. A new RCM and sensors must be installed whether or not the air bags have deployed. Failure to follow these instructions may result in serious personal injury or death in a crash.

WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.

WARNING: To reduce the risk of accidental deployment, do not use any memory saver devices. Failure to follow this instruction may result in serious personal injury or death.

NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition switch is ON.

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

All vehicles

1. Turn all vehicle accessories OFF.

2. Turn the ignition switch to OFF.

3. At the Smart Junction Box (SJB), located below the LH side of the instrument panel, remove the cover and the RCM fuse 32 (10A) from the SJB.

4. Turn the ignition ON and visually monitor the air bag warning indicator for at least 30 seconds. The air bag warning indicator will remain illuminated continuously (no flashing) if the correct RCM fuse has been removed. If the air bag warning indicator does not remain illuminated continuously, remove the correct RCM fuse before proceeding.

5. Turn the ignition OFF.

6. WARNING: Always deplete the backup power supply before repairing or installing any new front or side air bag supplemental restraint system (SRS) component and before servicing, removing, installing, adjusting or striking components near the front or side impact sensors or the restraints control module (RCM). Nearby components include doors, instrument panel, console, door latches, strikers, seats and hood latches.

Refer to the Description and Operation of Air Bag Systems for location of the RCM and impact sensor(s).

To deplete the backup power supply energy, disconnect the battery ground cable and wait at least 1 minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).

Failure to follow these instructions may result in serious personal injury or death in the event of an accidental deployment.

Disconnect the battery ground cable and wait at least one minute.

7. Remove the driver air bag module. Refer to Driver Air Bag Module Driver Air Bag Module.

8. Open the glove compartment door.

9. Release the dampening strut from the LH side of glove compartment door and lower door fully.

10. NOTE: Taurus X shown, Taurus and Sable similar.

NOTE: RH shown, LH similar.

Through the glove compartment opening, disconnect the 2 passenger air bag module electrical connectors.





11. From under the rear of the passenger seat, slide and disengage the passenger seat side air bag module electrical connector locking clip, and then release the tab and disconnect the passenger seat side air bag module electrical connector.





12. From under the rear of the driver seat, slide and disengage the driver seat side air bag module electrical connector locking clip, and then release the tab and disconnect the driver seat side air bag module electrical connector.

7. Install the passenger side D-pillar trim panel.
- Verify the safety belt retractor operates without excessive effort or binding.





8. NOTE: Headliner removed for clarity.

Connect the driver side safety canopy module electrical connector.





9. Install the driver side D-pillar trim panel.
- Verify the safety belt retractor operates without excessive effort or binding.





All vehicles

10. Connect the driver seat side air bag module electrical connector and then slide and engage the seat side air bag electrical connector locking clip.





11. Connect the passenger seat side air bag module electrical connector and then slide and engage the seat side air bag electrical connector locking clip.





12. NOTE: Taurus X shown, Taurus and Sable similar.

NOTE: RH electrical connector shown, LH electrical connector similar.

Connect the 2 passenger air bag module electrical connectors.





13. Attach the dampening strut to the LH side of glove compartment door.

14. Close glove compartment door.

15. Install the driver air bag module. Refer to Driver Air Bag Module Driver Air Bag Module.

16. Turn the ignition switch from OFF to ON.

17. Install the RCM fuse 32 (10A) to the SJB and install the cover.

18. WARNING: Make sure no one is in the vehicle and there is nothing blocking or placed in front of any air bag module when the battery is connected. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

Connect the battery ground cable.

19. Prove out the SRS as follows:

Turn the ignition key from ON to OFF. Wait 10 seconds, then turn the key back to ON and visually monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator will illuminate continuously for approximately 6 seconds and then turn off. If an air bag SRS fault is present, the air bag warning indicator will:

- 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 ON position. This is the time required for the RCM to complete the testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime will sound in a pattern of 5 sets of 5 beeps. If this occurs, the air bag warning indicator and any SRS fault discovered must be diagnosed and repaired.

Clear all continuous DTCs from the RCM and Occupant Classification System Module (OCSM) using the scan tool.
