Rivet Nut Replacement
RIVET NUT REPLACEMENTWARNING:
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
- Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
- To reduce the risk of personal injury, do not use any memory saver devices.
CAUTION: If the safety canopy module has deployed, the tether cord rivet nut must be inspected and replaced if damaged before installing a new safety canopy.
NOTE:
- A typical rivet nut replacement is shown that is similar for all vehicles.
- The left-hand drive driver side is shown, all others are similar.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

1. Turn the ignition switch to OFF.
Vehicles built up to 03/2002
2. At the central junction box (CJB), located below the LH side of the instrument panel, remove the restraints control module (RCM) fuse F2.28 (10A) from the CJB.
Vehicles built 03/2002 onward
3. At the central junction box (CJB), located below the LH side of the instrument panel, remove the restraints control module (RCM) fuse F2.19 (10A) from the CJB.
All vehicles
4. WARNING: To avoid accidental deployment and possible personal injury, the backup power supply must be depleted before repairing or replacing any front or side air bag supplemental restraint system (SRS) components and before servicing, replacing, adjusting or striking components near the front or side air bag sensors or RCM, such as doors, instrument panel, console, door latches, strikers, seats and hood latches.
The side impact sensors (if equipped) are located at or near the base of the B-pillars and C-pillars.
To deplete the backup power supply energy, disconnect the battery ground cable and wait at least one minute. Be sure to disconnect auxiliary batteries and power supplies (if equipped).
Disconnect the battery ground cable and wait at least one minute.
5. Remove the A-pillar trim panel.
6. Remove the bolt and bracket for the tether cord from the A-pillar.
7. Position and secure the side air curtain tether cord and bracket assembly out of the way.
8. Using the appropriate service tool, sand the rivet nut shoulder until the shoulder surface is removed.
9. Punch the remaining portion of the rivet nut through the rivet nut hole.
10. NOTE: Use only Ford Motor Company factory-authorized replacement parts for rivet nut repair procedure.
Obtain the correct square shank rivet nut for the vehicle application from the Ford Master Parts Catalog, and insert it into the rivet nut hole.
11. Using a suitable rivet nut installing tool, install the rivet nut.
12. Position the A-pillar tether cord. Install the bolt. See the appropriate component removal and installation procedure or Specifications for the correct torque specification.
13. NOTE: The tether cord must be positioned correctly in place before installing the A-pillar trim panel.
Install the A-pillar trim panel.
14. WARNING: The restraint system diagnostic tool is for restraint system service only. Remove from vehicle prior to road use. Failure to remove could result in injury and possible violation of vehicle safety standards.
Make sure all restraint system diagnostic tool(s) that may have been installed during the repair have been removed from the vehicle and all SRS components are connected.
15. Turn the ignition switch from OFF to ON.
Vehicles built up to 03/2002
16. Install the RCM fuse F2.28 (10A) to the CJB.
Vehicles built 03/2002 onward
17. Install the RCM fuse F2.19 (10A) to the CJB.
All vehicles
18. WARNING: Be sure that nobody is in the vehicle and that there is nothing blocking or set in front of any air bag module when the battery ground cable is connected.
Connect the battery ground cable.
19. Prove out the supplemental restraint system (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 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 ON 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 a SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator and any SRS fault discovered must be diagnosed and repaired.
Clear all continuous DTCs from the restraints control module using a scan tool.
