This procedure covers the removal and replacement of side airbag modules located in the front seat backrests on a 2011-2014 Ford F-150 with 3.5L EcoBoost engine.

Warnings

Tools required

Parts

• Side airbag module (seat-mounted) × 1 — Use OEM Ford specification - driver or passenger specific
• Seat cover clips (if damaged during removal) × 5 — Ford OEM seat trim clips

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery terminal and isolate cable end away from battery post
4. Wait minimum 2 minutes for airbag system backup power to fully discharge
5. Identify which seat contains the faulty side airbag (driver or passenger side)
6. Move seat to full rearward position for access to front mounting bolts
7. Ensure you have a clean, flat workspace prepared to place removed airbag module face-up

Procedure

1. 1

   Remove seat mounting bolts
   Locate the four seat track mounting bolts (two front, two rear). Move seat forward to access rear bolts, then rearward to access front bolts. Remove all four bolts using appropriate socket. Note: These are high-torque safety-critical fasteners.
   Torque spec

   Mounting Bolts39 Nm (29 lb-ft)
2. 2

   Disconnect seat electrical connectors
   Tilt seat backward carefully to access underneath. Locate all electrical connectors: side airbag connector (yellow), seat position sensor, heated seat (if equipped), and power seat motor (if equipped). Press locking tabs and disconnect all connectors. Side airbag connector will have a yellow safety lock that must be released first.
   ⚠The side airbag connector is yellow and has a secondary lock. Do not force - release secondary lock first before pulling connector apart.
3. 3

   Remove seat from vehicle
   With assistance or using proper lifting technique, carefully lift seat assembly and remove from vehicle. Place seat on clean, protected work surface. Ensure seat is stable and will not tip over during work.
   ⚠Seat weighs approximately 50-80 lbs depending on options. Use proper lifting technique to avoid back injury.
4. 4

   Remove seat backrest side cover
   Locate the seat backrest side cover on the outboard side (door side) of the seat back. Remove trim cover by carefully prying at designated release points or removing retaining screws if present. The side airbag is mounted within the seat backrest frame on the outboard side.
   Torque spec

   Cover Screws12 Nm (9 lb-ft)
5. 5

   Access airbag module mounting location
   With side cover removed, locate the side airbag module mounted in a fabric sleeve or bracket within the seat backrest frame. The module will be oriented vertically along the outboard edge of the backrest. Note the airbag deployment direction (outward toward door) before removal.
6. 6

   Remove airbag module connector
   Locate the yellow airbag connector attached to the module. Release the secondary safety lock (typically a red or yellow sliding tab), then press the primary connector lock and carefully pull connector straight off the airbag module. Do not twist or bend connector pins.
   ⚠️Never use electrical test equipment on the airbag connector or module terminals. This can cause deployment.
7. 7

   Remove side airbag module mounting bolts
   Using T20 or T30 Torx bit (verify which is correct for your specific model year), remove the airbag module mounting bolts. Typically 2-3 bolts secure the module to the seat frame. Keep bolts organized for reinstallation.
   ℹ️Use correct Torx size to avoid stripping bolt heads. Module mounting bolts are typically T20 or T30.
   Torque spec

   Side Airbag Module Bolts7 Nm (5 lb-ft)
8. 8

   Remove airbag module from seat
   Carefully extract the side airbag module from the seat backrest frame and fabric sleeve. Handle module gently and avoid any impact or dropping. Immediately place module face-up (deployment side up) on clean, flat surface away from work area.
   ⚠️Place removed airbag module face-UP on a stable surface at least 10 feet away from people. Never place face-down.
9. 9

   Inspect mounting area and hardware
   Inspect the seat frame mounting points for damage, cracks, or deformation. Check fabric sleeve or mounting bracket for tears or damage. Verify new airbag module part number matches original exactly, including all suffix codes. Check that mounting bolts are not damaged or corroded.
10. 10

    Install new side airbag module
    Position new airbag module in seat backrest frame with deployment face oriented outboard (toward door side). Align module with mounting holes in seat frame. Ensure fabric sleeve or bracket properly surrounds module if applicable. Module should sit flush against frame.
    ⚠Verify correct orientation - deployment face must point outboard toward vehicle door. Incorrect installation will prevent proper deployment.
11. 11

    Install and torque module mounting bolts
    Install airbag module mounting bolts finger-tight, ensuring module is properly seated. Using calibrated torque wrench with appropriate Torx bit, torque bolts to specification in a cross-pattern if multiple bolts. Verify module is secure and does not move.
    ⚠Critical safety torque specification. Over-torque can damage module housing; under-torque can cause deployment issues. Use calibrated torque wrench.

12. 12

    Connect airbag module connector
    Carefully align yellow airbag connector with module terminals and push straight on until primary lock clicks. Engage secondary safety lock (slide lock into locked position). Gently tug on connector to verify it is fully locked - it should not pull off.
13. 13

    Reinstall seat backrest side cover
    Position seat backrest side cover over airbag module area. Ensure no wiring is pinched and airbag module is not contacted by cover screws. Install cover screws if applicable and secure all trim clips. Cover should fit flush without gaps.
    Torque spec

    Cover Screws12 Nm (9 lb-ft)
14. 14

    Reinstall seat in vehicle
    With assistance, carefully lift seat assembly and position over seat track mounting points. Align seat tracks with floor mounting holes. Reconnect all electrical connectors under seat: side airbag (yellow), seat sensors, heated seat, and power seat motor. Ensure yellow airbag connector secondary lock is engaged.
15. 15

    Install and torque seat mounting bolts
    Install all four seat track mounting bolts finger-tight. Using calibrated torque wrench, torque all four bolts to specification in a cross-pattern (front left, rear right, front right, rear left). Verify seat is solidly mounted with no movement.
    ⚠Seat mounting bolts are safety-critical. Improper torque can result in seat detachment during collision. Use calibrated torque wrench.

16. 16

    Reconnect battery and clear codes
    Reconnect negative battery terminal and torque to specification if applicable. Turn ignition to ON position (do not start engine). Airbag warning light will illuminate then should extinguish after approximately 6 seconds if system is functioning properly. Use professional scan tool to clear any stored airbag DTCs and verify no current faults exist.
    ℹ️Airbag system requires professional scan tool to properly clear codes and verify system readiness. Generic OBD-II scanners may not have full airbag functionality.

Reassembly

1. Verify all electrical connectors are fully seated with secondary locks engaged
2. Ensure seat operates through full range of motion without binding or interference
3. Confirm seat backrest recline function operates normally
4. Verify no tools or parts are left in or under seat
5. Test seat belt operation to ensure no interference with airbag deployment path

Verification

• Turn ignition to ON position - airbag warning light should illuminate briefly then extinguish within 6 seconds
• Use professional scan tool to verify no airbag diagnostic trouble codes are present
• Verify scan tool shows side airbag module is communicating properly with airbag control module
• Physically check that seat is solidly mounted with no movement or rattles
• Confirm all seat functions operate normally (power adjust, heated seat, recline)
• Verify seat backrest side cover is properly installed with no gaps or loose clips
• Professional recommendation: Have airbag system professionally verified before returning vehicle to service
