Procedure

1. 1

   Remove seat from vehicle (for seat-mounted side airbag)
   If replacing seat-mounted side airbag: Move seat fully forward, then fully rearward to access all mounting bolts. Remove the four seat mounting bolts using appropriate socket. Disconnect seat electrical connectors under seat (belt tensioner, occupancy sensor, heater if equipped). Carefully remove seat from vehicle and place on clean work surface. If replacing curtain airbag, skip to step 3.
   ⚠Seats are heavy (60-80 lbs). Use proper lifting technique or get assistance to avoid back injury.

2. 2

   Remove seat upholstery to access side airbag module
   For seat-mounted airbag: Locate the side airbag cover on outboard side of seat back. The airbag is integrated into the seat cover with a tear seam. From the rear of seat back, use hog ring pliers to carefully remove hog rings securing upholstery to seat frame. Work methodically around the airbag area. Peel back upholstery enough to expose the side airbag module mounting location. The module will be visible as a flat rectangular unit mounted to the seat frame.
3. 3

   Remove pillar trim panels (for curtain airbag)
   If replacing curtain airbag: Remove A-pillar trim by pulling away from body, releasing retaining clips. Remove B-pillar upper and lower trim panels using trim removal tools. Remove C-pillar trim panel. Remove headliner grab handles by removing cover caps and screws. Carefully pull down headliner edge along affected side to expose curtain airbag mounting points. The curtain airbag is a long inflatable tube running from A-pillar to C-pillar.

4. 4

   Disconnect airbag electrical connector
   Locate the airbag module electrical connector. It will have a bright yellow or orange connector body (typical Ford airbag circuit color coding). Press the connector lock tab and carefully disconnect. Do NOT pull on wires. The connector should have a shorting bar that automatically engages when disconnected. Secure the vehicle-side connector away from the module.
   ⚠️Verify 3+ minutes have elapsed since battery disconnect before touching any connectors. Premature contact can cause deployment.
5. 5

   Remove side airbag module mounting fasteners
   For seat-mounted airbag: Remove the Torx bolts (typically T30 or T40) securing the side airbag module to the seat frame. There are usually 2-4 mounting points. For curtain airbag: Remove the mounting bolts along the roof rail at A-pillar, B-pillar, and C-pillar attachment points. Use appropriate Torx bit as specified. Keep all fasteners organized for reinstallation.
   ⚠Support curtain airbag module during removal of final fastener as it may shift position when released.

6. 6

   Remove old airbag module from vehicle
   Carefully extract the airbag module from its mounting location. For seat airbag, remove through the upholstery opening. For curtain airbag, guide the long module out from behind headliner, feeding through pillar areas. Place the removed module face-up on a clean, padded surface in a secure location away from the work area. Never place face-down or place objects on top of module.
7. 7

   Inspect mounting points and wiring harness
   Examine seat frame or roof rail mounting points for any damage, cracks, or deformation. Check that mounting threads are clean and undamaged. Inspect the vehicle wiring harness and connector for corrosion, damage, or pushed-back pins. Clean connector if necessary with electrical contact cleaner. Verify connector locking tabs are intact. Check that seat frame or roof rail is properly grounded if applicable.
   ⚠Do NOT use compressed air to clean airbag connectors as this can cause static discharge. Use only approved contact cleaner.
8. 8

   Prepare new airbag module for installation
   Remove new airbag module from packaging. Verify part number matches original and is correct for vehicle position. Inspect module for any shipping damage. The connector should have a shorting clip installed - leave this in place until ready to connect. Orient the module to match original positioning, noting any directional arrows or 'UP' markings on the module.
   ⚠️Never drop or impact an airbag module. Even minor impacts can damage the initiator or propellant, causing malfunction.
9. 9

   Install new airbag module to mounting points
   Position new airbag module in mounting location. For seat airbag, align with frame mounting holes ensuring tear seam faces outboard. For curtain airbag, route along roof rail ensuring proper positioning at A, B, and C pillars. Start all mounting bolts by hand first to verify proper thread engagement. Using calibrated torque wrench with appropriate Torx bit, tighten all Side Airbag Module Bolts to exactly 7.0 Nm (5.0 lb-ft) in a cross-pattern sequence.
   ⚠️CRITICAL: Use only calibrated torque wrench. Under-torquing can allow module movement in crash; over-torquing can damage module housing or alter deployment characteristics.

    Connect airbag electrical connector
    Remove the shorting clip from the new airbag module connector. Align the vehicle harness connector with the module connector, ensuring proper pin alignment. Push connectors together firmly until you hear and feel a positive click. Verify the connector lock tab is fully engaged. Gently tug on connector to confirm it is locked - it should not separate. Ensure no wires are pinched or under strain.
    ⚠️Connector must be fully seated and locked. Partial connection creates high resistance that can prevent deployment or cause inadvertent deployment.
11. 11

    Reinstall seat upholstery or pillar trim panels
    For seat-mounted airbag: Carefully reposition upholstery over airbag module, ensuring tear seam is properly aligned and no fabric is caught in module edges. Reinstall hog rings using hog ring pliers to secure upholstery to seat frame, working around module area. Verify upholstery lays flat with no bunching over airbag. For curtain airbag: Tuck curtain airbag behind headliner, reposition headliner edge and install grab handles with screws torqued to specification. Reinstall C, B, and A pillar trim panels, ensuring all clips seat properly.
