Replace the side curtain airbag module located in the roof rail or seat-mounted side airbag on a 2015 Kia Forte. This is a safety-critical procedure requiring proper deployment system handling and OBD diagnostic tools.

Warnings

Tools required

Parts

• Side airbag module (curtain or seat-mounted) × 1 — Use OEM Kia specification - varies by location
• Trim panel clips (if damaged) × 5 — Various Kia trim clips
• Airbag connector retaining clips × 1 — Inspect and replace if damaged

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition OFF and remove key from vehicle completely
3. Disconnect negative battery terminal and secure cable away from battery post
4. Disconnect positive battery terminal for complete isolation
5. Wait MINIMUM 3 MINUTES for SRS backup capacitor to discharge - set timer and do not proceed early
6. Document any existing airbag system fault codes with OBD-II scan tool before beginning work
7. Identify exact location of side airbag to be replaced (A-pillar/B-pillar curtain airbag or seat-mounted thorax airbag)
8. Ensure replacement airbag module matches OEM part number exactly - verify visually before installation

Procedure

1. 1

   Remove interior trim panels for access
   For curtain airbag: Remove A-pillar trim by carefully pulling bottom away from pillar, then lifting upward to disengage upper clips. Remove B-pillar upper trim cover by releasing clips at top and bottom. For seat-mounted airbag: carefully pry seat side trim panel away from seat frame using trim removal tools, working from bottom upward. Disconnect any electrical connectors for switches or sensors in removed panels.
2. 2

   Access airbag module mounting location
   For curtain airbag: Remove headliner edge trim along roof rail by releasing retaining clips. Carefully pull headliner down approximately 150mm to expose curtain airbag mounting brackets along roof rail. For seat-mounted airbag: Remove seat trim panel completely to expose side airbag module mounted to seat frame outboard side. Identify mounting bolts and electrical connector.
3. 3

   Disconnect airbag electrical connector
   Locate the yellow SRS connector (curtain airbag connector at A-pillar or seat airbag connector at seat base). Slide the red/yellow safety lock tab to unlock position. Gently press connector release tab and pull connector halves straight apart - DO NOT twist or bend connector. Visually inspect connector pins for damage or corrosion. Secure disconnected vehicle-side connector away from work area.
   ⚠️Ensure 3 minutes have elapsed since battery disconnect. Never force connectors - deployment could occur.
4. 4

   Remove airbag module mounting fasteners
   For curtain airbag: Locate mounting bolts (typically 3-5 bolts) along roof rail securing airbag module brackets. Use appropriate Torx bit to remove Side Airbag Module Bolts. For seat-mounted airbag: Remove mounting bolts securing module to seat frame using Torx bit. Support airbag module weight while removing final fastener. Keep all original fasteners for comparison with replacement hardware.

5. 5

   Remove old airbag module
   For curtain airbag: Carefully guide airbag module downward and out from between headliner and roof structure, feeding electrical connector through any grommets. Module will be long and folded. For seat-mounted airbag: Lift module straight away from seat frame. Immediately place removed airbag module deployment-side UP on clean surface at least 3 meters away from vehicle. Never place face-down or in trunk/enclosed space.
   ⚠️Treat removed airbag as live explosive. Place deployment surface UP, away from people and work area.
6. 6

   Inspect mounting area and hardware
   Thoroughly inspect mounting brackets for cracks, deformation, or corrosion. Check all threaded mounting holes for damage - chase threads if necessary but do not use worn threads. Verify replacement airbag module includes correct mounting hardware. Compare new mounting bolts to originals to ensure proper length and thread pitch. Inspect electrical connector grommet and routing path for damage.
7. 7

   Position new airbag module
   Remove new airbag from packaging only when ready to install - do not leave exposed. For curtain airbag: Route electrical connector through grommet first, then carefully guide folded airbag module into position between roof structure and headliner, ensuring it follows original routing path exactly. For seat-mounted airbag: Orient module with connector facing correct direction and align mounting holes with seat frame brackets. Ensure no wiring is pinched or stressed.
   ⚠Ground yourself before touching new module. Do not touch connector pins. Avoid any impact to module.
8. 8

   Install airbag module mounting bolts
   Hand-start all Side Airbag Module Bolts to ensure proper thread engagement before tightening any fastener. Verify airbag module is seated correctly against mounting surface with no gaps. Tighten mounting bolts to specification using torque wrench in cross-pattern sequence (if multiple bolts). Verify module is secure and does not move when gently pulled.

9. 9

   Reconnect airbag electrical connector
   Inspect both connector halves for debris, moisture, or damaged pins - do not proceed if any damage found. Align connector halves and press together firmly until positive click is heard/felt. Slide safety lock tab to locked position - verify it fully engages and cannot be easily moved. Gently tug on connector to verify secure connection. Ensure connector is positioned in correct routing clip/bracket to prevent strain on wiring.
10. 10

    Verify airbag installation clearances
    For curtain airbag: Ensure airbag module does not interfere with headliner, sun visors, grab handles, or coat hooks throughout deployment zone. Check that headliner can return to normal position without compressing airbag. For seat-mounted airbag: Verify module does not contact seat adjustment mechanisms and has clear deployment path outboard. Ensure no objects or trim pieces obstruct deployment zone.
11. 11

    Reinstall interior trim panels
    Carefully reposition headliner (curtain airbag) or seat trim (seat airbag) to original position. Reinstall all trim panels in reverse order of removal, ensuring all clips engage properly and panels are flush. For curtain airbag: Install B-pillar and A-pillar trim covers, verifying clips engage with audible click. For seat airbag: Snap seat side trim panel into position. Do not force trim - misalignment may indicate airbag module interference.
12. 12

    Reconnect vehicle battery
    Reconnect positive battery terminal first, then negative terminal. Tighten terminal bolts to Ground Bolt specification if applicable. Ensure terminals are clean and make solid connection. Do not turn ignition ON yet - wait for next step.

    System initialization and verification
    Move all persons away from airbag deployment zones. Turn ignition to ON position (do not start engine). Observe SRS warning light on instrument cluster - it should illuminate for approximately 6 seconds then extinguish. If light stays on, flashes abnormally, or does not illuminate, DO NOT drive vehicle. Connect OBD-II scan tool and access SRS module. Clear any stored fault codes from previous fault condition. Perform SRS system self-test through scan tool if available. Verify no active fault codes present.
    ⚠️If SRS warning light does not extinguish or new codes are present, system is NOT safe. Professional diagnosis required immediately.

Reassembly

1. Verify all trim panels are fully seated and all clips engaged properly
2. Confirm no tools or parts remain in vehicle interior or work area
3. Test all switches, handles, and features in areas where trim was removed to ensure proper operation
4. If SRS light illuminates during verification, stop and seek professional diagnosis - do not drive vehicle

Verification

• SRS warning light illuminates for 6 seconds at ignition ON, then extinguishes completely
• OBD-II scan tool shows no active or pending SRS fault codes
• All interior trim panels properly installed with no gaps or loose clips
• Gentle tug test on airbag electrical connector confirms secure connection with safety lock engaged
• Visual inspection confirms airbag deployment zone is clear of obstructions
• If available, dealer-level diagnostic system confirms SRS module recognizes new airbag and system passes self-test
• CRITICAL: Consider professional final inspection if this is your first airbag replacement - improper installation can fail to protect occupants in crash
