Function
The roof-side (curtain) airbag is part of the vehicle’s SRS (Supplemental Restraint System). It deploys from the headliner area along the side of the passenger compartment to protect the head and upper torso in side impacts and rollovers. Correct positioning and secure attachment are essential for proper deployment trajectories and occupant protection.

Installation Recommendations
- Always Disconnect The Battery Before Work: Isolate the negative terminal and wait at least 10 minutes (or follow manufacturer-recommended waiting time) to allow the SRS backup power to discharge.
- Remove Interior Trim Carefully: Detach headliner and trim panels without damaging clips or wiring harnesses. Keep mounting hardware for reinstallation or replace with OEM-specified fasteners.
- Handle The Airbag With Care: Do not apply impact, heat, or electrical current to the inflator assembly. Keep the airbag module facing away from personnel when handling.
- Secure Mechanical Fixing Points: Mount the airbag to original anchor points and torque fasteners to manufacturer specifications.
- Reconnect And Verify SRS: After installation, reconnect the battery and perform a system check with an SRS-capable diagnostic tool to confirm no fault codes remain and the airbag indicator operates correctly.
How Replacement Is Performed
Typical replacement steps: disconnect battery and wait; remove interior trim and headliner panels to access the roof rail; unbolt and disconnect the old airbag connector; install the new airbag in the same orientation, secure fasteners, and reconnect the SRS connector; reinstall trim and headliner; perform SRS system scan and clear codes if applicable. Use proper service manual procedures and tooling for safe removal and refit.
Most Common Failure Reasons
- Deployment In A Collision: Airbags Are Single-Use—After Deployment The Module Must Be Replaced.
- Water Ingress Or Sunroof/Seal Leaks: Moisture Can Cause Connector Corrosion Or Damage To The Inflator Circuitry.
- Electrical Faults Or Damaged Wiring: Chafed Or Disconnected Wires Prevent Proper Signal From The SRS Control Unit.
- Previous Poor Repairs Or Incorrect Handling: Improper Removal/Reinstallation Or Damaged Mounting Points Can Compromise Function.
Additional Notes
This airbag is a critical safety component. Work Should Be Carried Out By Trained Personnel Or Experienced Mechanics Familiar With SRS Procedures. Always Follow The Manufacturer’s Service Manual For Torque Values, Wiring Diagrams And Safety Precautions.
