Function
The curtain/roof airbag deploys from the roof rail in side-impact events or rollovers to reduce head injuries by creating a cushioning barrier between the occupant and the vehicle structure or external object. It is an integral part of the SRS (Supplemental Restraint System) and works together with seat belts and other airbags to improve occupant protection.
Replacement Procedure
Replacement should be performed by a trained technician or an experienced DIY mechanic following manufacturer procedures. Typical steps include:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
- Carefully remove interior trim panels and headliner clips to access the roof rail — use suitable trim tools to avoid damage.
- Unplug the airbag electrical connector and remove mounting fasteners securing the airbag module.
- Install the new airbag in the correct orientation, torque fasteners to manufacturer specification, and reconnect the electrical connector ensuring secure locking.
- Reinstall trim components and reconnect the battery. Clear SRS fault codes with an appropriate diagnostic tool and confirm the airbag system reports no faults.
Estimated replacement time varies with trim level but typically ranges from 30 to 90 minutes in a workshop environment.
Installation Recommendations
- Always disconnect the battery before starting work and adhere to Citroën safety procedures.
- Handle the airbag module carefully; store with the trim side up and avoid impact, heat sources, or static discharge.
- Use correct trim tools to prevent damage to headliner and clips. Replace any damaged fasteners or clips during reassembly.
- After installation, perform a full SRS system check and clear any fault codes with compatible diagnostic equipment.
Why This Part Fails Most Often
- Deployment During Collision: The most common reason for replacement is deployment following a crash.
- Physical Damage: Damage from improper repairs, water ingress from roof leaks, or interior work can compromise the unit or connectors.
- Electrical Faults: Corroded or loose connectors and wiring faults in the SRS circuit can trigger warning lights and require module replacement.
- Age-Related Deterioration: Although airbags have long service lives, exposure to moisture or contaminants can shorten functional lifespan.
