Function and Application
The roof (curtain) airbag protects the head area during side collisions and rollovers, reducing the risk of severe head injuries. It is mounted along the roof rail and deploys downwards to cover the side window area. This specific unit is for the left (driver) side of Citroën C4 Picasso and Grand Picasso vehicles.
Symptoms Indicating Replacement
- SRS/airbag warning lamp illuminated after a collision or due to wiring faults.
- Visible damage to the headliner, roof rail, or trim following an impact.
- Connector or wiring corrosion from moisture ingress.
Common Causes Of Failure
- Deployment in a previous collision — airbags are single-use and must be replaced after inflation.
- Electrical faults caused by damaged connectors, chafed wiring, or corrosion, often due to water ingress.
- Incorrect previous repairs or improper handling during interior work that can damage the unit or its connector.
Installation Recommendations
Always follow safety procedures when working with SRS components. General replacement steps used by professional technicians:
- Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
- Carefully remove the A-pillar trim and roof-lining side trim to access the airbag module and its fasteners.
- Unbolt the retaining screws or clips securing the airbag and carefully disconnect the SRS connector (usually marked with a yellow plug).
- Fit the new airbag in the correct orientation, secure all fasteners to the manufacturer’s torque specifications, and reconnect the SRS connector.
- Refit trims, reconnect the battery, and verify the SRS system with a diagnostic tool to clear fault codes and confirm proper operation of the airbag circuit.
Use appropriate trim tools to avoid damaging interior parts. If the vehicle displays persistent SRS faults after replacement, inspect wiring and connectors in the roof rail and B-pillar harnesses for damage or corrosion.
