- Direct Replacement For Seats Of The C4 Picasso II / Grand C4 Picasso
How It Works
The seat side airbag contains a pyrotechnic inflator (squib) that deploys the airbag in the event of a qualifying side impact. Deployment cushions the occupant’s chest and pelvis, reducing the risk of severe injury by absorbing energy and limiting lateral movement. The airbag is triggered by the vehicle’s crash sensors and SRS control unit.
Replacement Procedure (Summary)
Replacement should be performed by a qualified technician or a competent DIYer familiar with SRS systems. Typical steps:
- Park vehicle on level ground and engage parking brake.
- Disconnect the negative battery terminal and follow manufacturer-recommended waiting time before working on the SRS system.
- Remove the seat from the vehicle by unbolting the seat rails and disconnecting any electrical connectors (seatbelt pretensioner, seat heaters, sensors).
- Carefully remove the seat cover and trim to access the airbag module; unbolt the airbag from the seat frame and unplug the squib connector.
- Install the new airbag module, secure bolts to manufacturer torque, reconnect the squib connector and any seat wiring, and refit trim and seat into the vehicle.
- Reconnect battery and clear SRS fault codes using a diagnostic tool; verify SRS warning lamp extinguishes and run a system check.

- Corrosion Or Poor Electrical Contact At The Squib Connector Or Wiring Harness, Often Caused By Moisture Ingress.
- Incorrect Installation Or Pinched Wires During Seat Repairs Leading To Intermittent Or Faulty Circuits.
