Description
Driver airbag for the steering wheel for CITROËN C4 PICASSO and GRAND PICASSO up to 2011. Color HZD – Black Mistral.
Product Overview
This original-fit steering wheel driver airbag is designed for Citroën C4 Picasso and Grand Picasso models built up to 2011. It is a direct-replacement safety component intended for professional workshops and experienced DIYers who maintain PSA group vehicles. Often searched by OE code 96866504ZD or part number 4112PC — using the product code speeds up finding the exact match for the vehicle.
Function and Benefits
The driver airbag is a core part of the Supplemental Restraint System (SRS). In the event of a collision, the module inflates milliseconds after impact to reduce the risk of serious injury to the driver by cushioning and limiting forward movement. This unit is manufactured to fit the original steering wheel geometry and trim (Black Mistral finish), ensuring correct deployment trajectory and aesthetic match.
How It Fails And Service Life
Airbags do not have a fixed service interval. Replacement is required after deployment in a crash or when the SRS system reports a persistent fault. Common causes of failure or replacement include crash deployment, electrical faults from damaged wiring or connectors, corrosion in contact points, and physical damage to the module. Environmental contamination (moisture, salts) or improper handling during previous repairs can also cause faults or loss of functionality.
Replacement Procedure (Summary)
Only qualified persons should perform SRS work. General replacement steps: disconnect the vehicle battery and wait the manufacturer-recommended time for residual charge to dissipate; remove steering wheel trim and airbag retaining fasteners; carefully disconnect airbag electrical connectors (note locking tabs); remove old module and mount the replacement ensuring correct orientation; reconnect connectors and secure fasteners to manufacturer torque specifications; clear SRS codes and verify system status with a diagnostic tool. Always follow vehicle manufacturer instructions and safety precautions when handling and fitting airbag modules.
Installation Recommendations
- Disconnect the negative battery terminal and wait at least the time specified by Citroën before starting work to avoid accidental deployment.
- Use the correct tools to avoid damaging connector locks, airbag housing, or steering wheel trim.
- After installation, perform a full SRS system check with a compatible diagnostic tool and erase any saved fault codes only when the underlying issue has been resolved.
- Observe ESD and handling precautions; store and transport the airbag facing upward to reduce risk in case of accidental activation.
Why This Part Most Often Fails
The most frequent reason for replacement is crash deployment. Other common issues are electrical faults due to connector corrosion or damaged wiring in the steering column, improper previous repairs, or moisture ingress. In many cases the airbag itself is intact but the SRS circuit reports faults from the clockspring or connectors, which still necessitates replacement or repair of the affected components.

Notes For Mechanics And DIYers
Search by OE code (96866504ZD) when looking for compatibility. Airbag replacement is a safety-critical job: if you are not fully confident in SRS procedures and diagnostic checks, have the replacement performed or validated by a workshop experienced with Citroën/Peugeot vehicles.
