Technical Information

• Manufacturer: Citroën (Stellantis)
• Model: Citroën C4 Picasso, Grand Picasso
• Product Codes: 9688582280, 8216XL
• Additional Numbers: 968582280

Function

The front passenger airbag is a primary passive safety component that deploys in moderate to severe frontal impacts to reduce injury risk to the occupant. The module contains a single pyrotechnic inflator (squib) and the cushion assembly. On activation the inflator rapidly generates gas to inflate the cushion, controlling occupant deceleration and limiting contact with hard interior surfaces.

Replacement Procedure (Overview)

Only undertake replacement if you have appropriate training and tools. Typical steps for removal and installation:

• Disconnect The Battery: Always disconnect the negative battery terminal and wait the manufacturer recommended time (usually several minutes) to ensure the SRS capacitors discharge.
• Access The Module: Remove trim pieces or the glovebox to reach the passenger airbag fasteners. Keep fasteners and trim organized for reassembly.
• Disconnect Connectors: Carefully unplug the airbag electrical connector(s). Avoid pulling on wires; release any locking tabs first.
• Remove The Module: Unscrew the retaining bolts and extract the airbag module from the dashboard cavity.
• Install New Module: Position the replacement module, tighten fasteners to the manufacturer torque if specified, and reconnect the electrical connector securely.
• System Check: After reassembly reconnect the battery and use an SRS-capable diagnostic tool to clear faults and confirm system status. Follow the vehicle manufacturer’s procedures for final checks.

Installation Recommendations

• Observe All Safety Precautions: Always disconnect the battery before beginning work and follow the vehicle manufacturer’s service manual step-by-step instructions.
• Use Proper Tools: Use the correct screwdrivers, torque tools, and an SRS-compatible diagnostic interface to verify system integrity after replacement.
• Handle With Care: Do not strike, heat, or disassemble the airbag module or inflator. Store the module with the airbag cushion facing upward and away from heat sources.
• Professional Verification Recommended For Code Clearing: Use an SRS diagnostic tool to confirm no residual faults remain; if inexperienced, have a qualified technician perform the final checks.

Most Common Failure Causes

• Previous Deployment: Airbags that have deployed in a collision must be replaced; they cannot be reused.
• Connector Or Wiring Damage: Chafed wiring, corroded connectors, or poor electrical contacts can cause SRS fault codes or prevent deployment.
• Water Ingress Or Interior Damage: Moisture from leaks or flooding can compromise the inflator or connector integrity.
• Age And Environmental Exposure: Over long service life exposure to heat, humidity, or vibration can lead to component degradation.
• Manufacturing Defects Or Recalls: In rare cases certain inflator batches may be subject to technical service actions; always compare part numbers before installation.

Search By Part Number: When hunting for the correct unit, use references 9688582280 and 8216XL to speed up identification. Match connector type and mounting points before installation to ensure correct fit and function.

• Other Numbers: 8216PG

Function

The unit is a side (seat-mounted) airbag with a pyrotechnic inflator. Its primary function is to deploy in milliseconds during a qualifying side impact to reduce thoracic and pelvic injuries by creating a controlled cushion between the occupant and the intruding structure.

Installation Recommendations

Always follow manufacturer safety procedures. Before starting work, disconnect the vehicle battery and wait the time specified by the vehicle manufacturer (commonly around 10 minutes) to allow SRS capacitors to discharge. Remove seat trim and upholstery carefully to access the airbag module; avoid cutting or damaging wiring or sensor leads. Disconnect the airbag connector using the locking mechanism—do not force pins or use excessive leverage. Position the airbag with the cover facing away from you when removing and store it with the inflated face up and away from heat sources. When fitting the replacement, ensure connectors are fully engaged and locked, seat fasteners are tightened to the vehicle manufacturer’s torque specifications, and then perform a full SRS system check and clear any crash codes with a diagnostic tool. Final verification should confirm the SRS warning lamp extinguishes after the system check.

Most Common Failure Causes

Airbags are typically replaced after deployment in a collision. Other common causes for replacement or faults include damaged wiring or connectors under the seat (often due to seat rail movement or corrosion), impact-related damage to the seat structure, and water ingress or corrosion at connector points. Faults may also arise from prior improper removal or damaged locking tabs. Regular inspection after accidents and correct handling during seat removal reduce the risk of damage during service.
