Knee Airbag For Citroën C4 Grand Picasso
Color HZD – Black Mistral
This knee airbag is a direct-fit safety component intended for Citroën C4 Grand Picasso vehicles. Ideal for professional workshops and experienced DIY mechanics, the part is commonly searched by its product codes (96600568ZD, 8216NW). Replacing a faulty knee airbag restores proper occupant protection under the dash and clears SRS faults that can prevent vehicle operation or inspection approval.
Technical Information
- Manufacturer: Stellantis / Citroën
- Model: Citroën C4 Grand Picasso (C4 Picasso variants)
- Product Codes: 96600568ZD, 8216NW
- Additional Numbers: 96600568DZ (alternate listing)
Function And Application
The knee airbag cushions and controls lower-body movement of the front occupant in a frontal impact, reducing leg and knee injuries. It is installed in the lower instrument panel area (front occupant compartment). Correct fitment and secure electrical connections are essential for the SRS system to recognize the module and for proper deployment performance.
Replacement Procedure (Overview)
Basic replacement steps for trained technicians or confident DIYers:
- Disconnect the negative battery terminal and wait the manufacturer-recommended time to discharge residual system energy.
- Remove lower dash trim and any panels obstructing access to the knee airbag module.
- Unplug the airbag electrical connector(s) using appropriate tools and take anti-static precautions.
- Unbolt the airbag module from its mounting points and remove it carefully.
- Fit the new module, secure bolts to the manufacturer torque specification, and reconnect the electrical connector(s).
- Reinstall trim panels, reconnect the battery, and clear SRS fault codes with a suitable diagnostic tool. Verify SRS lamp behavior and system readiness.
Installation Recommendations
- Always Disconnect The Battery Before Work: Prevents accidental deployment and electronic damage.
- Follow Manufacturer Torque Values And Mounting Order: Ensures correct alignment and deployment characteristics.
- Use A Diagnostic Tool After Installation: Clear SRS fault codes and confirm system status. If SRS warnings persist, inspect wiring and connectors.
- Handle The Airbag Module Carefully: Avoid impacts, static discharge, or placing the module face-down on hard surfaces.
Why The Part Fails Most Often
Knee airbags are robust and typically do not fail under normal service life. Common causes of replacement include:
- Crash Deployment: Airbags are single-use; any deployment requires replacement of the deployed module.
- Connector Or Wiring Damage: Corrosion, loose pins, or damage during other repairs can generate SRS faults.
- Moisture Ingress: Water intrusion behind the dash can corrode connectors and cause electrical failure.
- Previous Improper Removal Or Repair: Mishandling during prior service can deform mounting or damage harnesses.
Note: There is no routine mileage-based replacement interval for airbags; replace when fault codes indicate a malfunction or after deployment.
