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.

Function

Side pyrotechnic airbag mounted in the seatside bolster that inflates within milliseconds during a qualifying side impact to reduce injury to the torso and pelvic area. The module contains a gas generator and fabric airbag; it Is a one‑time deployment safety device that must be replaced if deployed or if the SRS system flags a fault specific to the module.

Installation Recommendations

• Disconnect Battery And Wait: Always disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge before starting work.
• Access And Removal: Remove the seat trim and necessary trim panels to reach the airbag module. Support the seat if removal is required. Unscrew the retaining fasteners, unplug the airbag electrical connector (observe any locking clips) and remove the module carefully — do not expose connectors to moisture or contaminate the pyrotechnic connector.
• Replacement And Reassembly: Fit the new airbag module using the original mounting points and torque values where available. Reconnect the airbag connector securely and reinstall trim panels and seat to manufacturer specifications.
• Diagnostics And Reset: After installation, clear SRS fault codes and run a complete SRS system test using an appropriate diagnostic tool. It Is Recommended That Reset And Final Checks Be Performed By A Qualified Technician With Proper Diagnostic Equipment (Official PSA Tools Where Available).
• Safety Precautions: Handle The Module With Care. Do Not Attempt To Test The Pyrotechnic Generator With Unauthorized Equipment. Follow Manufacturer Procedures To Avoid Accidental Deployment Or Damage.

Common Failure Causes

• Deployment In A Previous Collision: The Most Frequent Reason For Replacement Is Prior Deployment During An Accident.
• Connector Or Wiring Damage: Wiring Harness Damage After Collision Or During Seat Removal Can Cause SRS Faults.
• Corrosion Or Water Ingress: Moisture Reaching Connectors Or Seat Internals Can Create Electrical Faults.
• Mechanical Damage: Physical Damage To The Seat Structure Or Airbag Mounting Can Render The Unit Unusable.
• Stored SRS Fault Codes: Sensor Or Control Module Faults Related To The Module May Require Replacement When Diagnostics Identify A Defective Unit.

There Is No Scheduled Service Interval For Airbags; Replace The Module If It Has Deployed, Been Damaged, Or If Diagnostics Indicate A Fault Specific To The Unit. Use The Vehicle’s Service Manual For Detailed Removal, Torque Values And Safety Instructions.
