Function And Fitment
The seat-mounted driver airbag cushions and protects the torso and pelvis in side impacts and certain collisions. It is mounted inside the left-side driver seat (seatback/cushion area depending on the variant) and integrates with the vehicle SRS (Supplemental Restraint System). This unit is intended for Peugeot 407 models; verify correct part code match before installation. If the original airbag has been deployed, damaged, or triggers an SRS warning light, replacement is required to restore full system functionality.
Recommended Installation
- Disconnect the negative battery terminal and wait at least 10 minutes to allow SRS capacitors to discharge.
- Remove seat trim and covers carefully to avoid tearing cloth/leather and damaging clips.
- Unbolt the airbag module from the seat frame using hand tools; avoid impact tools that can damage the unit.
- Disconnect the airbag electrical connector by releasing locking tabs—do not pull on wires.
- Install the replacement airbag in reverse order. Use manufacturer torque values for seat and airbag fasteners (refer to the workshop manual).
- After installation, reconnect the battery and use an appropriate diagnostic tool to check and clear SRS fault codes. Confirm that the airbag warning lamp behaves normally during key-on self-test.
- Handle and store the airbag with the pad facing upward and avoid exposure to heat sources, sparks or static discharge.
Most Common Failure Causes
- Deployment In A Collision: Airbags are single-use; any deployed airbag must be replaced.
- Electrical Damage Or Corrosion: Moisture ingress, connector corrosion, or damaged wiring can cause SRS faults and loss of function.
- Connector Or Harness Damage During Seat Removal: Rough handling when removing seats or interior trim can damage the airbag connector or wiring.
- Mechanical Damage: Seat impact, excessive wear, or improper repairs can impair module mounting or inflate performance.
- Faults Detected By SRS Control Unit: Sensor or module faults logged by the SRS control unit will illuminate the airbag warning light and necessitate diagnosis and possible replacement.
Replacing the airbag should be performed by qualified technicians or experienced DIYers who follow SRS safety procedures and have access to the vehicle workshop manual and diagnostic equipment. Proper installation ensures reliable operation and passenger protection in the event of an accident.
