Replacement Procedure
General replacement steps for experienced technicians and knowledgeable DIYers:
- Park the vehicle on a level surface, engage parking brake and follow all manufacturer safety precautions.
- Disconnect the negative battery terminal and wait at least 10 minutes (or manufacturer’s recommended time) to allow SRS capacitors to discharge.
- Remove necessary trim, seats or consoles to access the airbag control unit location (refer to vehicle workshop manual for exact location and fastener types).
- Unplug electrical connectors carefully; avoid pulling on wiring. Unbolt the control unit and remove it from the vehicle.
- Fit the replacement unit, secure fasteners to manufacturer guidance, and reconnect all connectors ensuring proper seating and no damaged pins.
- Reconnect the battery. Use an appropriate diagnostic tool to read and clear SRS fault codes, verify sensor inputs and confirm system status. For PSA vehicles, PSA diagnostic tools are recommended to ensure full functionality.
Installation Recommendation
Always follow vehicle manufacturer instructions. Disconnect the battery before starting work and observe electrostatic discharge precautions. After installation, use a diagnostic scanner capable of SRS functions to clear crash data and confirm the airbag warning lamp behavior. If crash data is present, the module will likely need data clearing or replacement depending on the recorded event. For Peugeot/PSA vehicles, service tools such as DiagBox / Lexia / PP2000 are recommended to perform full diagnostics and reset procedures.
Most Common Reasons For Failure
- Vehicle Impact/Crash: The most frequent cause—after deployment the unit often records crash data and may require replacement.
- Water Ingress or Corrosion: Moisture entering the connector or module housing can cause electrical faults.
- Connector Or Wiring Damage: Poor connections, pin corrosion or mechanical damage lead to intermittent or permanent faults.
- Electrical Surges Or Short Circuits: Battery issues, jump-starts or improper electrical work can damage the unit.
- Internal Electronic Faults: Component failure inside the module due to age or manufacturing defects.
