Description
Airbag Control Unit Autoliv for Peugeot 407
Product Overview
Airbag Control Unit (SRS Module) manufactured by Autoliv for Peugeot 407 vehicles. This control unit monitors crash sensors and activates the appropriate restraint systems (airbags and seatbelt pretensioners) in the event of a collision. The unit also stores fault codes and crash event data that are used by diagnostic equipment to determine the cause of an airbag system fault.
Key Benefits
- Direct fitment for Peugeot 407 when matched to the correct product code.
- Essential safety component: ensures timely deployment of airbags and pretensioners.
- Contains crash data memory used for post-accident diagnostics and repairs.
- Product codes included to simplify search and compatibility checks.
How It Works
The Airbag Control Unit continuously monitors inputs from accelerometers, impact sensors, and related wiring. When pre-set thresholds are exceeded during an impact, the unit commands inflation of the relevant airbags and activation of seatbelt pretensioners. After a deployment event the unit typically records crash data and fault codes and must be replaced or reprogrammed according to manufacturer procedures.

Installation Recommendations
Only install this unit if the product codes match the required part for the vehicle. Basic replacement steps for experienced technicians or skilled DIYers with appropriate tools:
- Disconnect The Battery: Always disconnect the negative battery terminal and wait at least 10 minutes to allow system capacitors to discharge.
- Access The Unit: Remove trim panels and mounts to reach the SRS module. Keep connectors and wiring free of corrosion and contamination.
- Disconnect Connectors: Release locking tabs carefully to avoid damage to pins and housings.
- Replace The Unit: Remove mounting fasteners, fit the replacement unit in the original orientation and torque fasteners to manufacturer specification.
- After Installation: Reconnect the battery, perform a full system scan and clear stored fault codes using appropriate diagnostic equipment. Verify that all SRS warning indicators behave normally.
Handle The Unit With Care: Do not open, disassemble, or expose the unit to moisture. Avoid impact and static discharge. Follow Peugeot service procedures and safety precautions during removal and installation.
Why This Part Fails
Common Causes Of Faults Or Failure:
- Crash Deployment: Units that have recorded a deployment event typically require replacement because crash data and firing circuits can be affected.
- Water Ingress And Corrosion: Moisture entering the connector area or housing can cause electrical faults or sensor errors.
- Electrical Surges Or Short Circuits: Damage from improper jump-starting, shorting, or wiring faults can degrade internal electronics.
- Connector Damage And Wiring Faults: Bent pins, broken wires, or poor ground connections result in intermittent or permanent faults.
- Age-Related Component Degradation: Over long service life, internal components or solder joints can fail.
Service Life And Replacement Guidance
There Is No Fixed Replacement Interval. Replace The Unit After A Deployment Event Or If The Diagnostic System Shows Non-Repairable Faults. If Fault Codes Persist After Repair Of Related Wiring And Sensors, The SRS Module May Need Replacement.
Suitability For Mechanics And DIYers
This unit is suitable for professional workshops and experienced DIY mechanics who have access to proper diagnostic tools. Correct diagnosis, safe handling, and post-installation scanning are essential to restore full SRS functionality and vehicle safety.
