Description
Airbag control unit for Peugeot 206 and 206+. Fully functional.
Product Overview
This airbag control unit (SRS control module / airbag ECU) is a direct-fit electronic replacement for Peugeot 206 and 206+ models. It is a critical safety component that monitors crash sensors and deploys airbags and seatbelt pretensioners in the event of an impact. Supplied with original reference numbers, it is suitable for professional workshops and experienced DIY mechanics who maintain or repair Peugeot 206 series vehicles.
Features And Function
- Monitors inputs from impact sensors and determines airbag deployment timing.
- Controls front and side airbag deployment and coordinates with pretensioners.
- Stores fault codes and crash event data accessible via diagnostic tools.
- Compact, vehicle-specific design meeting original equipment specifications.
Replacement Procedure
Replacement of the airbag control unit should be performed by a qualified technician or an experienced DIYer comfortable with SRS systems. Typical steps include:
- Disconnect the vehicle battery and wait at least 10 minutes to allow residual power to dissipate before touching SRS components.
- Remove any trim or seat components necessary to access the control unit mounting location.
- Unplug electrical connectors carefully, inspect for corrosion or damage, and remove mounting fasteners.
- Install the replacement unit, secure fasteners to the correct torque, and reconnect clean connectors.
- Carry out a full SRS system scan with a compatible diagnostic tool and clear any stored fault codes. Confirm that the airbag warning lamp goes out and no persistent faults remain.
Installation Recommendations
- Always disconnect the negative battery terminal and wait a minimum of 10 minutes before starting work on the airbag system.
- Use proper tools and avoid static discharge near the unit and airbag modules.
- Check connector pins and wiring harness for corrosion or damage and repair before fitting the new unit.
- After installation, perform a complete diagnostic check. Resetting or clearing codes without addressing root causes is not sufficient.
- If unsure about procedures or if the vehicle shows residual faults after replacement, seek service from a workshop with experience in Peugeot SRS systems.

Why This Part Most Often Fails
- Deployment During Accident: The most common reason for replacement is airbag deployment in a collision, which renders the unit non-serviceable.
- Water Ingress And Corrosion: Moisture entering the housing or connectors can cause internal faults or loss of communication with sensors.
- Electrical Surges Or Short Circuits: Wiring faults, poor grounding, or previous repair errors can damage internal electronics.
- Connector Damage Or Mechanical Stress: Broken pins, loose connectors, or physical damage from improper removal/installation.
Suitable For
This unit is designed for Peugeot 206 and Peugeot 206+ platforms. Confirm fitment by matching the listed product codes with the vehicle’s existing module before installation.
Notes For Mechanics And DIYers
- Keep the replacement unit in its anti-static packaging until installation.
- Record any diagnostic trouble codes before replacing the unit to aid fault tracing if problems persist after installation.
- Do not attempt to repair a control unit that has been exposed to crash deployment; replacement is the recommended course.
