Description
Airbag control unit for PEUGEOT 206 and 206+. Fully functional.
This airbag (SRS) control unit is a direct-fit replacement for Peugeot 206 and 206+ vehicles where the listed product codes match. The unit monitors crash sensors and seatbelt pretensioners, stores fault codes and triggers the deployment sequence in the event of an impact. It is ideal for professional workshops and experienced DIY mechanics looking for a reliable airbag module that restores SRS functionality and clears related fault indicators when correctly installed and configured.
Technical Information
- Manufacturer: Stellantis (Citroén/Peugeot)
- Model: Peugeot 206, Peugeot 206+
- Product Codes: 9660349980, 602327300
- Additional Numbers: 6545GV, 6545T4, 6545GT
Function
The airbag control unit (SRS ECU) centrally processes inputs from accelerometers, impact sensors and occupant detection systems. In the event of a crash it commands airbag deployment and seatbelt pretensioners, logs crash events and illuminates the SRS warning lamp if faults are detected. Proper operation is essential for occupant safety and for passing SRS system self-checks.
Replacement Procedure
- Safety First: Before any work, disconnect the vehicle battery and wait at least 10 minutes (or follow manufacturer recommendations) to allow residual system charge to dissipate.
- Access: Remove the necessary trim and mounting fasteners to reach the unit. The SRS control module is typically mounted centrally in the vehicle; access location can vary by specification.
- Disconnect: Carefully unplug all connectors. Avoid pulling on wiring — release connector locks first.
- Install: Fit the replacement unit, secure mounting fasteners and reconnect all connectors firmly.
- Commissioning: After mechanical installation, clear SRS fault codes and perform a full system scan with a compatible diagnostic tool. If the unit is paired to the original vehicle, cloning or reinitialization may be required (see recommendations below).
- Final Check: Reconnect the battery, confirm the SRS warning lamp behaviour and perform a diagnostic confirmation test.
Installation Recommendations
Work Should Be Performed By A Competent Technician Or Experienced DIYer With Appropriate Tools.
- Always isolate the battery and follow the vehicle manufacturer’s safety procedures when working on SRS components.
- Use an OEM-capable diagnostic tool to read and clear fault codes and to verify system readiness after installation.
- If the replacement unit is used or originates from another vehicle, it may require data cloning or coding so that airbag sensors and associated modules operate correctly together. Improper coding can prevent the system from arming or may leave the SRS warning light on.
- Do not attempt to repair damaged connectors or wiring without proper tools and expertise; faults in the SRS circuit can compromise safety.
Why This Part Fails
Common causes of airbag control unit failure include:
- Electrical Damage: Voltage spikes, improper jump-starting or short circuits can damage internal electronics.
- Physical Damage: Impact in a collision may render the module nonfunctional even if airbags were not deployed.
- Corrosion and Moisture: Water ingress or corrosion at connectors can interrupt signals and cause faults.
- Internal Component Faults: Age-related failures of electronic components or memory corruption after a deployment event.
Notes For Professionals And DIY Mechanics
Matching product codes is essential. The listed numbers (9660349980, 602327300, 6545GV, 6545T4, 6545GT) are commonly used to identify compatible SRS units for Peugeot 206 and 206+. Use an appropriate diagnostic procedure after installation to ensure the SRS system self-checks correctly and no residual fault codes remain.
