Description
Overview
Airbag Control Unit for the Citroën C3 Picasso, referenced under product codes 9677253480 and 9803834980. This control unit is a key component of the supplemental restraint system (SRS) and has been removed from a donor vehicle, inspected and tested by specialists; it is confirmed fully functional and ready for installation.
Function And Benefits
The airbag control unit monitors crash sensors and triggers airbag deployment to protect the driver and passengers during an impact. Replacing a faulty unit restores the original behaviour of the airbag system, clears SRS fault codes (after correct installation), and ensures the vehicle meets safety expectations. Supplying a direct fit for Citroën C3 Picasso models listed by the product codes increases the likelihood of plug-and-play compatibility for repair shops and skilled DIYers.
Common Failure Modes And Lifespan
Airbag control units typically fail after deployment in a collision; other causes include electrical faults, water ingress, corrosion of connector pins, or damage from voltage spikes. If the SRS warning light is illuminated, or airbag-related diagnostic trouble codes are stored, the control unit is a prime suspect. Outside of crash events, many units can remain serviceable for the vehicle’s lifetime but should be diagnosed with appropriate tools before replacement.
Installation Guidance
Intended for professional mechanics and experienced DIYers. Basic replacement steps: disconnect the battery and wait the manufacturer-recommended time; remove interior trim panels to access the unit; unplug connectors and unfasten mounting bolts; install the replacement unit, reconnecting all plugs securely; reconnect the battery and perform a diagnostic scan to clear and confirm SRS codes. Due to the critical safety function, calibration or electronic configuration may be required depending on vehicle variant—use diagnostic equipment or consult a qualified technician.
