Description
Product Overview
This Airbag Control Unit (SRS Module) fits Citroën C3 Picasso and carries part numbers 9677253480 and 9803834980. The unit was removed from a donor vehicle and tested to be fully functional, offering a cost-effective solution for professional mechanics and experienced DIY car owners.
Function
The airbag control unit monitors crash sensors, seatbelt pretensioners and other inputs to determine airbag deployment during an impact. It also stores diagnostic fault codes and communicates with the vehicle’s onboard systems to trigger warning indicators when necessary.
Compatibility & Fitment
Designed for Citroën C3 Picasso models on PSA Group platforms that use the listed part numbers. This unit is commonly searched by OEM numbers 9677253480 and 9803834980. Always verify your vehicle VIN and existing module numbers prior to purchase to ensure correct compatibility.
Installation Notes
Replacement should be performed by a qualified technician or an experienced DIYer. Typical steps include disconnecting the negative battery terminal and waiting at least 2 minutes to allow residual power to dissipate, locating and removing the original module (commonly under the dashboard or centre console), fitting the replacement unit, and performing any required coding or system checks. Incorrect installation can lead to SRS malfunction; ensure connectors are clean and secure.
Failure Modes & Lifespan
Airbag control units have no routine service interval. Failures usually follow a collision (when the module records crash data) but can also result from water ingress, corrosion, electrical surges, or damaged connectors. If the module has not been physically damaged in a crash, it may remain serviceable even when removed from a vehicle.
