Airbag control unit with part number 9676209180

What does the airbag control unit 9676209180 do?

The airbag control unit 9676209180 is the switching centre of the restraint system (SRS) for Citroën. It processes the signals from the crash sensors, decides in an accident whether airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light. After a crash it stores crash data and locks itself.

In the background the unit constantly checks whether sensors and wiring are in order.

Why does the control unit 9676209180 fail?

The most common cause is crash data from an accident, even if no airbag was deployed. Further causes are aged components, solder joints, moisture and corrosion on plug connections, and voltage spikes. A normal diagnostic tool cannot erase the crash data.

In detail, these further causes are possible:

• Aged electronic components
• Cold solder joints
• Moisture and corrosion on plug connections
• Voltage spikes, for example from a weak battery or a jump start

Airbag24 erases the crash data during the repair.

How can you tell that the 9676209180 is defective?

Typical signs are the airbag warning light in the instrument cluster, an error message there, a missing connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared. In an emergency the airbags and seatbelt pretensioners may then not deploy.

• Airbag warning light lights up permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool cannot reach the control unit
• Fault memory cannot be cleared

Have these signs checked promptly.
