Airbag control unit with part number 9634474180

What does the airbag control unit 9634474180 do?

The airbag control unit 9634474180 is the central control unit of the restraint system (SRS) for Peugeot. It evaluates the crash sensors, decides in a crash within milliseconds whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

Faults are reported via the airbag warning light in the instrument cluster. After a crash it stores crash data and locks itself; the lock is lifted only by the repair.

Why does the control unit 9634474180 fail?

The most common cause is stored crash data after an accident, even if no airbag has been triggered; a normal diagnostic tool cannot remove it. Further possible causes are:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes from a weak battery or a jump start

During the repair at Airbag24 the crash data is erased. Which of the other causes is present is clarified only by the examination.

How can you tell that the 9634474180 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

The warning light is the direct indication of a fault in the restraint system. A diagnostic tool without a connection to the unit also points to the problem. In an emergency, airbags and seatbelt pretensioners may possibly not trigger, so please have the system checked promptly.
