Airbag control unit with part number 9800099180

What does the airbag control unit 9800099180 do?

As the central control unit of the restraint system (SRS) for Peugeot, the airbag control unit 9800099180 works. It processes the signals from the crash sensors, decides in an emergency on airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

The decision is made within fractions of a second. Detected faults are reported by the unit via the airbag warning light that you see in the instrument cluster.

Why does the control unit 9800099180 fail?

With the 9800099180, crash data is the most common cause: it remains stored in the unit after an accident, even if no airbag has been triggered, and a normal diagnostic tool cannot erase it. Other causes include ageing electronic components, moisture and corrosion on plug connections, cold solder joints, and voltage spikes such as those arising from a weak battery or a jump start.

The crash data belong to the control unit itself and cannot be removed with a normal diagnostic tool.

The other causes act gradually on the electronics. Components age, plug contacts are attacked by damp and rust, and solder joints are another weak point. Voltage spikes arise when the battery is weak or when a jump start is used.

How can you tell that the 9800099180 is defective?

On the 9800099180, a defect shows up as an airbag warning light that is on constantly or intermittently, as a fault message in the instrument cluster, as the diagnostic tool being unable to connect to the control unit, and as a fault memory that cannot be cleared.

• Airbag warning light in the instrument cluster is on constantly or intermittently
• Fault message in the instrument cluster
