Airbag control unit with part number 9673577480

What does the airbag control unit 9673577480 do?

The airbag control unit 9673577480 is the control unit of the restraint system (SRS) for Peugeot. It processes the signals from the crash sensors, decides in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously. After an accident it stores crash data and locks itself.

The system reports its status via the airbag warning light in the instrument cluster.

The triggering decision depends on the sensor signals that this unit evaluates in bundled form.

Why does the control unit 9673577480 fail?

The most common cause is stored crash data, even if no airbag has triggered; a normal diagnostic tool does not erase it. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump starting.

The crash data remains in the unit after the event. Airbag24 removes it during the repair.

The further causes at a glance:

• wear of the electronics due to age
• solder joints that have stayed cold
• moisture and corrosion on the plugs
• voltage spikes from a weak battery

How can you tell that the 9673577480 is defective?

Typical signs are an airbag warning light in the instrument cluster, an error message there, and a fault memory that cannot be cleared. A diagnostic tool without connection to the control unit also counts. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The warning light is either permanently on or intermittently lit. Both variants are a clear sign that something is wrong in the restraint system.

The diagnostic tool failing to reach the control unit is a further sign. Together these signs form a coherent picture that must be taken seriously.
