Airbag control unit with part number 9674909280

What does the airbag control unit 9674909280 do?

The airbag control unit 9674909280 is the central control unit of the restraint system (SRS) at Peugeot. It evaluates the signals from the crash sensors and decides in an accident within milliseconds which airbags and seatbelt pretensioners fire. After an accident, it stores crash data and locks itself.

While driving, the control unit continuously monitors the sensors, the firing circuits and the power supply. If it detects a fault, it reports this via the airbag warning light in the instrument cluster.

The crash data are measured values from the accident. They remain in the memory even if no airbag has deployed.

Why does the control unit 9674909280 fail?

The most common cause with this control unit 9674909280 is crash data that remained stored after an accident, even if no airbag has deployed. Other causes include ageing components, moisture at plug connections and voltage spikes.

A normal diagnostic tool cannot erase this crash data, so simply reading it out does not help. The other causes at a glance:

• Electronics that age over the years
• Solder joints on the circuit board
• Corrosion at plug connections
• Voltage spikes when starting or from a jump start

How can you tell that the 9674909280 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears, the diagnostic tool does not find the control unit 9674909280, or the fault memory cannot be cleared. In this case, airbags and seatbelt pretensioners may fail to deploy in an emergency.

Watch for these signs:

• Warning light on in the instrument cluster, permanently or intermittently
• Error message on the display
• Diagnostic tool cannot reach the control unit
• Fault memory stays stored

The warning light must be taken seriously because it indicates the fault directly. Have the fault memory read out as soon as one of these signs appears.
