Airbag control unit with part number 9803380680

What does the airbag control unit 9803380680 do?

The airbag control unit 9803380680 coordinates the SRS restraint system of Peugeot. It evaluates the crash sensors, decides in an accident within milliseconds on the triggering of airbags and seatbelt pretensioners, and reports faults via the airbag warning light. After an accident it stores crash data and locks itself.

Monitoring runs without interruption during operation. Wiring, sensors and trigger elements are checked continuously, and deviations end up in the fault memory.

The fault memory is therefore the first source of information when a defect needs to be clarified.

Why does the control unit 9803380680 fail?

The most common cause is stored crash data after an accident, even if no airbag has deployed. Other causes are ageing electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

After an accident, crash data remain in the unit even if the vehicle continues to run inconspicuously.

The other causes can lie in the electronics and the connections. Ageing components, damp contacts and solder joints that give way over time can cause faults. Voltage spikes, for example from a weak battery or jump-starting, are also possible.

How can you tell that the 9803380680 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, an error message may appear in the instrument cluster, the diagnostic tool may be unable to establish a connection to the control unit, or the fault memory cannot be cleared. In that case, airbags and seatbelt pretensioners may not be able to trigger in an emergency.

• Airbag warning light stays on permanently
• Airbag warning light comes on intermittently
• Error message in the instrument cluster
• No connection to the diagnostic tool
• Fault memory cannot be cleared

The warning light indicates the fault itself. Take the warning seriously and have the vehicle checked rather than ignoring it.

Compare the part number on the label of the removed unit with this page. This only shows whether it is the correct unit. Have the fault memory read out beforehand, because the result alone shows whether the control unit is defective or a plug or cable is the cause.
