Airbag control unit with part number 8200322002

What does the airbag control unit 8200322002 do?

As the control centre of the SRS system of Renault, the airbag control unit 8200322002 works. It checks the messages from the crash sensors and, in an emergency, triggers the appropriate airbags and seatbelt pretensioners within milliseconds. After an accident it stores crash data and locks itself.

The system is monitored continuously during operation. The control unit detects faults in the components, reports them via the airbag warning light and keeps them recorded in the fault memory.

Why does the control unit 8200322002 fail?

Stored crash data is the most common cause in the control unit 8200322002, even if no airbag has triggered. An ordinary diagnostic tool cannot erase it. Other causes include aged electronic components, cold solder joints, moisture and corrosion on plug connections, and voltage spikes.

The crash data stays in the unit even if no airbag has triggered. The other causes result from the age of the component and the on-board voltage, and they occur independently of the accident. They can only be reliably classified by measurement.

How can you tell that the 8200322002 is defective?

A defect in the 8200322002 shows up as the airbag warning light in the instrument cluster lighting up permanently or intermittently, and as an error message in the instrument cluster. The diagnostic tool does not reach the control unit, or the fault memory cannot be cleared. In this state, airbags and seatbelt pretensioners may possibly not trigger in an emergency.

If the warning light is lit, have the fault memory read out so that the location of the fault can be narrowed down.
