Airbag control unit with part number 8200047304

What does the airbag control unit 8200047304 do?

The airbag control unit 8200047304 is the central control unit of the restraint system (SRS) for Renault. It takes in the values of the crash sensors, determines the triggering of airbags and seatbelt pretensioners within milliseconds in an accident, and monitors the system continuously.

Faults appear via the airbag warning light in the instrument cluster. After an accident the unit stores crash data and locks itself.

The system consists of sensors, triggering elements and the control unit, which coordinates everything.

Why does the control unit 8200047304 fail?

The most common cause for the control unit 8200047304 is crash data stored after an accident, even without a triggered airbag. Further causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be removed with an ordinary diagnostic tool. Airbag24 erases it during the repair.

Moisture, corrosion and cold solder joints impair the connections and the electronics over a longer period.

Voltage spikes arise, for example, from a weak battery or a jump start.

How can you tell that the 8200047304 is defective?

A defect on the control unit 8200047304 shows up at the airbag warning light in the instrument cluster, which lights up permanently or intermittently, and at an error message in the instrument cluster. In addition, no connection to the diagnostic tool can be made, and the fault memory cannot be cleared. Then airbags and seatbelt pretensioners may possibly not trigger in an emergency.

Do not ignore the warning light. Even a brief lighting up justifies a check.

Report the fault early to a workshop, or have the fault memory read out promptly, to narrow down the cause.
