Airbag control unit with part number 8200969859

What does the airbag control unit 8200969859 do?

The airbag control unit 8200969859 is the control unit of the restraint system (SRS) for Renault. It evaluates the signals from the crash sensors, decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light.

If the unit stores crash data after an accident, it then locks itself.

Besides the control unit, the restraint system includes sensors, airbags and seatbelt pretensioners. The control unit connects these components and is the place where their signals are evaluated.

Why does the control unit 8200969859 fail?

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

Airbag24 erases the stored crash data during the repair. All other causes affect the electronics in the unit and its connections: solder joints can go cold, components age, moisture makes contacts corrode, and voltage spikes put stress on the circuit.

Which cause applies in an individual case is only shown by a diagnosis. A look at the fault memory before removal therefore brings clarity.

How can you tell that the 8200969859 is defective?

The clearest sign is the airbag warning light in the instrument cluster: it stays on permanently or lights up intermittently. A fault message in the instrument cluster, a diagnostic tool that cannot connect to the control unit and a fault memory that cannot be cleared may also occur.

As soon as the warning light is on, the system is reporting a fault. In an emergency, airbags and seatbelt pretensioners may then fail to deploy. So take the indicator seriously and have the cause checked.

If the diagnostic tool cannot connect to the control unit or faults remain in the memory, that also points to a problem in the system.

Compare the part number on the label of the removed unit with this page; that way you have the right unit. Also have the fault memory read out beforehand, because only the result shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 608361600E, 7701071459, 8200435339, 8200676895E, 8200727514E, 8200959859.

How does the repair of the 8200969859 work?

First you read out the fault memory and enclose the log. Then you disconnect the battery, only then remove the control unit, create a repair order online and send in the unit well packed.

Airbag24 checks the unit on the test bench, replaces defective components, erases the stored crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days.

Your own unit is then returned to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 8200969859 get to Airbag24?

You send the control unit in as a parcel or book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.

Put the printed repair order into the parcel and pack the unit so that it is protected against shocks.
