Airbag control unit with part number 8201133333

What does the airbag control unit 8201133333 do?

The unit is the control centre of the restraint system (SRS) for Renault. It processes what the crash sensors report, determines within milliseconds which airbags and seatbelt pretensioners trigger, and monitors the entire network continuously. It communicates faults via the airbag warning light.

During driving, monitoring runs in the background without interruption.

After an accident the control unit writes crash data and then locks out.

Why does the control unit 8201133333 fail?

The most common cause is stored crash data from an accident, even if no airbag has fired. A normal diagnostic tool does not erase it; Airbag24 removes it during the repair. Further causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

Crash data arises from the event itself and does not automatically mean that a component has been destroyed. The other causes tend to act over a long time, because ageing and moisture attack contacts and solder joints.

How can you tell that the 8201133333 is defective?

A defect shows itself as the airbag warning light in the instrument cluster or as a fault message in it. A diagnostic tool without a connection to the control unit is also one of the signs.

The signs in detail:

• Airbag warning light in the instrument cluster, permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then fail to trigger. Take this seriously, even if the vehicle otherwise runs normally.

Compare the part number of the removed unit with this page to make sure you have the right unit. Have the fault memory read out beforehand, because only its content shows whether the control unit itself or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 2840211503, 8200 656 329, 8200656331, 8201 229 153 A, 8201 475 929, 8201025624.

Then create a repair order online and send in the well-packed unit.

Airbag24 checks the unit on the test bench, repairs defective components and erases the stored crash data. A function test follows at the end, after which your own unit is 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.
