Airbag control unit with part number 8200277317

What does the airbag control unit 8200277317 do?

The airbag control unit 8200277317 is the central control unit of the restraint system (SRS) in Renault and evaluates the crash sensors. In an accident it decides within milliseconds which airbags and seatbelt pretensioners are to trigger, and it reports faults via the warning light. After an accident it also stores crash data and locks itself.

Monitoring runs in the background while you drive. The unit checks connections and sensor values without you noticing anything, until a fault occurs.

Why does the control unit 8200277317 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Aged components, cold solder joints, moisture and corrosion, as well as voltage spikes, also play a part.

So the fact that no airbag has deployed does not mean that nothing was stored. The unit creates the data as soon as it classifies an event as an accident.

The other causes tend to develop gradually. Electronic components age, solder joints can be cold, and moisture attacks plug connections. A weak battery or jump-starting can also cause voltage spikes that damage the unit.

How can you tell that the 8200277317 is defective?

The clearest sign is the airbag warning light in the instrument cluster, which lights up constantly or intermittently. Fault messages accompany it, the diagnostic tool does not find the control unit, or the fault memory cannot be cleared, and in an emergency the airbags and seatbelt pretensioners may fail to trigger.

• airbag warning light lights up constantly or intermittently
• fault message in the instrument cluster
• the diagnostic tool cannot establish a connection to the control unit
• the fault memory cannot be cleared

A connection problem at the diagnostic tool does not necessarily lie in the control unit itself.

First compare the number on the label of the removed unit with this page. This only confirms that you have the correct unit in front of you. Also have the fault memory read out before removal, because only this log shows whether the control unit is defective or a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 0 285 001 157, 0 285 001 403, 285001155, 7700426752b, 7700428310, 8200 375 763.

How does the repair of the 8200277317 work?

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

Airbag24 checks the unit on the test bench, repairs defective components, erases stored crash data and carries out a function test. Processing at Airbag24 usually takes 3–4 working days; afterwards Airbag24 returns your own unit 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 8200277317 get to Airbag24?

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