Airbag control unit with part number 8200687759

What does the airbag control unit 8200687759 do?

The airbag control unit 8200687759 is the central control unit of the restraint system (SRS) of Renault. It evaluates the signals from the crash sensors, decides in a crash within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After a crash it stores crash data and locks itself.

As long as all components work properly, the unit goes unnoticed in everyday driving. To do this, it continuously checks the lines to the sensors, the seatbelt pretensioners and the airbags. If it detects a deviation, it records a fault entry and reports the fault via the airbag warning light in the instrument cluster.

Why does the control unit 8200687759 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase them. Airbag24 erases them during the repair. Other causes are aged components, moisture and voltage spikes.

Crash data alone say nothing about the condition of the remaining electronics. The inspection in our workshop shows which assembly is actually affected. The following causes are also possible:

• aged electronic components
• cold solder joints on the circuit boards
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

How can you tell that the 8200687759 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, an error message appears in the instrument cluster, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

A warning light that only flashes at times is no reason for reassurance. It shows that the system has detected a fault, even if the car still drives normally.

As long as the fault persists, airbags and seatbelt pretensioners may fail to deploy in an emergency. A prompt check is therefore advisable.

Compare the part number on the label of the removed unit with this page; this only confirms that it is the correct unit. Also have the fault memory read out beforehand, because 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 603785400, 603785500, 605487700, 8200313338, 8200343319, 8200343319A.

How does the repair of the 8200687759 work?

First you have the fault memory read out and enclose the log, then you disconnect the battery and only then remove the control unit. Afterwards you create a repair order online and send in the well-packed unit. Airbag24 tests it on the test bench, repairs defective components, erases stored crash data and carries out a function test; after that your own unit is sent back.

Processing at Airbag24 usually takes 3–4 working days. This time covers only testing, repairing and checking in-house.

The order of these steps is for your safety during removal and is therefore binding. 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 8200687759 get to Airbag24?

You send in the unit as a parcel or book a UPS collection for an extra charge; after the repair, Airbag24 returns it by UPS. Put the printed repair order into the parcel and pack the unit shock-proof.

A sturdy box with enough padding protects the electronics on the way.
