Airbag control unit with part number 8200962377

What does the airbag control unit 8200962377 do?

The airbag control unit 8200962377 manages the restraint system (SRS) of Renault. It evaluates the signals from the crash sensors, decides within milliseconds in the event of an accident whether airbags and seatbelt pretensioners are triggered, and reports faults via the airbag warning light.

The crash sensors continuously supply measured values to the control unit. The unit checks these values constantly so that it can react without delay in an emergency. It also monitors the other components of the system.

After an accident, the control unit stores crash data and locks itself. Faults it finds are recorded in the fault memory, which a diagnostic tool can read out.

Why does the control unit 8200962377 fail?

In the control unit 8200962377, stored crash data after an accident is the most common cause, even if no airbag has deployed. Other causes are ageing components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

A standard diagnostic tool cannot delete this crash data. That is why the cause remains stored in the unit.

The other causes affect the electronics themselves or their connections:

• ageing electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or jump-starting

Which of these applies in an individual case is only shown by the fault memory once it has been read out.

How can you tell that the 8200962377 is defective?

A defect shows up as the airbag warning light in the instrument cluster, which lights up permanently or intermittently. In addition there may be an error message in the instrument cluster, a diagnostic tool with no connection to the control unit 8200962377, and a fault memory that cannot be cleared.

The warning light is the most important signal, because it displays every fault detected. If it stays on after starting, have the system checked promptly.

If no connection to the control unit is established, the fault may lie in the unit itself or in the wiring between them. As long as the defect persists, airbags and seatbelt pretensioners may not trigger in an emergency.

Compare the part number on the label of the removed unit with this page, and you will know that it is the correct unit. Have the fault memory read out beforehand, because only it shows whether the control unit is defective or whether a plug or a cable is the cause. The label comparison therefore only confirms identity, not the cause.

For the same vehicles, we also repair control units with the part numbers 603989700, 607993600, 8200321999, 8200340431, 8200375209, 8200401303.

How does the repair of the 8200962377 work?

To repair the 8200962377, proceed in this order: first have the fault memory read out and enclose the log. Then disconnect the battery and only then remove the control unit. Next, create a repair order online and pack the unit carefully for dispatch.

Airbag24 checks the unit you send in on the test bench and repairs defective components. Airbag24 then deletes the stored crash data and carries out a function test. Afterwards your own unit is returned to you.

Processing at Airbag24 usually takes 3–4 working days. This time covers only the checking, repairing and testing carried out there.

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 8200962377 get to Airbag24?

You send the control unit 8200962377 as a parcel, or you book a UPS collection for an extra charge. After the repair, Airbag24 returns it to you by UPS.
