Airbag control unit with part number 8200358577

What does the airbag control unit 8200358577 do?

The airbag control unit 8200358577 forms the control system of the restraint system (SRS) for Renault: it evaluates the crash sensors and decides in a crash whether airbags and seatbelt pretensioners are triggered. It signals faults via the airbag warning light. After a crash, it stores crash data and locks itself.

In a crash, every millisecond counts, so the checking runs without interruption while the vehicle is powered up.

Detected faults are stored by the unit in the fault memory, where they appear during a diagnosis.

Why does the control unit 8200358577 fail?

Causes with the 8200358577: stored crash data after a crash is the most common cause, even if no airbag has deployed. Other causes include aged components, moisture and voltage spikes. With this control unit, it is often not possible to erase the crash data; anyone who would like it erased should get in touch with Airbag24 briefly before sending the unit in.

The crash data remains in the memory even when the car has long since been driving again. A standard code reader cannot remove it, so the unit continues to report faults, even though the electronics themselves may be intact.

Aged electronics, cold solder joints and moisture at plug connectors can also be causes. Voltage spikes, for example from a weak battery or a jump start, add further strain.

How can you tell that the 8200358577 is defective?

Signs at the 8200358577: an airbag warning light that stays on in the instrument cluster, permanently or intermittently, is the most important sign. Other signs are an error message in the instrument cluster and no contact with the diagnostic tool. In an actual crash, the airbags and seatbelt pretensioners may not deploy.

Typical signs are:

• The warning light is permanently or intermittently on
• An error message in the instrument cluster
• No connection to the diagnostic tool
• The fault memory cannot be cleared

If you notice any of these signs, have the vehicle checked promptly.
