Airbag control unit with part number 8200682382

What does the airbag control unit 8200682382 do?

The airbag control unit 8200682382 is the central control unit of the restraint system (SRS) in the Renault. It evaluates the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered.

During driving, it monitors all components of the system. It reports faults via the airbag warning light in the instrument cluster.

After an accident, it secures crash data and locks itself. Only the repair lifts the lock.

Why does the control unit 8200682382 fail?

Most often, crash data from an earlier accident are present, even if no airbag has triggered. A normal diagnostic tool cannot remove them. Other causes in brief are:

• Aged electronic components
• Cold solder joints
• Moisture and corrosion at plug connections
• Voltage spikes, for example from a weak battery or a jump start

Airbag24 removes the stored crash data during the repair. The other causes affect the electronics and their connections over the years.

How can you tell that the 8200682382 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears. The diagnostic tool does not connect to the control unit, and the fault memory cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

These signs can occur together:

• Airbag warning light staying on permanently or intermittently
• Error message in the instrument cluster
• No access from the diagnostic tool to the control unit
• Fault memory that cannot be cleared
