Airbag control unit with part number 8200682395

What does the airbag control unit 8200682395 do?

The airbag control unit 8200682395 belongs to the restraint system (SRS) for Renault. It evaluates the signals from the crash sensors and determines in a crash which airbags and seatbelt pretensioners are triggered. Between events it monitors the system without interruption.

Detected faults are shown via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself.

Why does the control unit 8200682395 fail?

Most often the cause is crash data from an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Ageing components, moisture, cold solder joints and voltage spikes also play a part.

An impact without deployment also leaves traces, which is why it is worth looking at the memory.

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

The cause in the individual case becomes clear only once the fault memory has been read out.

How can you tell that the 8200682395 is defective?

The airbag warning light in the instrument cluster lights up constantly or only intermittently. A fault message accompanies it, the diagnostic tool cannot find the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then not be able to trigger.

If the light is on or the instrument cluster reports a fault, have the system checked promptly.

Whether the control unit itself is affected or the wiring is shown only by the diagnosis.
