Airbag control unit with part number 8200682387

What does the airbag control unit 8200682387 do?

The airbag control unit 8200682387 controls the restraint system (SRS) for Renault. It receives the messages from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners to trigger.

At the same time, the unit checks the system continuously. A detected fault appears on the airbag warning light, and after an accident the control unit stores crash data and locks itself.

Why does the control unit 8200682387 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed. Added to this are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or a jump start.

Crash data cannot be erased with a normal diagnostic tool. The unit therefore remains conspicuous for as long as the data is held in the memory.

Ageing components, cold solder joints and corrosion belong to the general causes. Moisture attacks plug connections and disturbs the contact.

Voltage spikes stress the electronics above all when the battery is weak or a vehicle is started with a jump start.

How can you tell that the 8200682387 is defective?

A defect shows up on the airbag warning light in the instrument cluster, which lights permanently or intermittently. In addition there is a fault message, no connection to the diagnostic tool and a fault memory that cannot be cleared. In an emergency, the airbags and seatbelt pretensioners may then fail to trigger.

The warning light is a clear signal that something is wrong in the restraint system. A check is therefore the right next step.

A diagnostic tool that cannot establish a connection is a further sign that needs to be taken seriously.
