Airbag control unit with part number 8200435339

What does the airbag control unit 8200435339 do?

The airbag control unit 8200435339 manages the restraint system (SRS) in Renault. It evaluates the crash sensors, determines in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system constantly.

The unit reports faults to the airbag warning light in the instrument cluster. After an accident it stores crash data and locks itself.

The unit carries out these tasks in the background, without you noticing anything.

Why does the control unit 8200435339 fail?

The most common cause with the 8200435339 is crash data stored after an accident, even if no airbag was triggered. In addition there are aged electronics, moisture at plugs and voltage spikes.

Stored crash data cannot be removed with usual diagnostic tools. Airbag24 removes it during the repair.

Cold solder joints and aged components can also cause the failure, and moisture or corrosion at plug connections contribute as well.

Voltage spikes, for example from a weak battery or a jump start, stress the unit just as much.

How can you tell that the 8200435339 is defective?

A defect on the 8200435339 shows itself through an airbag warning light that lights up permanently or intermittently. Fault messages also appear in the instrument cluster, the diagnostic tool finds no connection, and the fault memory cannot be cleared.

The airbag warning light in the instrument cluster is the most important sign of the system's condition. If it lights up, the system has detected a fault.

In an emergency, airbags and seatbelt pretensioners may therefore fail to trigger. So have the finding clarified promptly.
