Airbag control unit with part number 606083400

What does the airbag control unit 606083400 do?

The airbag control unit 606083400 coordinates the restraint system (SRS) of Renault. It monitors the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds in a crash. After an accident it stores crash data and locks itself.

The unit checks the entire system permanently. If it finds a fault, it shows this via the airbag warning light in the instrument cluster.

Precisely because the control unit works in the background, its condition only becomes noticeable in everyday life through this display.

Why does the control unit 606083400 fail?

The most common cause is crash data stored after an accident, even without an airbag having been triggered; a normal diagnostic tool cannot erase it. In brief, further causes are ageing components, cold solder joints, moisture and corrosion, and voltage spikes.

• ageing electronics
• cold solder joints
• moisture and corrosion at plug connectors
• voltage spikes, for example from a weak battery

Only an examination of the unit shows which cause applies in an individual case.

Plug connectors in particular are hard to judge from the outside, so the cause remains open for the time being.

How can you tell that the 606083400 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. The diagnostic tool finds no connection to the control unit, or the fault memory cannot be cleared.

If these signs occur, airbags and seatbelt pretensioners may not be able to trigger in an emergency. Every irregularity therefore deserves prompt inspection at a workshop.

The warning light is the clearest hint that the car itself gives.
