Airbag control unit with part number 8200246184

What does the airbag control unit 8200246184 do?

The airbag control unit 8200246184 is the central control unit of the restraint system (SRS) in Renault. It evaluates the signals from the crash sensors and, in a crash, decides within fractions of a second which airbags and seatbelt pretensioners are triggered.

At the same time it monitors the system continuously and reports faults via the airbag warning light in the instrument cluster. The sensors are connected to the unit by cable.

After a crash, the control unit stores crash data and locks itself.

Why does the control unit 8200246184 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a standard diagnostic tool cannot erase it. Other general causes may also come into consideration.

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

Stored crash data does not automatically mean that the electronics are damaged. Whether a component is defective only becomes clear when Airbag24 inspects it in its workshop.

How can you tell that the 8200246184 is defective?

A fault shows when the airbag warning light in the instrument cluster lights up permanently or intermittently. In addition, a fault message appears in the instrument cluster, the diagnostic tool cannot connect to the control unit, and the fault memory cannot be cleared.

If the light only comes on intermittently, this is still a warning sign. A fault memory that cannot be emptied is likewise a sign that something in the system is wrong.

In the event of a defect, airbags and seatbelt pretensioners may possibly fail to trigger, so it is worth having the fault memory read out promptly.
