What does the airbag control unit 8200645163 do?

The airbag control unit 8200645163 coordinates the restraint system (SRS) for Renault.

It reports faults via the airbag warning light.

Why does the control unit 8200645163 fail?

The most common cause is crash data saved after an accident, even if no airbag has deployed; a normal diagnostic tool cannot remove this data. Added to this are aged components, cold solder joints, moisture and corrosion on connectors, as well as voltage spikes.

The combination of ageing and moisture is hard to spot from outside, which is why the read-out of the fault memory is decisive.

Voltage spikes arise, for example, from a weak battery or when starting with a jump start.

How can you tell that the 8200645163 is defective?

Start with the airbag warning light in the instrument cluster, which lights up permanently or from time to time. An error message in the instrument cluster appears alongside it, and the diagnostic tool gets no connection to the control unit.

In detail, these signs stand out:

• Airbag warning light that stays on permanently or comes on from time to time
• Error message in the instrument cluster
• No connection from the diagnostic tool to the control unit
• Fault memory that cannot be cleared
