Airbag control unit with part number 8200117653

What does the airbag control unit 8200117653 do?

In the restraint system (SRS) for Renault, the airbag control unit 8200117653 evaluates the crash sensors. In an accident it decides within milliseconds on airbags and seatbelt pretensioners and monitors the system continuously.

If the unit detects a fault, it shows it via the airbag warning light. Monitoring runs continuously in the background.

After an accident the unit stores crash data and locks itself. This state is the starting point for every later diagnosis.

Why does the control unit 8200117653 fail?

The most common cause is stored crash data from an accident, even if no airbag has deployed. Other causes are components that age, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Crash data cannot be removed with a normal diagnostic tool, and Airbag24 erases it during the repair. The other triggers in detail:

• electronic components that lose their function over time
• solder joints with a cold connection
• moisture or rust at the connectors
• voltage spikes, for example after a jump start

How can you tell that the 8200117653 is defective?

The airbag warning light in the instrument cluster, which stays on permanently or intermittently, indicates the fault. A fault message in the instrument cluster, a lack of contact with the diagnostic tool and a fault memory that cannot be emptied may also appear. In an emergency, airbags and seatbelt pretensioners may then not deploy.

The light is the notice you will see first, and it requires clarification even if the vehicle continues to drive.

If the diagnostic tool has trouble connecting, the cause may lie in the control unit or in its connection. Only reading out the fault memory shows which cause applies.
