Airbag control unit with part number 985107024R

What does the airbag control unit 985107024R do?

For the restraint system (SRS) of Renault, the airbag control unit 985107024R controls the triggering. It evaluates the signals from the crash sensors, selects the appropriate airbags and seatbelt pretensioners within milliseconds in an accident, and checks the system continuously. After an accident it stores crash data and locks itself.

The unit monitors the entire system at all times and reports deviations via the airbag warning light. It is one of the components on which occupants can rely in an emergency.

Why does the control unit 985107024R fail?

Most often the cause is crash data from an earlier accident, even without a triggered airbag, which a normal diagnostic tool does not remove. Further causes are aging electronics, cold solder joints, moisture and corrosion on plugs, and voltage spikes such as with a weak battery or jump start. Airbag24 removes the crash data during the repair.

Crash data is held in the memory of the control unit. The other causes affect either the electronics or their connections.

How can you tell that the 985107024R is defective?

The airbag warning light in the instrument cluster signals the fault as soon as it lights up permanently or intermittently. Added to this are an error message, a diagnostic tool with no connection to the control unit, and a fault memory that cannot be emptied. Then airbags and seatbelt pretensioners may possibly not trigger in an emergency.

These signs are a clear indication from the system itself. Take them as a reason to have the cause checked promptly.
