Airbag control unit with part number 95910-4M300

What does the airbag control unit 95910-4M300 do?

In the restraint system (SRS) for Kia, the airbag control unit 95910-4M300 plays the central role. It evaluates the crash sensors, selects the airbags and seatbelt pretensioners to be triggered in an accident, and monitors the entire system. After an accident, it stores crash data and locks itself.

The decision is made within milliseconds. The unit reports faults via the airbag warning light in the instrument cluster.

Why does the control unit 95910-4M300 fail?

The most common cause of a 95910-4M300 failure is stored crash data after an accident, even if no airbag was deployed. A normal diagnostic tool cannot clear this data. Other causes are ageing electronic components, dry solder joints, moisture, corrosion on plug connections and voltage spikes.

Airbag24 clears the crash data during the repair. Voltage spikes occur, for example, with a weak battery or when jump-starting the vehicle.

The other causes develop gradually, and only the test will show which of them is present.

How can you tell that the 95910-4M300 is defective?

The airbag warning light in the instrument cluster lights up on the 95910-4M300 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.

In an emergency, airbags and seatbelt pretensioners may then fail to deploy. The light shows the defect, so having it checked promptly is the right step.
