Airbag control unit with part number 95910-K3400

What does the airbag control unit 95910-K3400 do?

As the central control unit of the restraint system (SRS), the airbag control unit 95910-K3400 works for Kia. It reads the sensor signals, decides in an accident whether airbags and seatbelt pretensioners are triggered and monitors the entire system. It displays faults via the airbag warning light.

The sensors report accelerations and impact signals, which the unit evaluates. After an accident it writes crash data to memory and then locks itself.

This makes it one of the most important components of passive safety.

Why does the control unit 95910-K3400 fail?

The most frequent cause is stored crash data from an accident, even without a triggered airbag. Ordinary diagnostic tools cannot erase it. Other causes are aged electronics, cold solder joints, moisture, corrosion and voltage spikes.

The crash data is kept in the control unit's memory and remains there after the accident. It cannot be removed with a commercially available diagnostic tool.

Aged electronics and cold solder joints can cause failures that become noticeable only slowly. Moisture and corrosion at plug connections impair contact, and voltage spikes, for example from a weak battery or a jump start, put strain on the electronics.

How can you tell that the 95910-K3400 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and an error message appears in the instrument cluster. The diagnostic tool then receives no connection to the control unit.

• lit airbag warning light, permanently or intermittently
• error message in the instrument cluster
• no connection between the diagnostic tool and the control unit
• fault memory that cannot be erased

In an emergency, airbags and seatbelt pretensioners may possibly fail to deploy. A prompt check is therefore advisable.
