What does the airbag control unit 95910-4H580 do?

The airbag control unit 95910-4H580 forms the central unit of the restraint system (SRS) for Hyundai. It checks the signals from the crash sensors and in a crash triggers the matching airbags and seatbelt pretensioners within milliseconds.

The system monitors the unit constantly. It shows faults via the airbag warning light in the instrument cluster.

After an accident the unit stores crash data and locks itself.

Why does the control unit 95910-4H580 fail?

The most common cause lies in crash data stored after an accident, even if no airbag fired. Further causes are aged components, moisture and corrosion, cold solder joints and voltage spikes.

• aged electronic components
• moisture and corrosion on plug connectors
• cold solder joints
• voltage spikes, for example from a weak battery or a jump start

Crash data cannot be erased with a normal diagnostic tool. The other causes can only be identified by checking the unit.

How can you tell that the 95910-4H580 is defective?

The airbag warning light gives the first indication, because it lights up permanently or intermittently. There are further signs as well.
