Airbag control unit with part number 95910-4H480

What does the airbag control unit 95910-4H480 do?

The airbag control unit 95910-4H480 is the central control unit of the restraint system (SRS) in Hyundai. It evaluates signals from the crash sensors and, in an accident, decides within milliseconds whether airbags and seatbelt pretensioners are triggered. After an accident, it stores crash data and locks itself.

During ongoing operation, the unit monitors the connected components. If it finds an irregularity, it creates a fault entry that a diagnostic tool can read out.

Airbags and seatbelt pretensioners only work reliably if the control unit functions flawlessly.

Why does the control unit 95910-4H480 fail?

Most often it is caused by crash data stored after an accident, even if no airbag has triggered. Other causes can be summarised briefly as follows.

An accident without a triggered airbag can still leave crash data behind, and a normal diagnostic tool cannot erase it. In addition, the following causes come into consideration:

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

The other causes develop over a longer period and cannot be reliably judged from the outside.

How can you tell that the 95910-4H480 is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently, and a fault message appears in the instrument cluster. If the diagnostic tool finds no connection to the control unit or the fault memory cannot be erased, a defect is likely.

In a defect, airbags and seatbelt pretensioners may not trigger in an emergency. The light is a warning signal; address it promptly.

On the one hand, you compare the part number on the label of the removed unit with this page; this only confirms that it is the correct unit. On the other hand, you have the fault memory read out beforehand, because only this shows whether the control unit itself is defective or a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 285001924, 285001925, 95910-4H080, 95910-4H500, 959104H600, SA310720000.
