Airbag control unit with part number 95910-4Z100

What does the airbag control unit 95910-4Z100 do?

The airbag control unit 95910-4Z100 forms the central control unit of the restraint system (SRS) for Hyundai. It evaluates the crash sensors and decides in an emergency within milliseconds which airbags and seatbelt pretensioners are triggered.

Outside an accident the unit checks all connected components of the system continuously. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

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

Why does the control unit 95910-4Z100 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase it. Other causes are:

• ageing electronic components
• cold solder joints on the circuit board
• moisture and corrosion at plug connections
• voltage spikes, for example with a weak battery or jump-starting

The crash data can therefore be in memory even if no airbag was triggered in the accident. That is exactly why it is worth paying attention to the displays after every accident.

Which of the other causes plays a role in an individual case is only shown by the investigation at the workshop.

How can you tell that the 95910-4Z100 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, an error message appears in the display, the diagnostic tool finds no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, airbags and seatbelt pretensioners may possibly not trigger in the event of a defect. A lit warning light is therefore a reason to have the vehicle checked promptly.

The light reports the fault itself; a glance at the instrument cluster is enough to notice it.

First compare the part number on the label of the removed unit with this page. This only confirms that it is the right unit, but says nothing about its condition. Also have the fault memory read out, because only that shows whether the control unit itself is defective or a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95700-2B110, 95910-0W100, 95910-26100, 95910-2B028, 95910-2B900, 95910-2B970.
