Airbag control unit with part number 95910-CZ200

What does the airbag control unit 95910-CZ200 do?

The airbag control unit 95910-CZ200 controls the restraint system (SRS) of Hyundai. Via the crash sensors it determines whether an accident has occurred, triggers airbags and seatbelt pretensioners when required, and reports faults via the airbag warning light.

The decision is made in fractions of a second, because there is no time for delays during an impact. In everyday operation the unit continuously checks its circuits and the connected components.

After an accident the control unit stores crash data and locks itself. The unit records this data even when no airbag has been triggered.

Why does the control unit 95910-CZ200 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed, and a normal diagnostic tool cannot delete it. Other causes include aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes, for example from a weak battery or jump-starting.

The crash data remains in the memory even when the vehicle is driven normally again. That is why the warning light can stay on although hardly anything can be seen on the bodywork. Airbag24 deletes the crash data during the repair.

The other causes tend to develop gradually. Components age over time, solder joints can give way, and moisture or corrosion attack plug connectors. Voltage spikes from the vehicle electrical system put additional strain on the electronics.

How can you tell that the 95910-CZ200 is defective?

A defect shows up as an airbag warning light that is on permanently or intermittently, an error message in the instrument cluster, a missing connection to the diagnostic tool, or a fault memory that cannot be cleared.

• Airbag warning light is on permanently
• Airbag warning light is on intermittently
• Fault message in the instrument cluster
• Diagnostic tool has no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may not trigger if the control unit is defective. If you notice any of these signs, have the system checked promptly.

Whether the control unit is actually affected can only be established by reading out the fault memory. One sign alone is not enough for that.

Which vehicles is the 95910-CZ200 fitted in?

• Hyundai Tucson NX4 (2020-2023)
• Hyundai Tucson NX4 Facelift (from 2023)

You can compare the part number on the label of the removed unit with this page, but that only confirms the correct unit. Whether the control unit is defective or a plug or cable is the cause is shown only by the fault memory read out beforehand.

For the same vehicles, we also repair control units with the part numbers 28394001, 95910-CH310, 95910-CH320, 95910-CH610, 95910-CH620, 95910-CH630.
