Airbag control unit with part number 95910-4Z000

What does the airbag control unit 95910-4Z000 do?

In the Hyundai, the airbag control unit 95910-4Z000 is the switching centre of the restraint system (SRS). It evaluates the crash sensors and, in a crash, determines within milliseconds which airbags and seatbelt pretensioners fire.

In addition, it monitors all components of the system continuously. It shows faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. The repair lifts this lock.

Why does the control unit 95910-4Z000 fail?

Stored crash data after an accident is the most common cause, even when no airbag has deployed. A normal diagnostic tool cannot erase it. In addition, ageing electronic components, cold solder joints, moisture and corrosion on plug connections, as well as voltage spikes, come into consideration.

Crash data does not disappear from the memory on its own. Airbag24 removes it during the repair; you do not need to do anything for this.

The other causes act over time. Components age, solder joints can go cold, and moisture attacks the contacts. A weak battery or a jump start can cause voltage spikes.

How can you tell that the 95910-4Z000 is defective?

The airbag warning light stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, the diagnostic tool cannot establish a connection with the control unit, and the fault memory cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then possibly fail to deploy.

These signs are the basis for having the fault memory read out:

• Airbag warning light staying on permanently or intermittently
• Error message in the instrument cluster
• No connection between diagnostic tool and control unit
• Fault memory that cannot be cleared
