Airbag control unit with part number 95910-2B100

What does the airbag control unit 95910-2B100 do?

As a central unit, the airbag control unit 95910-2B100 controls the SRS restraint system of Hyundai. It evaluates the crash sensors, decides in an accident within milliseconds on airbags and seatbelt pretensioners, and monitors all components continuously. After an accident, it stores crash data and locks itself.

Faults are reported via the airbag warning light so that the driver notices them.

An intact control unit is therefore the prerequisite for the restraint system to work fully in an emergency.

Why does the control unit 95910-2B100 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot clear it. Additional causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Storage affects the control unit itself; merely reading it out does not fix it. This is why, in the event of suspicion, you should first think of an earlier accident.

The other causes belong to everyday vehicle use: components age, solder joints lose their firmness, moisture gets into plugs, and a weak battery loads the electronics with voltage spikes.

How can you tell that the 95910-2B100 is defective?

On the 95910-2B100, you recognise a defect by an airbag warning light in the instrument cluster that lights up permanently or intermittently, and by an error message in the instrument cluster. Connection problems with the diagnostic tool and a fault memory that cannot be cleared are also signs.

Typical signs at a glance:

• airbag warning light, permanently or intermittently
• error message in the instrument cluster
• no contact with the diagnostic tool
• fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may possibly fail to deploy. Therefore have such signs checked promptly.

On the one hand, 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, have the fault memory read out beforehand, because only this result shows whether the control unit is defective or a plug or cable is the cause.

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