Airbag control unit with part number 95910-D3700

What does the airbag control unit 95910-D3700 do?

The airbag control unit 95910-D3700 controls the restraint system (SRS) of Hyundai. It evaluates the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The unit stores faults and reports them via the airbag warning light. In everyday driving you do not notice this monitoring at all.

After an accident, the unit creates crash data and then locks itself.

Why does the control unit 95910-D3700 fail?

The most common cause is crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot delete it. Aged components, moisture and voltage spikes are also possible causes.

Crash data remains in the unit until it is removed during the repair. Airbag24 carries out this step as part of the repair of the unit.

The other causes include ageing of the electronics, cold solder joints and corrosion at plug connections. Voltage spikes, for example from a weak battery or a jump start, can also damage a control unit.

How can you tell that the 95910-D3700 is defective?

A defect in the 95910-D3700 shows up as the airbag warning light, which stays on permanently or from time to time. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Typical signs are:

• airbag warning light is on permanently or from time to time
• fault message in the instrument cluster
• diagnostic tool gets no connection to the control unit
• fault memory cannot be cleared

The fact that the light is currently off does not mean the system is working properly. A fault message is therefore a reason to have the system checked.
