Airbag control unit with part number 95910-4U100

What does the airbag control unit 95910-4U100 do?

The airbag control unit 95910-4U100 coordinates the restraint system (SRS) in the Kia. It processes the signals from the crash sensors and triggers the appropriate airbags and seatbelt pretensioners within milliseconds in an accident.

While driving, it monitors the system continuously. It indicates faults via the airbag warning light.

If an accident has occurred, the unit stores crash data and locks itself. The lock is lifted only by the repair.

Why does the control unit 95910-4U100 fail?

The most common cause of the 95910-4U100 is crash data stored after an accident, even if no airbag has been triggered. A normal diagnostic tool cannot delete it. Aged components, cold solder joints, moisture at plug connections and voltage spikes also play a role.

The stored data keeps the fault in the unit until the repair removes it. Reading out the fault memory alone does not change this.

The other causes mainly affect the electronics and their connections. Components lose reliability with age, and solder joints can become cold. Moisture and corrosion at plugs disrupt the contact, while voltage spikes, for example from a weak battery or a jump-start, stress the components.

How can you tell that the 95910-4U100 is defective?

A defect in the 95910-4U100 shows up as the airbag warning light, which lights up permanently or intermittently, and as an error message in the instrument cluster. In addition, the diagnostic tool has no connection to the control unit, and the fault memory cannot be cleared.

The signs at a glance:

• Airbag warning light in the instrument cluster lights up permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

In an emergency, airbags and seatbelt pretensioners may then not trigger. Such a finding should therefore be clarified promptly.
