Airbag control unit with part number 95910-4Q300

What does the airbag control unit 95910-4Q300 do?

The airbag control unit 95910-4Q300 coordinates the restraint system (SRS) in the Kia vehicle. Using the crash sensors it calculates which airbags and seatbelt pretensioners are triggered, and it monitors the circuits of the entire system.

This decision is made in fractions of a second in an accident. Beforehand the unit checks continuously whether all components function.

It shows faults with the airbag warning light in the instrument cluster. If an accident has occurred, it stores crash data and locks itself. The lock is only lifted by the repair.

Why does the control unit 95910-4Q300 fail?

Stored crash data from an accident come first, because they are the most common cause, even when no airbag has triggered. A usual diagnostic tool cannot delete them, and Airbag24 removes them during the repair. Other causes are aged components, cold solder joints, moisture, corrosion and voltage spikes.

Crash data are the records from the accident. They remain in the memory until they are deleted.

Aged components and cold solder joints can cause faults that only appear during operation. Moisture and corrosion at plug connections disturb the connection between the components.

Voltage spikes, for example with a weak battery or jump starting, additionally strain the electronics.

How can you tell that the 95910-4Q300 is defective?

You recognise a defect on the 95910-4Q300 by an airbag warning light that stays on permanently or intermittently, by an error message in the instrument cluster, by a diagnostic tool without connection to the control unit or by a fault memory that cannot be cleared. Such a finding can mean that airbags and seatbelt pretensioners may not trigger in an emergency.

The signs in detail:

• Airbag warning light that stays on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool without connection to the control unit
• Fault memory that cannot be cleared

If you notice one of these signs, have the system checked promptly. The warning light is the hint that the vehicle itself gives.
