Airbag control unit with part number 95910-4M500

What does the airbag control unit 95910-4M500 do?

The airbag control unit 95910-4M500 is responsible for controlling the restraint system (SRS) in Kia. It processes the measured values from the crash sensors, determines in a crash within milliseconds which airbags and seatbelt pretensioners to trigger, and checks the system without interruption.

A fault is indicated mainly by the airbag warning light. After an accident the unit stores crash data, and the function is locked afterwards.

Why does the control unit 95910-4M500 fail?

The most common cause is crash data after an accident, even if no airbag has deployed; a normal diagnostic tool cannot retrieve them. Other causes include aged components, cold solder joints, moisture on plugs and voltage spikes.

The crash data stay stored in the control unit, even if the vehicle shows no problems afterwards.

For the other causes, the age of the electronics plays a role. Solder joints lose contact over time, moisture and corrosion attack plug connections, and voltage spikes, for example from a weak battery, can strain the circuit.

How can you tell that the 95910-4M500 is defective?

The fault is mainly revealed by the airbag warning light when it stays lit or flashes. A fault message, a lack of contact with the diagnostic tool, or a fault memory that cannot be cleared also point to it. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Typical signs at a glance:

• The airbag warning light in the instrument cluster stays lit permanently or intermittently.
• The instrument cluster displays an error message.
• The diagnostic tool finds no connection to the control unit.
• The fault memory cannot be cleared.

Therefore have the system checked promptly.
