Airbag control unit with part number 95910-1M550

What does the airbag control unit 95910-1M550 do?

The airbag control unit 95910-1M550 forms the control centre of the restraint system (SRS) at Kia. It processes the signals from the crash sensors and determines in an emergency which airbags and seatbelt pretensioners are triggered. After an accident it stores crash data and locks itself.

Monitoring runs throughout every journey, and detected faults appear as a fault entry in the memory.

The airbag warning light in the instrument cluster shows you the state of the system.

Why does the control unit 95910-1M550 fail?

With the 95910-1M550, the most common cause is crash data stored after an accident, even if no airbag has deployed. A normal diagnostic tool cannot erase these entries. Other causes are aged components, moisture at plug connectors and voltage spikes.

Crash data is an entry in the unit, not component damage. That is why the fault remains visible to the workshop.

The other causes lie in the electronics and their connections: cold solder joints on the circuit board, moisture and corrosion at plug connectors, and ageing of the components.

Voltage spikes, for example from a weak battery or from jump-starting, add further strain to the electronics.

How can you tell that the 95910-1M550 is defective?

A fault in the 95910-1M550 shows up as the airbag warning light staying on permanently or intermittently, along with a fault message in the instrument cluster. Add to that no connection to the diagnostic tool and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

Anyone who watches the warning light will notice the signal fastest, because it sits in your field of view. The other signs give additional information about the condition of the unit.
