Airbag control unit with part number 95910-D4150

What does the airbag control unit 95910-D4150 do?

The airbag control unit 95910-D4150 is the control unit of the restraint system (SRS) for Kia. Via the crash sensors it evaluates how an accident unfolds, decides whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. After an accident it stores crash data and locks itself.

If a fault is detected, the unit indicates it via the airbag warning light. The display in the instrument cluster is therefore the warning signal for the driver.

Because the decision in a collision must be made within milliseconds, only reliable electronics can be the solution.

Why does the control unit 95910-D4150 fail?

Crash data from an accident that remains stored in the unit is the most common cause, even if no airbag has been triggered. It cannot be erased with a normal diagnostic tool. Other causes are aged components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

Stored crash data says nothing about whether an airbag has fired. It lies in the control unit and cannot be removed with the usual tools.

Aged components, cold solder joints, moisture and corrosion are rather insidious causes. Voltage spikes from the vehicle electrical system, for example with a weak battery or jump-starting, come on top of them as triggers.

How can you tell that the 95910-D4150 is defective?

Typical signs of a defect in the 95910-D4150 are an airbag warning light that stays on permanently or intermittently, and fault messages. In an emergency, airbags and seatbelt pretensioners may fail to deploy.

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

Each of these signs justifies a check, regardless of how often the light comes on.

Whether the control unit itself or a cable is affected is revealed only by reading out.

Comparing the part number with the label of the removed unit ensures that it is the right unit. It says nothing about the cause. So have the fault memory read out before removal: only the log shows whether the control unit is defective or whether a plug or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95910-D5000.
