Airbag control unit with part number 95910-3W400

What does the airbag control unit 95910-3W400 do?

The airbag control unit 95910-3W400 is the control unit of the restraint system (SRS) for Kia. It evaluates signals from the crash sensors, decides in an accident on airbags and seatbelt pretensioners, and monitors the system constantly. After an accident it stores crash data and locks itself.

Detected faults are passed on to the airbag warning light in the instrument cluster so that they become visible.

Triggering depends on many sensor values at the same time, which is why a central unit must bring them together reliably.

Why does the control unit 95910-3W400 fail?

The most common cause is stored crash data, even if no airbag was triggered; a normal diagnostic tool does not remove it. Other causes are aged electronics, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from the battery or jump starting.

Stored crash data remains in the unit until it is removed. Airbag24 deletes it during the repair; a diagnostic tool with usual equipment is not sufficient for that.

The other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from jump starting

How can you tell that the 95910-3W400 is defective?

The airbag warning light stays on permanently or lights up intermittently, an error message is shown in the instrument cluster, and the diagnostic tool finds no connection. If the fault memory cannot be cleared, that is a further sign. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The warning light is the clearest indication of a fault in the restraint system, and therefore deserves immediate attention.

The message in the instrument cluster and the missing contact with the diagnostic tool complement this picture. A fault memory that cannot be cleared remains a finding until it has been examined.

Compare the part number on the label of your removed unit with this page; that only confirms you have the right unit. Beforehand the fault memory must be read out, because only then does it show 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 0K082677F0, 95910-3W800, 959100Z200, 959103U100.
