Airbag control unit with part number 95910-O3500

What does the airbag control unit 95910-O3500 do?

The airbag control unit 95910-O3500 coordinates the restraint system of Kia. It processes the messages from the crash sensors, determines within milliseconds which airbags and seatbelt pretensioners are triggered, and monitors the system without interruption. After an accident, it stores crash data and locks itself.

The unit detects faults itself and passes them on via the airbag warning light, so that the driver is informed.

The triggering decision is based solely on the sensor signals that the unit evaluates.

Why does the control unit 95910-O3500 fail?

The 95910-O3500 most often fails because of the crash data stored after an accident, even if no airbag has deployed; a normal diagnostic tool cannot erase this data. Aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or a jump start are also considered as causes.

The crash data entry is an event memory. It records that the unit has registered an accident, and it remains until the repair removes the data.

The electrics are also worth a look. Solder joints on the circuit board can cause contact problems over time, and moisture attacks plug connections. Strong voltage fluctuations when starting or when connecting an external battery also stress the electronics.

How can you tell that the 95910-O3500 is defective?

Typical signs on the 95910-O3500 are the airbag warning light, which lights up constantly or intermittently, a fault message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to deploy.

The signs at a glance:

• airbag warning light lights up constantly or intermittently
• fault message in the instrument cluster
• diagnostic tool does not connect to the control unit
• fault memory cannot be cleared

If a warning appears, have the system checked promptly rather than waiting.

Comparing the part number on the label of the removed control unit with this page ensures that it is the correct unit. It says nothing about the cause, however. So have the fault memory read out beforehand, because the log shows whether the unit itself is the cause or a plug or cable.

How does the repair of the 95910-O3500 work?

First have the fault memory read out and attach the log to the unit. Then disconnect the battery and remove the control unit 95910-O3500. Next, create a repair order online and send the unit in well packed. At Airbag24, testing, repair and function check usually need 3–4 working days.
