Airbag control unit with part number 95910-4M150

What does the airbag control unit 95910-4M150 do?

The 95910-4M150 forms the switching centre of the restraint system (SRS) in Kia. From the messages of the crash sensors it calculates within milliseconds whether airbags and seatbelt pretensioners must be fired. After an accident it stores crash data and locks itself, and the repair ends the lock.

While driving, the unit continuously checks the wiring and all connected sensors. If it detects a fault, it switches on the airbag warning light in the instrument cluster so that you can keep an eye on the state of the system.

Why does the control unit 95910-4M150 fail?

The most common cause is crash data that remains in memory after an accident, even if no airbag has fired. A standard diagnostic tool cannot access this data. Added to this are aged components, cold solder joints, moisture and corrosion in connectors, and voltage spikes, for example from a weak battery or a jump start.

The crash data remains in memory even when the accident was harmless for the occupants and no airbag was triggered.

The other causes develop over time. Electronics age, solder joints can give way, and penetrating moisture attacks the contacts.

Voltage spikes occur, for example, when the battery is weak or when jump-starting with external power. Such surges in the vehicle electrical system can stress components.

How can you tell that the 95910-4M150 is defective?

The clearest sign is the airbag warning light in the instrument cluster, which stays on permanently or only intermittently. Diagnostic tools then cannot reach the control unit, and messages appear in the instrument cluster.

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

If any of these signs are present, airbags and seatbelt pretensioners may not deploy in an emergency. Therefore have the system checked promptly.

Which vehicles is the 95910-4M150 fitted in?

Each part number belongs to a specific type of unit. The control unit 95910-4M150 is fitted in these vehicles: Kia K5 TF (2010-2015); Kia Optima TF (2010-2015).

The list shows which models we have recorded for this number:

• Kia K5 TF (2010-2015)
• Kia Optima TF (2010-2015)

On the one hand, compare the number on the label of the removed unit with this page; this only confirms the correct unit. On the other hand, have the fault memory read out before removal. Only this result shows whether the control unit itself is defective or a plug or a cable is the cause.

For the same vehicles, we also repair control units with the part numbers 95910-2T000, 95910-2T010, 95910-2T100, 95910-2T110, 95910-2T210, 95910-2T300.

How does the repair of the 95910-4M150 work?

First have the fault memory read out and attach the log. Then disconnect the battery and only then remove the control unit. Use our online form to create the repair order and send the well-packed unit to us.

At Airbag24 the unit is first examined on the test bench. We replace defective components, erase stored crash data, and then a function test follows. The unit is then returned to you.

Processing with us usually takes 3–4 working days. This time covers only the checking, repairing and testing.

Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit 95910-4M150 get to Airbag24?

You send the unit as a parcel, or you book a UPS collection for an extra charge. The return after the repair is made by UPS.

The printed repair order goes into the parcel. Pack the control unit shock-proof so that it survives transport undamaged.
