What is a Kia Sorento UM airbag control unit?
The Kia Sorento UM airbag control unit is the central safety unit in your vehicle, precisely controlling and deploying all restraint systems, such as airbags and seatbelt pretensioners, in the event of a collision. It continuously monitors the sensors, stores important crash data, and is essential for the proper functioning of your entire airbag system.
This SRS (Supplemental Restraint System) module is responsible for continuous system integrity.
After an accident or internal errors, the function must be restored to ensure safe continued driving.
Why is the Kia Sorento UM airbag control unit defective?
A Kia Sorento UM airbag control unit can fail due to internal memory corruption, often resulting from stored crash data after an accident, or due to power supply problems affecting the electronics. These defects cause the airbag warning light to stay permanently illuminated, rendering the system inoperable.
Errors like code B1620 directly indicate an internal defect in the control unit.
Low supply voltage, manifested by the code B1102, can also seriously disrupt the operational readiness and make an immediate Kia Sorento UM airbag control unit repair necessary.
Common error codes for Kia Sorento UM airbag control unit repair
During Kia Sorento UM airbag control unit repairs, specific error codes occur that indicate problems with the control unit itself, rather than with sensors or other components. Recognizing these codes is crucial for an accurate diagnosis and successful repair.
- B1620 → Internal memory error / control unit defective → Cause: Damaged software or hardware in the control unit, often after an accident.
- B1102 → Supply voltage too low → Cause: Problems with the power supply to the airbag control unit.
These OBD-II B codes relate exclusively to the airbag control unit.
After replacing or repairing the control unit, it is essential to erase the error memory and perform VIN-specific programming in a specialized workshop.
What part numbers are available for Kia Sorento UM airbag control unit repair?
For Kia Sorento UM airbag control unit repairs, exact OEM part numbers are crucial to ensure compatibility with your vehicle, as an incorrect part number can lead to system failure. A thorough verification of the part number directly on the control unit in the vehicle is essential before any repair or replacement.
The main OEM part number for the Kia Sorento UM (third generation, approximately 2016-2020) is 95910-1U150.
For adjacent model years (2009-2012), part number 95910-1U000 is another validated option, although a VIN comparison is strongly recommended.
- 95910-1U150 → Kia OEM → Airbag control unit Kia Sorento UM (third generation)
- 95910-1U000 → Kia OEM → Airbag control unit Kia Sorento (older models, e.g. 2009-2012)
A replacement or repair always requires programming the control unit to the vehicle identification number (VIN) by a Kia workshop.
If you need assistance with VIN retrieval or programming, a qualified Kia dealer or specialized airbag service center can provide the necessary assistance with your Kia Sorento UM airbag control unit repair.
