Airbag control unit with part number 95940-L5100

What is the function of the Airbag Control Unit 95940-L5100?

The Airbag Control Unit 95940-L5100, also known as the SRS module, is the central control unit for the passive safety system in the Kia K5 DL3. It is responsible for monitoring all relevant sensors, evaluating crash situations, and precisely activating the airbags and seatbelt pretensioners at the correct timing.

As the brain of the restraint system, the 95940-L5100 module continuously processes data from acceleration and G-sensors. In the event of a collision exceeding predefined thresholds, it sends ignition signals to the corresponding pyrotechnic components.

The primary task of the control unit is to maximize occupant safety by precisely coordinating the restraint systems according to the severity and nature of the accident. Therefore, flawless operation is crucial for vehicle safety.

Why does the Airbag Control Unit 95940-L5100 fail?

The most common reason for needing repair on the 95940-L5100 control unit is the storage of crash data after an accident. Other causes include internal electronic malfunctions leading to communication loss, as well as failure of individual components on the circuit board, which triggers specific error codes.

After an airbag deployment—even in minor collisions—the control unit permanently stores so‑called “crash data.” This lockout prevents reuse and must be cleared through specialized intervention in the device’s memory. This is a designated safety mechanism.

Another frequent cause of failure is loss of communication. The control unit then no longer responds to diagnostic equipment requests. This often indicates an internal hardware fault, such as issues with the power supply or the module’s processor.

Failure of individual electronic components on the circuit board can also result in specific error codes. The diagnostic system may then report faults in the SRS modules or their connected components, even though these appear externally intact.

How do you recognize a defect in the 95940-L5100 control unit?

A defect in the Airbag Control Unit 95940-L5100 primarily manifests as a constantly illuminated airbag warning light on the instrument panel. Additional signs include lack of communication with diagnostic equipment or the storage of specific error codes indicating an internal device malfunction.

The clearest symptom is the airbag warning light that fails to turn off after starting the engine or flashes sporadically during driving. This signals a fault in the safety system that requires immediate inspection.

In the workshop, the defect often becomes apparent when the control unit is no longer accessible via the OBD interface. Diagnostic tools cannot establish a connection, making fault analysis impossible and pointing to a serious internal issue.

Sometimes, specific error codes are stored in the fault memory, directly indicating an internal malfunction within the SRS module. These codes suggest that connected components like airbags or sensors are functioning properly, while the problem lies within the control unit itself.

In which vehicles is the 95940-L5100 control unit installed?

The Airbag Control Unit with part number 95940-L5100 is specifically used in vehicles manufactured by Kia. It is the standard SRS module for the third-generation Kia K5 model series (internal designation DL3), produced starting in the 2019 model year.

At Airbag24, we repair the 95940-L5100 control unit for the following specific model:

Kia: K5 (DL3 generation, from 2019)

Since this is a model-specific component, it is essential to verify the part number carefully before removal and shipment to ensure proper identification and repair.

How is the 95940-L5100 control unit professionally repaired?

Repair of the 95940-L5100 control unit at Airbag24 includes professional deletion of crash data, diagnosis, replacement of defective electronic components on the circuit board, and a complete system reset. Final functional tests confirm full operability.

Before sending the unit in, it is important that a qualified workshop clearly attributes the fault to the control unit and ideally provides a diagnostic report. This ensures that the root cause is not in the wiring or external sensors, as control units are expensive replacement parts.

Upon receipt at Airbag24, the control unit undergoes an initial inspection. Depending on the nature of the fault, the core of the repair involves erasing stored crash information from the memory chip or replacing defective components on the circuit board.

Subsequently, the control unit is reset to its factory settings and undergoes a comprehensive functional test. Upon successful testing, the device is fully operational again. We provide a 12-month warranty on all repairs.

What shipping options does Airbag24 offer?

Airbag24 offers flexible and secure shipping options. You can send your control unit back at no cost yourself or arrange a convenient UPS pickup. Returns are also handled reliably by UPS, with your choice of free standard shipping or faster express service, including cash-on-delivery.

For sending the unit back, you have two options: securely package the removed control unit and ship it to us yourself, or schedule a UPS pickup at a location and date of your choosing.

The return shipment of the repaired unit is free for you as standard UPS shipping.

For faster delivery, we offer UPS express shipping. Both standard and express shipping can optionally be paid for by cash-on-delivery. Alternatively, upon prior arrangement, you may also pick up your device in person from our facility.
