Airbag control unit with part number 98515-5RW8A

What is the function of the airbag control unit 98515-5RW8A?

The airbag control unit 98515-5RW8A is the central electronic module for the restraint system in the Nissan Kicks P15 from model year 2020 onwards. It is installed in the center console and responsible for controlling all airbag systems, storing crash data, and triggering fault codes when system malfunctions occur.

As a key component of passive vehicle safety, this module continuously processes data from various crash sensors throughout the vehicle. In the event of an accident, it makes the critical decision on which restraint systems—such as front, side, or knee airbags, as well as seatbelt pretensioners—must be deployed within milliseconds to provide optimal protection for occupants.

The part number 98515-5RW8A is the manufacturer’s current original equipment manufacturer (OEM) replacement part number, specifically designed for the Nissan Kicks P15, including the facelift models up to 2024. After a crash, the unit stores the crash data, often resulting in permanent immobilization.

What defects occur with 98515-5RW8A?

The most common defect of the control unit 98515-5RW8A is stored crash data following an accident that cannot be cleared. Other failures include loss of communication with diagnostic tools or internal hardware malfunctions in electronic components such as capacitors or sensors, leading to persistent system errors.

Following a crash, the control unit is locked for safety reasons by permanently retaining the crash event data in its internal memory. This lock often cannot be removed using standard workshop scanners and requires specialized chip-level repair.

Another frequent cause of failure is hardware damage directly on the circuit board. Individual electronic components like sensors, processors, or capacitors may fail. Such defects result in faulty system monitoring and necessitate repair to restore full functionality.

In some cases, total failure occurs, where the control unit no longer responds to diagnostic requests. It becomes inaccessible via the OBD interface, indicating a severe internal electronic malfunction.

How can you recognize a defect in the control unit 98515-5RW8A?

A defect in the control unit 98515-5RW8A primarily manifests as a constantly illuminated airbag warning light on the dashboard. Additionally, error messages such as “Airbag defective” or “Fuel shut-off valve” may appear. In severe cases, communication with the control unit via a diagnostic tool becomes impossible.

The clearest symptom is the persistently lit airbag warning light. It does not turn off after starting the engine, indicating a non‑erasable fault stored in the error memory and signaling deactivation of the entire airbag system.

Furthermore, specific fault codes may appear in the onboard computer or on the display, directly pointing to a malfunction in the restraint system. This can also involve disabling individual components, such as the driver’s or knee airbag.

When workshops attempt to read the error memory, communication with the control unit fails. The unit does not respond to diagnostic commands, preventing precise fault analysis and often requiring removal for further examination. Such symptoms frequently render the vehicle undrivable, as safety‑critical functions are disabled.

In which vehicles is the control unit 98515-5RW8A installed?

The part number 98515-5RW8A is the original airbag control unit specifically fitted in the Nissan Kicks of the P15 series. This includes both first-generation models from 2016 onward and the facelift models produced between 2020 and 2024.

At Airbag24, we offer professional repair services for the control unit 98515-5RW8A, used in the following models and series:

Nissan Kicks (P15 series, model years 2016–2020)

Nissan Kicks Facelift (P15 series, model years 2020–2024)

As a specific OEM part number, compatibility is limited to these Nissan Kicks generations, ensuring precise and reliable repairs.

Is repairing 98515-5RW8A worthwhile?

Repairing the control unit 98515-5RW8A is a cost-effective and sustainable alternative to expensive new purchases. It saves significant expenses, preserves the vehicle’s original condition, and avoids potential coding issues. With over 20 years of experience and more than 20,000 successful repairs, our success rate is exceptionally high.

A major advantage is the substantial cost savings compared to purchasing a new part from the manufacturer. Repair is often many times cheaper while fully restoring the original device’s functionality.

Since the original control unit remains in the vehicle and is merely refurbished, no complex coding or programming is required after installation. The repaired unit is ready for immediate use (plug-and-play).

Component-level repair replaces only the defective parts with genuine OEM components. This approach is not only cost-effective but also environmentally friendly, as it avoids producing an entirely new part.

How is the 98515-5RW8A control unit professionally repaired?

The repair process at Airbag24 is simple and transparent. After removal, the unopened control unit, along with the order form, is sent to Airbag24. There, a professional diagnosis is performed, followed by component-level repair—including clearing crash data—and a final functional test before insured return shipping.

Upon receipt, the control unit undergoes a thorough incoming inspection. Using state-of-the-art diagnostic tools, stored fault codes are read out, and the exact cause of the defect is identified—whether it’s stored crash data or a hardware issue.

The actual repair takes place at the component level. Specialized technicians open the unit, inspect the circuit board, and replace faulty components such as capacitors or sensors with new, genuine OEM parts. Stored crash data is securely and completely erased using specialized procedures.

Subsequently, the refurbished control unit undergoes a final functional test to ensure flawless operation. Each repair comes with a 12-month warranty.

What shipping options are available at Airbag24?
