Airbag control unit with part number 95400-1J450-1N

What is the function of Airbag Control Unit 95400-1J450-1N?

The component with part number 95400-1J450-1N is the central Airbag Control Unit for the SsangYong XLV X155 from model year 2016 onward. Its primary task is to monitor all sensors of the passive safety system and reliably deploy airbags and seatbelt pretensioners in the event of a crash.

As the brain of the Supplemental Restraint System (SRS), this control unit continuously processes data from acceleration and pressure sensors. Upon detecting a collision, it sends ignition signals to the appropriate restraint devices within milliseconds, providing optimal protection for occupants.

Manufactured for the Korean automaker SsangYong (KDM), the unit may incorporate components from specialized suppliers such as Bosch, Delphi, or Continental, renowned for their expertise in vehicle electronics. The precise functionality of this module is essential for vehicle safety.

What defects occur in 95400-1J450-1N?

The most common cause of failure for control unit 95400-1J450-1N is stored crash data following an accident, which the system locks out for safety reasons. Additionally, internal electronic faults, communication issues, or water damage can lead to complete system failure.

After a crash, the control unit stores non-erasable crash data—a safety measure designed to prevent reuse without professional inspection and repair. The result is a permanently illuminated SRS warning light and a deactivated airbag system.

Electronic malfunctions are another typical cause. These include board-level defects, faulty memory modules, or internal processor errors. Such faults can occur even without an accident and often manifest as a complete loss of communication with diagnostic equipment.

In repair contexts, related part numbers such as 95400-1J450 (without the suffix) or 95400-1J450-0K are also mentioned. These indicate different variants within the series, which frequently exhibit similar fault patterns.

How do you recognize a defect in the control unit?

A defect in Airbag Control Unit 95400-1J450-1N almost always manifests as a constantly lit or flashing airbag warning light (SRS light) on the instrument cluster. This is a clear indication that the airbags are disabled and would not deploy in the event of a crash.

The illuminated warning light is the system’s direct instruction to visit a qualified workshop. Never ignore this signal, as your vehicle’s passive safety is no longer guaranteed. Continuing to drive poses a significant safety risk.

In the workshop, the defect may further be confirmed by a lack of communication. When a technician attempts to read the control unit using diagnostic equipment, the connection fails or error codes appear, pointing to an internal, irreparable fault—requiring specialist repair.

How is control unit 95400-1J450-1N professionally repaired?

Professional repair at Airbag24 follows a systematic process. Following an initial assessment, stored crash data is erased, and electronic faults are addressed at the component level. The refurbished control unit undergoes rigorous testing and is then fully functional and ready for installation (plug-and-play), backed by 2 years’ statutory liability for defects.

Upon submission to Airbag24, the control unit first undergoes a comprehensive diagnosis. Using specialized software, fault memories are read, and the exact cause of the defect—whether it’s a crash-data lockout or an electronic fault—is determined.

This is followed by the actual repair. Stored crash data is completely and securely removed at the hardware level. If an electronic fault is present, defective components on the circuit board are identified and replaced by qualified technicians. Finally, the control unit is tested on a bench to ensure flawless operation across all systems.

The key advantage over an expensive new part is that the original vehicle coding remains intact. The repaired unit can be easily reinstalled without requiring time-consuming reprogramming at the workshop. You receive 2 years' statutory liability for defects on the repair performed.
