Airbag control unit with part number 96305941F

What is the function of the airbag control unit 96305941F?

The airbag control unit with part number 96305941F is an original Daewoo safety component, known under the manufacturer’s reference DFHPA3UPG. As the central control unit of the restraint system, it processes signals from crash sensors and, in the event of a serious accident, precisely deploys the airbags and seatbelt pretensioners to protect occupants.

This control unit is a central and vital component of the vehicle’s safety system. It continuously collects and analyzes data from acceleration and angular velocity sensors. If the system detects a collision exceeding a predefined threshold, it sends ignition pulses to the corresponding airbag modules and seatbelt pretensioners within milliseconds.

After professional repair—during which all relevant data are reset and electronic faults are corrected—the repaired control unit functions like new, ensuring the system’s full protective capability.

Why does the control unit 96305941F fail?

The most common cause of failure for the control unit 96305941F is the storage of crash data following an airbag deployment. Additional defects arise from physical damage such as broken wiring, incorrect wiring, loose connectors, or water damage that leads to internal electronic malfunctions.

Following a traffic accident in which airbags have deployed, the control unit locks internally and permanently stores the crash data. This lock serves as a safety measure to prevent further operation. In such cases, the device must be professionally reset to restore the safety system’s functionality. If the unit has been physically damaged beyond repair by the accident itself, replacement is mandatory.

Other sources of failure are electronic in nature. These include defective wiring connecting the control unit to the sensors or airbags, as well as improper wiring of SRS components (Supplemental Restraint System). Loose or corrosion‑damaged connectors can also impair functionality and trigger error messages. Less frequently, water damage or spontaneous electronic faults on the circuit board are responsible.

How do you recognize a defect in the 96305941F?

A defect in the control unit 96305941F primarily manifests as a constantly illuminated airbag warning light on the instrument panel. Additionally, specific fault codes—such as the well‑known B1000 code—can be read from the fault memory. In some cases, communication with the diagnostic tool may no longer be possible.

The most obvious sign is the red airbag warning light. After starting the vehicle, it not only flashes briefly but remains steadily lit, indicating a malfunction in the restraint system that requires immediate inspection.

During a workshop diagnosis, specific fault codes can be retrieved from the control unit’s fault memory. A typical entry for this module is fault code B1000, which points to an internal control unit error. Precise analysis of these codes is crucial for accurately identifying the source of the problem.

In which vehicles is the control unit 96305941F installed?

The airbag control unit 96305941F is specifically installed in Daewoo vehicles. At Airbag24, we repair this module for Daewoo Nubira J100 models from model years 1997–1999, as well as for the station wagon variants Daewoo Nubira Wagon J100 and Daewoo Nubira Wagon J150.

Compatibility is limited to these specific models. At Airbag24, we ensure that repairs are precisely tailored to the technical requirements of these vehicles to guarantee flawless operation.

How is the control unit 96305941F professionally repaired?

At Airbag24, repairing the control unit 96305941F begins with a precise diagnosis through reading the fault memory. Subsequently, stored crash data are erased, known fault codes such as B1000 are resolved, defective electronic components are repaired, and the unit is restored to its factory settings.

Upon receipt of the control unit at Airbag24, a comprehensive analysis is first conducted. Using a specialized diagnostic tool, the fault memory is read to pinpoint the defect and determine whether repair is feasible and economically viable.

The core of the repair involves erasing crash data and correcting known fault codes. Defective components on the circuit board are identified and expertly replaced. Finally, a workshop reset is performed, calibrating the control unit back to its original factory condition. We provide 2 years’ statutory liability for defects on all repairs carried out.

Important for safe removal and installation: Always disconnect the vehicle battery at least 20 minutes before starting work to ensure the system is fully discharged. The battery may only be reconnected once the control unit has been completely and securely reinstalled.
