Airbag control unit with part number 96305941

What is the function of the airbag control unit 96305941?

The airbag control unit with part number 96305941, also known as 96305941F, is the central control unit for the occupant restraint system (SRS) in the Daewoo Nubira J150. It processes signals from acceleration sensors and, in the event of a crash, precisely deploys the airbags and seatbelt pretensioners to protect occupants.

This unit is specifically designed for the Daewoo Nubira of the J150 series (1999–2002). Its primary task is continuous monitoring of all components of the restraint system. In the event of a collision, the control unit determines within milliseconds which safety systems need to be activated to minimize the risk of injury.

It serves as the “brain” of the airbag system and is essential for its proper functioning. A failure or malfunction in this component inevitably leads to deactivation of the entire system, posing a significant safety risk.

What defects occur in 96305941?

Typical defects of the control unit 96305941 include stored crash data after an accident that prevents further operation, as well as internal electronic faults that trigger error code B1111 (control unit defective). External factors such as water damage, corrosion, or mechanical stress can also cause failure.

One of the most common causes of failure is the storage of crash data. After an airbag deployment, the control unit locks itself for safety reasons and must be professionally reset. Simply clearing the fault memory is not sufficient here.

Another widespread issue is an internal hardware defect, often logged in the fault memory as error code B1111. This indicates faulty electronic components on the circuit board, damaged solder joints, or other internal malfunctions and cannot be resolved using conventional diagnostic tools.

Problems in peripheral components are also frequent, such as broken cables or corroded connectors. In particular, cables beneath the front seats can become damaged due to frequent adjustments, leading to communication errors with the control unit.

How do you recognize a defect in the control unit 96305941?

A defect in the airbag control unit 96305941 primarily manifests as a permanently illuminated or flashing SRS warning light on the instrument panel. Additionally, communication between the diagnostic tool and the control unit may cease, complicating troubleshooting.

The clearest indication is the activated airbag warning lamp. This signals that the Supplemental Restraint System (SRS) is inoperative and the airbags would not deploy in the event of a crash.

During diagnostics, the specific error code B1111 is often read, directly pointing to an internal defect in the control unit. This error code generally cannot be cleared with standard OBD devices and requires professional repair of the unit itself.

In some cases, the control unit becomes inaccessible to workshop diagnostics. When a technician attempts to read the fault memory, the connection fails—clear evidence of a severe internal fault in the module.

In which models is the control unit 96305941 installed?

Daewoo: Nubira J150 (model years 1999 to 2002)

How is the control unit 96305941 professionally repaired?

Professional repair at Airbag24 includes precise diagnostics using specialized software, targeted correction of the root cause—such as clearing crash data or replacing defective components on the circuit board—and a final functional test. We provide 2 years' statutory liability for defects on every repair.

After the removed control unit arrives at Airbag24, a detailed analysis is performed first. Using specialized diagnostic equipment, the fault memory is read to identify the exact source of the problem, whether it’s an internal hardware fault or stored crash data.

Subsequently, expert restoration takes place. Stored crash data is completely erased, restoring the unit to its original factory condition. For electronic defects, faulty components such as capacitors or other parts on the circuit board are replaced with high-quality new parts, and solder joints are reworked.

After repair, the control unit is thoroughly tested to ensure full functionality. This repair method is proven and safe, restoring the airbag system to full working order while saving you significantly compared to a new part (approximately €400).
