Airbag control unit with part number 96 534 479

What is the function of Airbag Control Unit 96 534 479?

The airbag control unit with part number 96 534 479 is the central control module of the Supplemental Restraint System (SRS) in the Daewoo Lanos T100. As an OEM component from Bosch, it processes signals from crash sensors and precisely deploys airbags and seatbelt pretensioners in the event of a collision.

This component continuously monitors all safety‑related components of the restraint system, including front and side airbags, seatbelt pretensioners, as well as their associated sensors and wiring. Its proper operation is critical for occupant safety.

The control unit is specifically designed for the Daewoo Lanos T100 series (model years 1997–2004), ensuring compatibility with vehicle‑specific systems.

Why does control unit 96 534 479 fail?

The most common cause of failure for control unit 96 534 479 is the storage of crash data after a collision. This data permanently disables the unit’s functionality. Other causes include internal electronic faults, indicated by error codes such as B1111 or 65535, which point to a defect within the device itself.

Following a crash in which airbags or seatbelt pretensioners have deployed, the unit writes a permanent crash record into its internal memory. This entry locks the system to prevent unintended activation and must be professionally erased to restore full functionality.

Non‑collision‑related defects can also occur, such as internal failures caused by voltage spikes, insufficient supply voltage, or age‑related wear of electronic components on the circuit board. These issues result in diagnostic errors B1111 or 65535, directly indicating an internal control unit fault.

In some cases, external problems—such as loose cable connections, for example at the seatbelt pretensioners or beneath the seats—can trigger malfunctions in the control unit and illuminate the warning light.

Similar repair procedures apply to functionally related Daewoo part numbers, such as 96217003.

How do you recognize a defect in control unit 96 534 479?

The clearest symptom is a continuously illuminated or flashing SRS airbag warning light on the instrument cluster. Often, the fault memory cannot be cleared, and diagnostic tools display error codes like B1111 or 65535, confirming an internal control unit malfunction.

The airbag indicator light signals that the entire restraint system is disabled. In the event of another accident, neither airbags nor seatbelt pretensioners will deploy, posing a significant safety risk.

A diagnosis via the OBD interface reveals error “65535 – Control unit defective” or “B1111 – Internal error.” These specific codes directly indicate a problem within the control unit and cannot be resolved simply by clearing the fault memory.

In which vehicles is control unit 96 534 479 installed?

The airbag control unit 96 534 479 was specifically developed by OEM manufacturer Bosch for a particular vehicle series. It is used exclusively in Daewoo models, especially the first‑generation Lanos.

At Airbag24, we repair control units with part number 96 534 479 for the following model:

Daewoo Lanos T100 (1997–2004)

How is control unit 96 534 479 professionally repaired?

Professional repair restores control unit 96 534 479 completely to factory condition. After removal and shipment to Airbag24, stored crash data is erased, the fault memory reset, and any defective electronic components on the circuit board replaced if necessary. The unit is then fully functional again.

Removal in the Daewoo Lanos typically takes place in the center console beneath the handbrake lever. Before performing any work on the airbag system, the vehicle battery must be disconnected and a waiting period observed to prevent accidental deployment.

Upon receipt at Airbag24, technicians conduct a thorough analysis. Using specialized hardware and software, crash data is removed from the memory chip, and internal faults are corrected. This process restores the original functionality, eliminating the need to purchase an expensive new part.

After repair, the control unit is returned ready for installation. No re‑coding or reprogramming is required. We provide 2 years' statutory liability for defects on the completed repair.

What are the benefits of repairing 96 534 479?

The key advantage of repair is substantial cost savings—up to 90% compared to purchasing a new unit, which can cost up to €750. Repair offers a technically equivalent yet economically smart solution that preserves the vehicle’s original component.

Since the original control unit is retained and merely reset, there’s no need for time-consuming and costly programming or coding work at the workshop. Once installed, the repaired unit functions perfectly right away (plug-and-play).

Moreover, this repair is a sustainable alternative, as it helps avoid electronic waste and conserves valuable resources. With 2 years’ statutory liability for defects on the repair, it provides a safe and reliable solution.
