Airbag control unit with part number 96442702

What is the function of the airbag control unit 96442702?

The airbag control unit with part number 96442702, also known as the SRS module, is the central control unit for the entire occupant protection system. It is responsible for evaluating signals from crash sensors and, in the event of a collision, precisely and reliably deploying the airbags and seatbelt pretensioners.

This unit continuously monitors all connected components, such as sensors, airbags, and seatbelt pretensioners. In case of a malfunction or after deployment, the device stores corresponding fault codes and activates the airbag warning light to alert the driver to a potential compromise in system safety. It is specifically designed for use in certain Chevrolet and Daewoo models.

Why does the control unit 96442702 fail?

A primary reason for the failure of control unit 96442702 is the storage of crash data following an accident. This data permanently locks the unit’s functionality and cannot be cleared using conventional diagnostic tools. Other causes include internal electronic malfunctions or defects in cable connections.

After a collision, the module becomes internally locked to prevent unintended re‑deployment. This condition is often indicated by the persistent fault code B1111 (control unit defective). Simply clearing the fault memory does not resolve the underlying issue, as the crash information remains firmly embedded in the device’s memory.

In addition to accident‑induced lockouts, electrical disturbances, mechanical stress from vibrations, seat adjustments, and moisture can also lead to failures. Cable breaks—such as on the brown/red‑yellow wire—or faulty components like capacitors and sensors on the circuit board are likewise common sources of trouble.

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

The most obvious symptom of a defect in control unit 96442702 is a persistently illuminated airbag warning light (SRS lamp) on the instrument panel. Additionally, the fault code B1111 (control unit defective) is often stored in the fault memory and cannot be permanently erased.

The airbag indicator light fails to turn off after starting the vehicle, signaling a serious malfunction in the restraint system. In this state, the system is typically disabled and offers no protection in the event of a crash.

In the workshop, the defect often manifests when attempts to clear the fault memory using an OBD2 scanner fail. The B1111 error code immediately reappears because the root cause—such as stored crash data or an internal hardware fault—remains unresolved.

In which vehicles is control unit 96442702 installed?

The airbag control unit 96442702 is used in specific models of Chevrolet and Daewoo brands. These include, among others, the second-generation Chevrolet Aveo as well as various Daewoo models such as the Chairman H, BH 117i, and Lemans T100.

How does the repair process work at Airbag24?

The repair of control unit 96442702 at Airbag24 includes a professional diagnosis, elimination of the root cause—such as resetting crash data—replacement of defective components, and a final functional test. Each repair comes with 2 years' statutory liability for defects.

Upon submission to Airbag24, the control unit undergoes a thorough initial inspection. Technicians pinpoint the source of the fault using specialized testing equipment, whether it’s stored crash data or a defect on the circuit board.

The core of the repair involves completely erasing crash data using advanced software and restoring the unit to its factory settings. If electronic components such as sensors or capacitors are defective, they are expertly replaced. Damaged cable connections are also repaired.

Subsequently, the repaired control unit undergoes a rigorous functional test to ensure all fault codes have been cleared and the module communicates flawlessly once again. Only after passing this test is it approved for return shipment.
