Airbag control unit with part number 96806847

What is the function of Airbag Control Unit 96806847?

The airbag control unit with part number 96806847 is the central control module for the passive safety system in the first-generation Chevrolet Aveo (T200/T250). It processes data from crash sensors and ensures that, in the event of a collision, the airbags and seatbelt pretensioners are deployed precisely and promptly.

Technically speaking, it is an airbag ECU (Electronic Control Unit) that continuously monitors the entire restraint system. It verifies that all components—from sensors to airbag modules—are functioning properly.

In case of a malfunction or after a crash, the control unit reports an error, indicated by the illumination of the airbag warning light on the dashboard.

Why does control unit 96806847 fail?

The most common causes of failure for control unit 96806847 include stored crash data following an accident, which locks the unit, as well as internal electronic faults. These may involve defective SMD components, faulty capacitors, short circuits on the circuit board, or damaged trace connections that impair functionality.

After an airbag deployment, the control unit stores so‑called crash data. This data remains permanently saved in memory and, for safety reasons, prevents reuse without professional inspection and reset.

Besides crash data, purely electronic component failures can also occur. Specialized repair shops often identify defective microcomponents (SMD parts), power supply issues, or faulty memory chips (EEPROM/Flash) during diagnostics—each potentially leading to complete system failure.

It’s important to note that this control unit is known under various part numbers. Compatible and interchangeable alternatives include, among others, 96808099, 5WY67067-95160, 96806848, and 5WY67068-95160.

How do you recognize a defect in control unit 96806847?

A defect in control unit 96806847 almost always manifests as a persistently illuminated airbag warning light on the dashboard. Another clear indication is that fault codes stored in the error memory—especially after a crash—cannot be cleared using standard workshop diagnostic equipment.

The most noticeable symptom is the active airbag warning light, which fails to extinguish even after restarting the engine. This signals a serious issue within the safety system that requires immediate attention.

In the workshop, the defect often becomes apparent when attempts to read and erase the error memory fail. The diagnostic tool typically reports errors such as “Crash data stored” or “Internal control unit error,” which cannot be reset.

In which vehicles is airbag control unit 96806847 installed?

The airbag control unit with part number 96806847, along with its compatible variants, is specifically designed for the first-generation Chevrolet Aveo. This applies to the T200 and T250 model series produced roughly between 2006 and 2011.

At Airbag24, we repair this control unit for the following model:

Chevrolet Aveo 1st Generation (model years 2006–2011)

Accurate identification via the part number is crucial, as identical units bearing numbers like 96808099, 96806848, or 5WY67067-95160 may also be installed in the same vehicle model.

How is control unit 96806847 professionally repaired?

Professional repair at Airbag24 begins with a thorough incoming inspection and fault diagnosis. Depending on the findings, defective electronic components on the circuit board are replaced, or stored crash data is securely erased using specialized hardware. A final functional test guarantees full operability.

Upon submission to Airbag24, each control unit undergoes a standardized process. First, the error memory is read to distinguish between pure crash data storage and an actual hardware fault.

The repair itself takes place at the component level. Our technicians replace defective SMD components, repair damaged power supply or communication pathways, and, if necessary, reset the memory chip (EEPROM/Flash). Crash data is only erased when technically safe and legally permissible.

Following restoration, the control unit is tested on a dedicated test bench to ensure it functions like new and communicates flawlessly with the vehicle. We provide 2 years' statutory liability for defects on every repair.
