Airbag control unit with part number 96417796

What is the function of Airbag Control Unit 96417796?

The airbag control unit with part number 96417796 is the central control module for the occupant safety system (SRS) in vehicles such as the Daewoo Tacuma U100. It continuously processes data from collision and acceleration sensors and, in the event of a crash, determines whether and which airbags or seatbelt pretensioners should be deployed to protect occupants.

As the “brain” of the safety system, this unit is responsible for monitoring all SRS components. It ensures that the system remains operational at all times and reports malfunctions via the airbag warning light on the dashboard.

The unit communicates with other vehicle control modules to ensure precise deployment. Therefore, its proper functioning is essential for the vehicle’s passive safety.

Why does control unit 96417796 fail?

Failures in control unit 96417796 often result from stored crash data after an accident, which locks the device. Other major causes include internal electronic faults leading to malfunctions, as well as physical damage caused by water ingress, resulting in corrosion on connectors and circuit boards. Overvoltage can also harm the sensitive electronics.

A common cause is the retention of crash data following a collision. Even after bodywork repairs, the control unit may remain internally locked and require professional reset.

Internal electronic defects—such as issues with capacitors or the main circuit board—are another frequent culprit. These malfunctions generate persistent error messages that cannot be cleared, disabling the entire airbag system.

Less common but equally critical are water-related damages. Moisture entering areas like the footwell or center console leads to corrosion on connectors and circuit boards, potentially causing complete failure.

This control unit is also known under equivalent part numbers 96282803 and 96287495, which are technically identical and may exhibit the same fault patterns.

How do you recognize a defective control unit 96417796?

A defect in control unit 96417796 primarily manifests as a permanently illuminated or flashing SRS/airbag warning light on the instrument cluster. Often, standard diagnostic tools can no longer read the unit, or specific error codes such as B1111, 65535, or 93F9 (internal error) appear and persist without being cleared.

The most obvious sign is the activated airbag warning light. This indicates a malfunction in the safety system and remains lit even after restarting the engine, constituting a significant defect during vehicle inspection.

Another clear symptom is the lack of communication with the control unit. Workshops cannot establish a connection via the OBD interface, complicating accurate diagnosis. In some cases, general CAN-bus errors are also reported.

The fault memory frequently stores non‑erasable error codes. Typical examples include codes B1111 and 65535, both pointing to an internal fault within the control unit, or code 93F9. Standard diagnostic tools commonly used in independent workshops cannot resolve these errors.

In which vehicles is control unit 96417796 installed?

The airbag control unit with part number 96417796, along with its compatible variants 96282803 and 96287495, is primarily fitted in models from Daewoo and Chevrolet. Notably, this includes the Daewoo Tacuma U100 throughout its production run, as well as the Chevrolet Rezzo, built on the same platform.

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

Daewoo: Tacuma U100 (model years 2000–2011)

Chevrolet: Rezzo (U100, e.g., model year 2007, 2.0-liter engine)

Due to the interchangeability of part numbers, it is crucial to verify compatibility. The aforementioned models cover the primary application range of this control unit module.

How is control unit 96417796 repaired?

Professional repair at Airbag24 involves diagnosis, correction of the root cause, and a final functional test. After removal and shipment of the unit, stored crash data is erased using specialized software, defective electronic components are replaced, and the control unit is reprogrammed to restore full functionality.

The process begins with the careful removal of the control unit from the vehicle, typically located in the center console beneath the handbrake lever or in the footwell. It is important to disconnect the vehicle battery beforehand and allow a waiting period of at least 10 to 30 minutes.

After sending the unit to Airbag24, a detailed analysis is performed to identify the exact cause of the fault. Technicians address any identified issues, whether by resetting crash data, replacing defective capacitors, or repairing the circuit board.

The control unit is then thoroughly tested to ensure it communicates flawlessly with the vehicle and properly manages all safety functions. Following disassembly, we recommend treating the connectors with contact spray and finally clearing the fault memory using an appropriate diagnostic tool.

We provide 2 years' statutory liability for defects on every repair.
