Airbag control unit with part number 9516095237840

What is the function of the airbag control unit 9516095237840?

The airbag control unit with part number 9516095237840 is the central control module for the occupant protection system, specifically designed for the first-generation Chevrolet Aveo (T200/T250). Its primary task is to process signals from acceleration and crash sensors and, in the event of a collision, to deploy the airbags and seatbelt pretensioners precisely and promptly.

As the “brain” of the safety system, the control unit continuously monitors all connected components, from the sensors to the airbag igniters. It ensures that the entire system remains operational at all times.

In case of a system malfunction or internal defect, the unit activates the airbag warning light (SRS light) on the instrument panel. This alerts the driver to a critical safety issue, as the protective function of the airbags can no longer be guaranteed.

Why does control unit 9516095237840 fail?

The most common cause of failure for control unit 9516095237840 is crash data stored internally after an accident. This data prevents the unit from functioning further and cannot be cleared using workshop diagnostic tools. Other defects include internal electronic malfunctions, communication issues with the vehicle, or secondary damage caused by water ingress.

After an accident—even minor collisions—the control unit writes so‑called crash data into its internal memory. This is a safety measure designed to prevent reuse without professional inspection. The result is a persistent error message and deactivation of the airbag system.

Internal electronic faults are another frequent cause. Components on the circuit board may fail due to aging, voltage spikes, or thermal stress, leading to total failure or communication problems with the vehicle.

In some cases, other part numbers such as 7088906 or 96806848 may also appear on the unit. These are often technically related variants that exhibit similar fault patterns.

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

A defect in control unit 9516095237840 primarily manifests as a permanently illuminated or intermittently flashing airbag warning light (SRS light) on the instrument panel. Often, fault codes stored in the error memory cannot be cleared, or the control unit becomes unreachable by diagnostic equipment, indicating a loss of communication.

The most obvious symptom is the active airbag warning light. It fails to turn off after starting the vehicle, signaling that the restraint system is not functioning. This poses a significant safety risk and results in failure during the mandatory vehicle inspection (HU).

Another clear indication is when specific error messages—such as “internal error” or “crash data stored”—can be read via diagnostic equipment but cannot be permanently erased. The fault reappears immediately.

In more severe cases, there is no communication between the diagnostic tool and the airbag control unit. The unit does not respond to requests, making further diagnosis at the workshop impossible.

In which vehicles is control unit 9516095237840 installed?

The airbag control unit with part number 9516095237840 was specifically designed for models manufactured by Chevrolet. At Airbag24, we repair this control unit and its variants primarily for the first-generation Chevrolet Aveo, also known under the model designations T200 or T250.

Chevrolet Aveo, first generation (model series T200/T250, years of manufacture 2006–2011)

How does the repair process work at Airbag24?

The repair process at Airbag24 follows a proven, systematic procedure. After receiving the removed control unit, our technicians conduct a thorough incoming inspection to precisely analyze the fault. Next, crash data is deleted, and defective electronic components on the circuit board are replaced. A final test confirms full functionality.

Once the control unit arrives at Airbag24, it undergoes a professional diagnosis. During this phase, the error memory is read, and the electronic components on the circuit board are examined to identify the exact cause of the fault.

The actual restoration focuses on eliminating the root cause. This includes professionally erasing stored crash data, repairing internal electronics, and replacing faulty components if necessary. The unit is then returned to its original factory condition.

Finally, each control unit undergoes a thorough functional test to verify successful repair. Of course, we provide a 12-month warranty on all repairs.

What shipping options does Airbag24 offer?

Airbag24 offers flexible and secure shipping options. You can either return the package yourself free of charge or arrange a convenient UPS pickup at your preferred location.
