Airbag control unit with part number 15195628

What does the airbag control unit 15195628 do?

The airbag control unit 15195628 controls the restraint system in the Chevrolet. It receives the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The evaluation takes place entirely inside the unit, because the reaction time in an impact is extremely short. At the same time, the control unit checks all connected components.

The unit stores faults in its memory and shows them via the airbag warning light. After an accident it also stores crash data and locks itself.

Why does the control unit 15195628 fail?

For the 15195628, the most common cause is crash data stored after an accident, even if no airbag was triggered. In addition, there are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes.

This crash data remains stored in the unit. A standard diagnostic tool cannot erase it, so the fault persists even after the unit has been read out.

Aged electronic components and cold solder joints can lead to loose contacts. Moisture and corrosion at the plug connectors disrupt signal transmission.

Voltage spikes arise, for example, from a weak battery or a jump start and can damage the electronics.

How can you tell that the 15195628 is defective?

A defect on the 15195628 shows up as an airbag warning light in the instrument cluster that stays on permanently or intermittently. In addition, there are fault messages, a missing connection between the diagnostic tool and the control unit, and a fault memory that cannot be cleared.

The signs are easy to match:

• Airbag warning light stays on permanently or intermittently
• Fault message in the instrument cluster
• Diagnostic tool gets no connection to the control unit
• Fault memory cannot be cleared

Airbags and seatbelt pretensioners may fail to trigger in an emergency while the fault persists. Therefore have the findings examined promptly.
