What is a Subaru Outback Sport airbag control unit?
The Subaru Outback Sport airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag modules and seatbelt pretensioners in the vehicle to provide maximum protection.
This highly integrated electronic module, also known as the SRS control unit or airbag computer module, is essential for the vehicle's passive safety.
It continuously processes data from impact sensors and other systems in order to respond quickly and reliably in an emergency.
Why is the Subaru Outback Sport airbag control unit defective?
A Subaru Outback Sport airbag control unit can fail because it permanently stores crash data after an accident, causing it to lock up, or due to internal electronic failures such as a short circuit or aging. This often results in an illuminated airbag warning light and the need for professional repair or replacement.
Internal malfunctions or a lack of communication with the control unit are typical indicators of a defect.
Water damage or overvoltage can also irreparably damage the sensitive electronics of the control unit and make repairs necessary.
A failure means that the airbag system no longer deploys in an emergency, which is of high safety relevance and must be remedied immediately.
Common error codes for Subaru Outback Sport airbag control unit repair

- B1000 → Control unit communication error → Indicates that the airbag control unit is not communicating correctly with other systems, which often indicates an internal defect.
- Error 21 → Control Unit Defective → A specific Subaru internal error code that indicates a physical defect or internal malfunction of the airbag control unit itself.
