What is a Porsche 911 Targa 996 airbag control unit?
The Porsche 911 Targa 996 airbag control unit is the central safety unit of the Supplemental Restraint System (SRS), which detects accident situations and precisely activates all occupant restraint systems, such as airbags and seatbelt pretensioners. It stores important crash data and ensures the correct functioning of the entire airbag system.
This safety-critical module continuously monitors data from various crash sensors to ensure a quick and targeted response in an emergency. It is crucial for protecting vehicle occupants in the event of a collision.
A special feature of the Targa model is the integration of rollover protection functions into the control unit, which are specifically designed for the convertible roof and roll bar. Once triggered, the device stores crash data that can be read out for accident analysis.
