4.8What is a Lexus GS S140 airbag control unit?
The Lexus GS S140 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, which is critical for safety.
This essential module, also known as the Airbag Control Module (ACM), coordinates the deployment of airbags and seatbelt pretensioners in the event of a collision. It is the "black box" of the safety system and precisely registers the severity and type of impact.
