What is a Toyota Etios Cross airbag control unit?
The Toyota Etios Cross 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 immediate deployment of the airbag modules and seatbelt pretensioners for maximum occupant safety.
It is a highly sensitive electronic module that continuously monitors the status of the passive safety system.
In the event of an impact, the control unit analyzes the sensor data at lightning speed to initiate the necessary safety measures.
