What is an Alfa Romeo 90 162 airbag control unit?
The Alfa Romeo 90 162 airbag control unit is the central electronic module in the vehicle responsible for the safety of the occupants in the event of a collision. It continuously monitors the function of the airbag system, receives signals from crash sensors, and precisely deploys the airbags and seatbelt pretensioners when necessary to prevent serious injuries.
This essential component coordinates all safety functions that protect the lives of vehicle occupants in the event of an accident. It is the "thinking center" of the passive safety system in your Alfa Romeo 90.
An intact control unit is essential because it ensures the reliability and functionality of the entire airbag system.
Why is the Alfa Romeo 90 162 airbag control unit defective?
An Alfa Romeo 90 162 airbag control unit can fail due to aging electronic components, overvoltages in the vehicle electrical system, or internal software errors. Because it's a highly sensitive safety component, even a minor malfunction can lead to a failure of the airbag system, requiring immediate repair of the Alfa Romeo 90 162 airbag control unit.
Common causes include internal short circuits, age-related material fatigue of the circuit boards, or even water damage caused by moisture penetration. Such defects can cause the airbag warning light in the dashboard to stay permanently illuminated.
A failure can also be caused by a faulty power supply or unacceptable voltage fluctuations. A professional diagnosis is always the first step if you suspect a defective airbag control unit.
