What is an Alfa Romeo Tonale 965 airbag control unit?

The Alfa Romeo Tonale 965 airbag control unit is the central safety module in the vehicle, coordinating the activation of all passive occupant protection systems in the event of an accident. It continuously monitors sensor data, stores important crash information, and is crucial for the safety of the occupants of the Alfa Romeo Tonale 965.

This electronic module, also known as the SRS control unit, receives signals from acceleration and pressure sensors. Based on this data, it decides whether and which airbags and seatbelt pretensioners need to be deployed.

The control unit also performs self-diagnosis and stores error codes in the event of system malfunctions. Proper functioning is essential, as it represents the main interface for all passive safety elements in the vehicle.

Why is the Alfa Romeo Tonale 965 airbag control unit defective?

The Alfa Romeo Tonale 965 airbag control unit often fails due to water damage, overvoltage, or age-related wear and tear of internal components.
