What is an Alfa Romeo TZ2 105 airbag control unit?
The Alfa Romeo TZ2 105 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, essential for the safety of historic vehicles.
This specialized electronic module is designed to control the passive safety systems of the limited-edition Alfa Romeo TZ2 model produced between 1965 and 1967.
It acts as the brain of the airbag system, processes sensor signals and, if necessary, triggers the airbags and belt tensioners in a flash.
Why is the Alfa Romeo TZ2 105 airbag control unit defective?
The Alfa Romeo TZ2 105 airbag control unit often fails due to aging of the internal electronics, voltage fluctuations, or after an accident that stores crash data and requires a reset. Repair is then necessary to restore safety.
Internal hardware errors or a defective EEPROM memory can cause the control unit to stop functioning or display error messages.
Communication errors with other vehicle systems or the impact itself can also permanently damage or block the module, requiring comprehensive diagnosis and repair.
