What is a Fiat 695 Abarth 312 airbag control unit?
The Fiat 695 Abarth 312 airbag control unit is the central safety unit in your vehicle, which activates all occupant restraint systems, such as airbags and seatbelt pretensioners, in the event of an accident. It continuously monitors sensors, stores relevant crash data, and ensures the proper functioning of all airbag system components.
This safety-relevant electronic module was developed specifically for the Fiat 695 Abarth Type 312. It forms the heart of the passive safety system and is responsible for the precise deployment of the airbags in an emergency.
Its main task is to monitor the crash sensors and rapidly analyze the severity of the impact. This ensures that the airbags are deployed only when necessary and with the correct intensity.
Why is the Fiat 695 Abarth 312 airbag control unit defective?
The Fiat 695 Abarth 312 airbag control unit may be defective due to age-related failure of internal electronic components, overvoltages or short circuits in the vehicle electrical system, or a permanent error due to the storage of crash data after an accident that requires a reset.
Internal errors in the control unit's hardware are a common cause of malfunctions. These can manifest themselves as unexplained warning lights or the complete failure of the airbag system.
Another reason for a defect is the deployment of the airbags in an impact. Crash data is permanently stored in the control unit, preventing reactivation without special repairs.
Electrical problems such as moisture ingress or faulty power supply can also cause permanent damage to the airbag control unit. A timely diagnosis is essential for safety.
