What is a Renault 19 I airbag control unit?
The Renault 19 I airbag control unit is the central safety unit in your vehicle, precisely deploying the airbags and seatbelt pretensioners in the event of a collision. It continuously monitors crash sensors, stores relevant accident and system data, and thus ensures the functional safety of the occupant restraint systems.
This electronic module is crucial for safety by responding to collisions at lightning speed.
It acts as the brain of the passive safety system and is permanently installed in the vehicle, usually under the center console.
Why is the Renault 19 I airbag control unit defective?
