What is an Infiniti Q60 CV37 airbag control unit?

The Infiniti Q60 CV37 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensor data, stores important crash information, and ensures the proper deployment of all airbag modules and seatbelt pretensioners in the vehicle to provide optimal occupant protection.

This module, also known as the SRS Control Module, plays a crucial role in the passive safety of your Infiniti Q60 CV37.

It acts as the brain of the airbag system and is responsible for analyzing critical driving situations.
