Restore your vehicle’s Supplemental Restraint System (SRS) with this OEM Mazda SRS Control Module, also known as the Airbag ECU or Restraint Control Module. This module is the central safety computer responsible for monitoring crash sensors and controlling the deployment of airbags and seatbelt pretensioners in the event of a collision.
The BRE7-57K30A module is designed to communicate with the vehicle’s safety network, process impact signals in real time, and ensure correct airbag system operation. It is commonly replaced after accident deployment, internal module failure, or when SRS warning lights remain active due to crash data stored in the unit.
This OEM unit is widely used across Mazda 3 platforms and must be correctly matched to the vehicle’s original part number for proper installation and SRS system functionality.
