Product Features

The BVSN437AZC Mazda ABS hydraulic control unit is built to regulate braking pressure through the original hydraulic circuits of compatible Mazda 3 vehicles:

  • Directs hydraulic pressure adjustments during anti-lock braking events
  • Houses the ABS pump and its electrically operated drive motor
  • Incorporates an accumulator for the designated hydraulic pressure circuit
  • Contains a proportioning valve within the integrated brake assembly
  • Configured for select Mazda 3 applications lacking electronic stability control
  • Helps manage wheel slip when sudden braking demands increase
  • Maintains the specified interfaces for factory ABS wiring and brake lines

Application Notes

The BVSN437AZC is intended for select 2004–2009 Mazda 3 i, S, SP23, and Mazdaspeed configurations equipped with compatible 2.0L or 2.3L gasoline engines and an ABS system without stability control. Review the existing hydraulic assembly, brake line routing, electrical connections, and Mazda service procedures to determine the correct installation and bleeding requirements.

Always check the vehicle VIN, original ABS hydraulic unit identification, stability control configuration, hydraulic fitting positions, and factory bleeding specifications before installation.
