Product Features

The BVSN437AZ Mazda ABS hydraulic control unit is built to coordinate brake fluid distribution through the original anti-lock braking equipment of compatible Mazda 3 vehicles:

  • Controls hydraulic pressure changes during active anti-lock braking cycles
  • Features an integrated electric motor driving the ABS hydraulic pump
  • Uses an accumulator as part of the brake pressure management circuit
  • Contains a proportioning valve within the designated hydraulic assembly
  • Designed for specified Mazda 3 configurations without stability control
  • Helps limit wheel lockup when braking force increases suddenly
  • Connects with compatible factory brake lines and ABS control electronics

Application Notes

The BVSN437AZ is intended for select 2004–2009 Mazda 3 vehicles with 2.0L or 2.3L gasoline engines, including compatible i, S, SP23, and Mazdaspeed trims without stability control. Installation requires comparing the original hydraulic unit, brake pipe connections, electrical interface, and mounting arrangement, followed by the applicable ABS bleeding procedure.

Always confirm the vehicle VIN, original ABS assembly number, stability control configuration, hydraulic port arrangement, and Mazda-specific bleeding instructions before installation.
