Anti-Lock Brake Control Module

2011 Mazda 3 Mazdaspeed, 2.3 3SECTION Anti-Lock Brake Control Module
WARNING: This page is about a different car, the 2002 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The 4x2 service replacement module cannot be interchanged with the 4x4 module. The service replacement 4x4 module is interchangeable with the 4x2 module.

The anti-lock brake control module is mounted to the HCU.

It is an on-board diagnostic, non-repairable unit consisting of two microprocessors and the necessary circuitry for their operation. The anti-lock brake control module monitors system operation during normal driving as well as during anti-lock braking.

Anti-lock brake module operation is as follows:

  • Under normal driving conditions, the microprocessor produces short test pulses to the solenoid valves that check the electrical system without any mechanical reaction.
  • Impending wheel lock conditions trigger signals from the anti-lock brake control module that open and close the appropriate solenoid valves. This results in moderate pulsations in the brake pedal.
  • The anti-lock brake module used in 4x4 application includes a G-sensor. It detects vehicle movement during a brake lockup event that is transferred to other wheels through the powertrain.

    During normal braking, the brake pedal feel is identical to a standard brake system.

    Most faults that occur in the anti-lock brake system will be stored as a Diagnostic Trouble Code (DTC) in the keep-alive memory of the anti-lock brake control module. The DTCs can be retrieved by following the on-board diagnostic procedures.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
