Is your BL Series Mazda 3 (2009–2013) suffering from the common 'C0020' pump motor circuit failure? This Genuine OEM ABS Module (Part No: BFB4-437AZ-B) is the direct fix. High heat under the bonnet of the BL series often leads to internal module failure; our units are tested under load in Australia to ensure they won't fail when the engine bay gets hot.

Fault Code C0020 Pump Motor Fault—statistically the most common electronic failure in the BL series.
-

Fitment & Technical FAQ for Mazda 3 (2009 - 2013) Braking System Part #BFB4-437AZ-B
This is known as the "Trifecta" of lights on the Mazda 3 BL. It is almost always caused by Fault Code C0020 (ABS Pump Motor Control Circuit). This occurs when the internal motor brushes seize due to engine bay heat. Our units are "Hot-Tested" to ensure they perform perfectly even in extreme Australian summer temperatures.
Yes. Because the Mazda 3 BL shares the Ford C1 platform, part number 8V61-2C405-AF is identical to the unit used in the Ford Focus LV/LW. As long as the part number matches exactly, it is a direct fit. This makes it a highly versatile and reliable replacement option.
We strongly recommend an "Electronic Purge" or "Service Bleed" using a diagnostic tool. The ATE MK61 system in the BL series can trap air inside the secondary valve circuits that a traditional manual bleed cannot reach. A proper electronic bleed ensures a rock-solid brake pedal and full ABS functionality.
