Mazda 3 BL ABS Pump Module Part No. 8V61-2C405-AE (2009-2013)

Yes. While the mechanical pump can be swapped, the electronic control module must be programmed and coded to your vehicle's specific VIN. This process ensures the unit can communicate correctly with the ECU and other safety systems like Dynamic Stability Control (DSC). You will typically need diagnostic software like FORScan or Mazda IDS to perform the module initialization and sensor calibration (such as the steering angle and brake pressure sensors) to clear any lingering "U-codes".

A failing 8V61-2C405-AE unit usually triggers a "triple light" warning (ABS, Traction Control, and Brake lights all on at once). The most frequent diagnostic trouble codes (DTCs) include: * C0020 / C2116: ABS Pump Motor Supply or Return Pump circuit malfunctions. * C1276 / 01276: ABS Hydraulic Pump (V64) internal malfunction. * 5DF0 / 5DF1: Hydraulic unit pump motor or connector faults, indicating the internal motor has likely seized or failed electrically.

Generally, yes. For the Mazda 3 BL series (2009–2013), part numbers 8V61-2C405-AE, 8V61-2C405-AF, and 8V61-2C405-AG are all part of the ATE MK61 system and are often interchangeable within the same engine types (1.6L, 2.0L, 2.3L). The letter at the end usually represents a minor production revision or a newer software version from the factory. However, always confirm that your original unit is an ATE MK61 and not the older MK60 series used in the BK model to ensure the wiring harness and hydraulic lines line up perfectly.
