Here’s an image of a Toyota ABS brake actuator assembly—commonly referred to as an ''ABS pump''—similar to the one used in Alphard/Vellfire models, including the AGH30 generation.

What Is the ''ABS Pump'' on an Alphard AGH30?

The ABS pump—or more precisely, the ABS brake actuator assembly—is a crucial hydraulic and electronic component in the vehicle’s Anti-lock Braking System (ABS). It:

• Modulates brake pressure in real time during braking to prevent wheel lock-up.
• Works via an integrated hydraulic unit paired with an electric motor and electronic valves to control fluid flow during ABS activation.
• Houses sensors and an electronic control module that interfaces with the vehicle’s ECU for feedback and diagnostics.  

This assembly ensures safe and stable braking performance, especially under hard braking or slippery conditions.

About the ''6A'' Pump Code

On platforms like Facebook or JDM parts listings, you may see codes such as 3A, 6A, 9A, 4G, 7G, etc., used in reference to ABS pump units for models like the Alphard/Vellfire AGH30. These are often internal variant or production codes that identify specific configurations or revisions of the ABS pump assembly. For example:

• Sales listings mention ''ABS Pump Code: 3A 6A 9A 0G 4G 7G'' as identifiers for different units  .
• Listings on Facebook groups or marketplaces reference these codes for compatibility and ordering purposes  .

However, there isn’t any publicly available documentation clearly defining what each code (like ''6A'') means in terms of hardware differences. These codes are likely used by parts suppliers or dismantlers for matching specific versions or revisions of the ABS actuator to a particular vehicle specification.
