2013-2014 BRZ 6MT VDC Hydraulic Unit and ABS Module Identification

Verified only for the narrowed manual Subaru service branch: 27596CA012 -> 27596CA013. The checked automatic relationship 27596CA042 -> 27596CA043 and separate 27596CA050 identity are not manual substitutes. No supersession or interchange is asserted from donor labels 27536CA000/27536CA002 to the Subaru service assembly, between manual and automatic, or between Subaru and Toyota/Scion identities. A service replacement does not erase VIN/build, transmission, connector, port, calibration or contents checks.

Start with both VINs/builds and a qualified ABS/VSC fault scan; preserve ZN6-0025 ownership of wheel-speed sensor, harness and reluctor diagnosis, ZN6-0037 ownership of master-cylinder/booster diagnosis and ZN6-0044 ownership of standard-versus-Brembo brake service. Require confirmation of US 2013-2014 BRZ, 6MT, Base/High equipment and service assembly 27596CA012 or 27596CA013. Require readable photos of the Subaru service and electronic labels, connector keying/pins, pump motor, actuator body, bracket, every hydraulic port and line orientation, and every included fastener. Require donor VIN/build/transmission, stored ABS/VSC DTCs before removal, test method, warranty and returns. Reject flood, water, fire or collision exposure; cracked/impact-damaged castings; bent, cross-threaded, uncapped, contaminated or corroded ports; contaminated fluid; corroded pins; broken latches; cut wiring; or unexplained opening/mixed halves. A warning lamp or wheel-sensor code does not condemn the actuator. The checked BRZ service information requires VSC centering after brake-actuator replacement, including zeroing the yaw/G and steering-angle sensors on a level surface with Subaru-compatible scan equipment; bleeding is required after actuator removal/installation. A vendor's no-reload claim applies only to repair and return of the unchanged original unit and does not authorize skipping Subaru replacement procedures. Opening the hydraulic circuit requires clean specified fluid, paint protection, sealed ports, every line returned to its original position, qualified bleeding and post-repair DTC/ABS/VSC functional verification. No bypass, delete or calibration-hack instructions.

The checked alternative is repair and return of the vehicle's original BRZ ABS/VSC unit. Retaining the unchanged original may preserve its programming, but no-reload/no-calibration language is a vendor claim limited to that repair work order and does not prove donor compatibility or authorize skipping post-repair scans and functional checks. No checked aftermarket path proves manual/automatic, Subaru/Toyota/Scion, later-BRZ, standard/Brembo interchange, a universal actuator, an ABS/VSC bypass or a no-bleed hydraulic shortcut.

US 2013-2014 Subaru BRZ 6MT only, service 27596CA012 -> 27596CA013. Automatic, FR-S/86 cross-badge, 2015-and-later and Brembo/conversion interchange are not claimed. Match both VINs/builds, transmission, service/electronic labels, connector, ports and contents after diagnosis. Replacement requires Subaru-compatible VSC centering/zero-point work where directed. Opening hydraulics requires contamination-controlled qualified brake service, correct line placement, bleeding and post-repair ABS/VSC verification. Seller stock and prices are dated observations.
