ABS Control Module - 2002 Corvette C5 LS1

The 2002 Chevrolet Corvette C5 utilizes a Bosch 5.3 ABS control module, with primary OEM reference 12216524 or AC Delco service replacement 19122449. This electronic brake control module (EBCM) mounts directly to the hydraulic modulator and requires precise VIN programming when replaced. Interchange compatibility spans 2001-2004 Corvettes; earlier 1997-2000 models utilize different connector pinouts despite similar appearances, necessitating recalibration or hardware swaps. When sourcing from salvage yards, inspect connector pins for corrosion caused by brake fluid wicking—a common failure mode where fluid contaminates the internal circuit board through the integral pressure sensor port. Verify the casting number 0 265 950 002 stamped on the aluminum housing to confirm late-C5 specification. Installation demands a Tech 2 or equivalent scan tool to marry the module to the PCM, followed by a thorough brake bleed sequence including the electronic brake module motor activation routine. Avoid units showing physical damage to the hydraulic valve stems or evidence of previous soldering attempts on the circuit board connector, as these indicate irreparable internal faults.
