GM ABS/ETS Service: EBCM/EBTCM & Front Wheel Speed Sensor Removal (5E2-269)

This is page 5E2-269 from a GM factory service manual section covering the Antilock Brake System (ABS) and Enhanced Traction System (ETS). The page contains three service procedures. First, it concludes the Brake Solenoid Valve (ABS) removal procedure with Figure 13, an exploded diagram whose legend identifies the brake solenoid valve Torx bolt, solenoid valve, lip seal, brake modulator, and harness connector; it notes disconnecting the ABS brake motor pack 6-way connector, brake fluid level indicator sensor connector, and two solenoid valve connectors, with an Important note to bleed the system per Section 5. Second, it details removal and installation of the Electronic Brake Control Module/Electronic Brake Traction Control Module (EBCM/EBTCM): the module is released from its bracket via pressure tabs and its electrical connectors disconnected, then reinstalled in reverse. Figure 14 illustrates the module mounting near the I/P harness, mounting housing, and Electronic Brake Control Relay. Third, the page begins the Front Wheel Speed Sensor removal procedure (Figures 15 and 16), requiring special tool J 38764, warning that the front sensor is serviceable only as an assembly (the harness pigtail cannot be serviced separately), and directing the technician to raise the vehicle, remove the tire and wheel, and disconnect the sensor connector.
