Electronic Brake Control Module: Description and Operation
EBCM

ELECTRONIC BRAKE CONTROL MODULE (EBCM)

Notice:  There is no serviceable or removable EEPROM. The EBCM must be replaced as an assembly.

The EBCM is attached to the hydraulic unit in the engine compartment. The controlling element of ABS 5.3 is a microprocessor- based EBCM. Inputs
to the system include the four wheel speed sensors, the stoplamp switch, the ignition switch, and the unswitched battery voltage. There is an output to
a bi-directional serial data link, located in pin K of Data Link Connector (DLC) for service diagnostic tools and assembly plant testing.
The EBCM monitors the speed of each wheel. If any wheel begins to approach lockup and the brake switch is closed (brake pedal depressed), the
EBCM controls the solenoids to reduce brake pressure to the wheel approaching lockup. Once the wheel regains traction, brake pressure is increased
until the wheel again begins to approach lockup. This cycle repeats until either the vehicle comes to a stop, the brake pedal is released, or no wheels
approach lockup.
Additionally, the EBCM monitors itself, each input (except the serial data link), and each output for proper operation. If it detects any system
malfunction, the EBCM will store a DTC in nonvolatile memory (EEPROM) (DTCs will not disappear if the battery is disconnected).
