Electronic Brake Control Module: Description and Operation
LOCATION
The Electronic Brake Control Module (EBCM) is located on the underside of the instrument panel on the driver's side.
NOTE: There is no serviceable or removable Programmable Read Only Memory (PROM). The EBCM must be replaced as an assembly.
FUNCTION
The EBCM monitors the speed of each wheel. If any wheel begins to approach lock-up and the brake switch is closed (brake pedal depressed), the
EBCM controls the motors and solenoids to reduce brake pressure to the wheel approaching lock-up. Once the wheel regains traction, brake
pressure is increased until the wheel age in begins to approach lock-up. This cycle repeats until either the vehicle comes to a stop, the brake pedal
is released or no wheels approach lock-up. Additionally, the EBCM monitors itself, each input (except the serial data link) and each output for
proper operation. If any system malfunction is detected, the EBCM will store a Diagnostic Trouble Code (DTC) in nonvolatile memory
NOTE: DTCs will not disappear if the battery is disconnected.
