Lincoln Navigator: Power Brake Actuation / Power Brake System - Overview. Description and Operation
Electric Brake Boost
Overview
The power assisted brake system utilizes an EBB . The EBB is an
integrated function of the ABS / HCU assembly and is controlled by the
ABS module. The ABS / HCU combines the functions of a conventional
vacuum booster and ABS module. The ABS module controls and monitors the
EBB function and sets Diagnostic Trouble Codes (DTCs) when a fault is
present in the system. The IPC illuminates the red brake warning
indicator and displays a message in the message center when a fault is
present.
