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.
Preliminary Inspection
Visually inspect the CV joints, housing, boots, and clamps for obvious signs of mechanical damage.
