Initial Inspection and Diagnostic Overview

SYSTEM DIAGNOSIS
The anti-lock system diagnosis involves three basic procedures. The first procedure requires the observation of the indicator lights on the instrument panel and their display sequence. The second is a visual inspection of system components for low fluid levels, leak points, or visible damage. The third involves the use of the Diagnostic Readout Box II (DRB II) to check the operation and locate a malfunctioning component.
