BEGIN DIAGNOSIS
Failure of a mechanical brake component may not cause the ABS warning indicator to illuminate or a diagnostic trouble code (DTC) to be stored. The symptom chart is a starting point to begin diagnosis of these concerns. The System Pre-Check must be performed prior to consulting the symptom chart to verify other diagnostic trouble codes (DTCs) have not been set, and to maximize the effectiveness of this method of diagnosis.

NOTE: Perform indicated pinpoint test or drive test steps only. do not perform other steps (although within the test details/results/actions box, you may appear to be directed to do so). Always return to the symptom chart if no resolution is reached by performing a particular test step.
