Symptom to Test Chart

There are times when a customer concern will not cause the REAR ABS warning light to illuminate or a code to be stored.

The symptom chart is intended to give the technician a starting point in resolving these types of concerns.

Please note that both the RED BRAKE warning light diagnosis procedure and the test drive are required prior to entering this section.
Failure to perform these procedures will greatly diminish the effectiveness of this method of diagnosis.
