Symptom Diagnosis Chart

Get an understanding of the trouble symptoms and check according to the inspection procedure chart.

CAUTION:
1. If steering movements are made when driving at high speed, or when driving on road surfaces with low frictional resistance, or when passing over bumps, the ABS may operate even though sudden braking has not occurred. Because of this, determine if the problem occurred while driving under these conditions.
2. During ABS operation, changes in the feeling of the brake pedal (vibration) may occur or pedal may not be able to be depressed. Such changes are due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking, and should be considered normal.
