ABS – Troubleshooting35B-11
3. INSPECTION CHART FOR TROUBLE SYMPTOMS
Get an understanding of the trouble symptoms and check according to the inspection procedure chart.
Trouble symptomsInspection pro-
cedure No.Reference page
When the ignition key is turned to “ON” (engine stopped), the ABS warning lamp
does not illuminate.135B-12
Even after the engine is started, the ABS warning lamp remains illuminated.235B-13
After the ignition key is turned to “ON”, the ABS warning lamp blinks twice, and
when turned to “START”, it illuminates. When returned to “ON”, the lamp
flashes once, and then switches off.335B-13
When the ignition key is turned to “START”, the ABS warning lamp does not
illuminate.435B-14
Brake operation is abnormal535B-14
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 is not being applied. Because of this, when getting information from the customer,
check if the problem occurred while driving under such conditions as these.
(2) During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such
phenomena are due to intermittent changes in hydraulic pressure inside the brake line to prevent
the wheels from locking and is not an abnormality.
