ABS WARNING LAMP INSPECTION
35201200178
Check that the ABS warning lamp illuminates as
follows.
1. When the ignition key is turned to “ON”, the ABS warning
lamp illuminates for approximately 3 seconds and then
switches off.
2. When the ignition key is turned to “START”, the ABS
warning lamp remains illuminated.
3. When the ignition key is turned from “START” back to
“ON”, the ABS warning lamp illuminates for approximately
3 seconds and then switches off.
NOTE
The ABS warning lamp may remain on until the vehicle
reaches a speed of several km/h. This is limited to cases
where diagnosis code Nos.21 - 24 and 55 have been
recorded because of a previous problem occurring. In
this case, the ABS-ECU keeps the warning lamp
illuminated until the problem corresponding to that
diagnosis code can be detected.
4. If the illumination is other than the above, check the
diagnosis codes.

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.
