Are there foreign matter,
breakage or damage at the tip
of ABS wheel speed sensor or
magnetic encoder?
Remove dirt
throughly. Also
replace the ABS
wheel speed sen-
sor or magnetic
encoder as a unit
with hub unit bear-
ing if it is broken or
damaged.

electric components installed
correctly?
Go to step 12.Install the radio
wave devices and
electric compo-
nents properly.

warning light re-
mains on at this
time, it is normal.
Drive the vehicle at
more than 12 km/h
(7 MPH) in order to
turn ABS warning
