10 CHECK ABS WHEEL SPEED SENSOR OR
MAGNETIC ENCODER.
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.
Go to step 11.
11 CHECK CAUSE OF SIGNAL NOISE.
Make sure the radio wave devices and electric
components are installed correctly.
Are the radio wave devices and
electric components installed
correctly?
