Care must be taken not to scratch or scar the rotor’stoothed surface, and not to drop it.
If the rotor’s toothed surface is chipped or the rotor is
deformed, it might not be able to accurately sense the
wheel rotation speed and the system as a result might
__ r-14A¬ perform normally.
4. REMOVAL OF FRONT SPEED SENSORRemove the mounting bolts which hold the speed sensor
bracket to the knuckle, and then remove the speed sensor.

Caution
Be careful when handling the pole piece at the tip of
the speed sensor and the toothed edge of the rotor so
as not to damage them by striking against other parts.

INSPECTION
SPEED SENSOR CHECK
(1) Check whether any metallic foreign material has adhered to
the pole piece at the speed sensor tip, and, is so, remove it.Also check whether the pole piece is damaged, and, if so,
hreplace it with a new one.

NOTEThe pole piece can become magnetized because of the
magnet built into the speed sensor, with the result that
metallic foreign material easily adheres to it. Moreover, the
pole piece may not be able to function to correctly sense
the wheel rotation speed if it is damaged.
(2) Measure the resistance between the speed sensor termi-
nals.Standard value:
0.8-1.2 kQIf. the internal resistance of the speed sensor is not within
the standard value, replace it with a new speed sensor.
(3) Check the speed sensor cable for breakage, damage or
disconnection; replace with a new one if a problem is
found.
NOTE
When checking for cable damage, remove the cable clamppart from the body and then bend and pull the cable near
the clamp to check whether or not temporary disconnec-
tion occurs.
TOOTHED ROTOR CHECKCheck whether rotor teeth are broken or deformed, and, if so,
replace the rotor.
SERVICE POINTS OF INSTALLATION
11. INSTALLATION OF REAR SPEED SENSOR BRACKET
Assemble the speed sensor and the speed sensor bracket.
NOTEThe shape is different for the left and right speed sensor
brackets. Each bracket has an identification symbol, so be
sure to note these symbols and install correctly.
R: Indicates that the bracket is for the right wheel.
L: Indicates that the bracket is for the left wheel.
