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.

1. REMOVAL OF THE FRONT TOOTHED ROTOReRefer to GROUP Z-Hub and Knuckle.
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.

3-Axle Shaft.
Cautionr*
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
not perform normally.
10. REMOVAL OF REAR SPEED SENSORRemove the speed sensor bracket and rear axle spindle
installation nut, 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.

10. INSTALLATION OF REAR SPEED SENSOR (1) Teimn;rarily install the speed sensor to the rear axle
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 metal
objects.(2) Note the following points when connecting the speed
sensor cable, and secure the cable by the clip.
@I Secure the clip so that the white-painted part
(shaded in the illustration) of the speed sensor cableis not twisted.
@ Be sure that there is space (where shown in the
illustration) so that the trailing arm and speed
sensor cable do not contact, and then secure by the
clip.
Caution
Because there is the possibility of damage to the
cable during driving if the speed sensor cable and
the trailing arm come into contact, or if the speed
sensor cable is twisted, care must be taken regard-
ing this point.(3) Insert a feeler gauge into the space between the speed
sensor’s pole piece and the rotor’s toothed surface, andthen tighten the speed sensors at the position where
the clearance is the standard value.
Standard value:
0.3-0.9 mm (.012-.035 in.)
NOTECheck to be sure that there is no contact of the speed
sensor’s pole piece and the rotor’s toothed surface
when the rear hub assembly is slowly rotated one time.
If there is contact, it is probable that the rotor or the rearhub is installed incorrectly, recheck installation.

5. INSTALLATION OF FRONT SPEED SENSOR BRACKET
Assemble the speed sensor and the speed sensor bracket.
NOTE(1) The shape is different for the left and right speed
sensor brackets. Each bracket has an identification
symbol, so be sure to note these symbols
ahd. install
correctly.
FR: Indicates that the bracket is for the front speed
sensor.R: Indicates that the bracket is for the right wheel.
L: Indicates that the bracket is for the left wheel.
(2) Check to be sure, when installing the speed sensor to
the bracket, that the letters “FR” are visible.
4. INSTALLATION OF FRONT SPEED SENSOR(1) Temporarily install the speed sensor to the knuckle.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.(2) Note the following points when connecting the speed
sensor cable, and secure the cable by the clip.
@ Secure the cable by the clip so that the white-
painted parts of the blackened parts (in the illustra-
tion) of the speed sensor cable are within the rangeof the angles indicated by cross-section A-A and
cross-section B-B in the illustration.
@ Check to be sure that the white-painted part
(shaded in the illustration) of the speed sensor cableis not twisted.Caution
Because there is the possibility of damage to the
cable during driving if the speed sensor cable is
twisted, care must be taken regarding thispoint.
(3) Insert a feeler gauge into the space between the speed
sensor’s pole piece and the rotor’s toothed surface, and
then tighten the speed sensor at the position where theclearance is the standard value all around.Standard value:
0.3-0.9 mm (.012-.035 in.)
NOTE
If the clearance between the speed sensor’s pole pieceand the rotor’s toothed surface is not within the
standard value range, it is probable that the rotor is
incorrectly installed, recheck installation.
