6. REMOVAL OF RELAY BOX COVER
Insert the tip of a screwdriver into the space between the
hydraulic unit and the relay box cover and use it to open
the tab at one place, and then remove the cover.
10. REMOVAL OF HYDRAULIC UNIT Remove the bracket
B, C and D installation bolts, and then
take out the hydraulic unit downward.
Caution 1. The hydraulic unit is heavy, and so care should be
taken when removing it.
2. The hydraulic unit is not to be disassembled; its
nuts and bolts should absolutely not be loosened.
3. The hydraulic unit must not be dropped or other-
wise subjected to impact shocks.
4.The hydraulic unit must not be turned upside downor laid on its side.
INSPECTION
Check whether there is continuity between terminals when
there is no current flow at each relay and when there is
current flow.

SERVICE POINTS OF REMOVAL 1. REMOVAL OF THE FRONT TOOTHED ROTOR Refer to GROUP
26-Hub and Knuckle.
Caution Care must be taken not to scratch or scar the rotor’s
toothed 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.
4. REMOVAL OF FRONT SPEED SENSOR Remove 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.
6. REMOVAL OF REAR TOOTHED ROTOR For FWD vehicles, remove together with the rear axle
assembly, as shown in the figure, and then remove the rear
toothed rotor from the rear axle assembly.
Caution
Care must be taken not to scratch or scar the rotor’s
toothed 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 SENSOR Remove 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.
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, replace it with a new one.

NOTE
14AOO46
The 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. 14NO295

00
14AOO47
ITSB RevisionStandard value:
0.8-1.2 ks1
If the internal resistance of the speed sensor is not within
the standard value, replace it with a new speed sensor.
(3) Measure the resistance between each terminal on the speed sensor and the sensor body.
Standard value: 100
kfI or more
When the insulated resistance is not within the standard
value, replace the sensor.
(4) Check the speed sensor cable for breakage, damage or discorrnection;
replace with a new one if a problem is
found.
NOTE
When checking for cable damage, remove the cable clamp part from the body and then bend and pull the cable near
the clamp to check whether or not temporary disconnection occurs.
TOOTHED ROTOR CHECK Check 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 brack-
et.
NOTE
The shape is different for the left and right speed sensorbrackets. 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.
