ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)
 For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of vehi-
cles without ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
 For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as the
condition of vehicles without ABS, EBD system.

EXCESSIVE ABS FUNCTION OPERATION FREQUENCY
Diagnosis ProcedureINFOID:0000000003766852
1.CHECK START
Check front and rear brake force distribution using a brake tester. Refer to BR-45, "
General Specifications".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Check brake system.
2.CHECK FRONT AND REAR AXLE
Make sure that there is no excessive play in the front and rear axles.
 Front: Refer to FA X - 6 , "
Inspection".
 Rear: Refer to RAX-3, "
Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace malfunctioning components.
3.CHECK WHEEL SENSOR AND SENSOR ROTOR
Check the following.
 Wheel sensor installation for damage.
 Sensor rotor installation for damage.
 Wheel sensor connector connection.
 Wheel sensor harness inspection.
Is the inspection result normal?
YES >> GO TO 4.
NO >>  Replace wheel sensor or sensor rotor.
 Repair harness.
4.CHECK ABS WARNING LAMP DISPLAY
Make sure that the ABS warning lamp is turned off after the ignition switch is turned ON or when driving.
Is the ABS warning lamp illuminated?
YES >> Perform self-diagnosis.
NO >> Normal

FRONT WHEEL SENSOR : Removal and InstallationINFOID:0000000003766866
REMOVAL
Be careful with the following when removing sensor.
CAUTION:
 Do not twist sensor harness as much as possible, when removing it. Pull sensors out without pulling
sensor harness.
 Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-
ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.
INSTALLATION
Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
Refer to BRC-57, "
FRONT WHEEL SENSOR : Exploded View".
CAUTION:
 When installing, make sure there is no foreign material such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.

WHEEL SENSOR
 Completely push in rubber grommets of strut bracket and body bracket until they lock when install-
ing wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto
bracket with orange line on the harness facing bracket opening (mounting hole). There should be no
twists in the harness when installed.
