SYMPTOM DIAGNOSIS
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".

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.

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.

Is the steering angle within the specified range?
YES >> GO TO 4.
NO >> Perform the neutral position adjustment for the steering angle sensor again, GO TO 1.
4.ERASE THE SELF-DIAGNOSIS MEMORY
Erase the self-diagnosis memories of the ABS actuator and electric unit (control unit) and ECM.
 ABS actuator and electric unit (control unit): Refer to BRC-80, "
CONSULT-III Function".
 ECM: Refer to EC-113, "

FUNCTION DIAGNOSIS

System DiagramINFOID:0000000003766885
System DescriptionINFOID:0000000003766886
 Vehicle Dynamics Control system detects driver′s steering operation amount and brake pedal travel from
steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sen-
sor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stabil-
ity by controlling brake application to 4 wheels and engine output.
 During VDC operation, it informs driver of system operation by flashing SLIP indicator lamp.
 Electrical system diagnosis by CONSULT-III is available.
