The Braking Distance Is LongNFS0004U
CAUTION:
On slippery road surfaces, the stopping distance might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Disconnect VDC/TCS/ABS control unit connector to deactivate ABS. In this condition, check stopping dis-
tance. After inspection, connect connector.
OK or NG
OK >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-124, "Excessive ABS Func-
tion Operation Frequency" .
NG >>

Bleed air from the brake piping.

Check brake system.
The ABS Function Does Not OperateNFS0004V
CAUTION:
The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure the warning lamp turns off approximately 1 second after the ignition switch is turned on or when
driving.
OK or NG
OK >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-124, "Excessive ABS Func-
tion Operation Frequency" .
NG >> Perform self-diagnosis. Refer to BRC-96, "
OPERATION PROCEDURE" .
Pedal Vibration or ABS Operation Sound OccursNFS0004W
CAUTION:
Under the following conditions, when brake pedal is lightly depressed (just place a foot on it), ABS is
activated and vibration is felt. However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves [50 mm (1.97 in) or more]

When pulling away just after starting engine (at approximately 10 km/h (6MPH) or higher)
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sound occurs when the engine is started.
Does the symptom occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer to BRC-96, "
OPERATION PROCEDURE" .
2. SYMPTOM CHECK 2
Check symptom when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur when the electrical component (head lamp, etc.) switches are operated?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit (or its wir-
ing), and if there is, move it farther away.
NO >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-124, "
Excessive ABS Func-
tion Operation Frequency" .

Removal and InstallationNFS0004Y
COMPONENTS
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts and nuts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor motor. Remove any foreign
material and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in diagram (2 at shock absorbers and 1 at body panel). When installed, harness must not be
twisted. White line on harness (shaded part) must be visible from front.

REMOVAL
Front
Sensor rotor cannot be disassembled. To replace sensor rotor, replace hub bearing assembly. Refer to FA X - 4 ,
"Removal and Installation" in “Front Axle/Drive Shaft” in “FAX” section.
Rear

Follow procedure below to remove rear sensor rotor.
–Remove side flange. Refer to RFD-15, "SIDE OIL SEAL" in “Rear Final Drive” in “RFD” section.
–Using a bearing replacer (special service tool) and puller (commercial service tool), remove sensor rotor
from the companion flange.
INSTALLATION
Front
Sensor rotor cannot be disassembled. To replace sensor rotor, replace hub bearing assembly. Refer to FA X - 4 ,
"Removal and Installation" in “Front Axle/Drive Shaft” in “FAX” section.
Rear

Follow procedure below to install rear sensor rotor.
–Using a drift (special service tool), press rear sensor rotor onto
the side flange.
–Install side flange. Refer to RFD-15, "SIDE OIL SEAL" in “Rear

REMOVAL
1. Remove center console. Refer to IP-16, "CENTER CONSOLE" .
2. Remove harness connector.
3. Remove installation bolts. Remove yaw rate/side G sensor.
CAUTION:

Do not drop or strike the yaw rate/side G sensor, because it
has little endurance to impact.

Do not use power tool etc., because yaw rate/side G sensor
is weak for the impact.
INSTALLATION
To install, follow procedure for removal in reverse order.
CAUTION:

Do not drop or strike the yaw rate/side G sensor, because it has little endurance to impact.
