OK or NG
OK >> GO TO procedure 3 “CHECK WHEEL SENSOR AND SENSOR ROTOR” of symptom1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
NG >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
Symptom 5: Pedal Vibration or ABS Operation Sound OccursEFS005UC
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.
lWhen shifting gears
lWhen driving on slippery road
lDuring cornering at high speed
lWhen passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
lWhen pulling away just after starting engine [at approximately 10 km/h (6 MPH) or more]
1.SYMPTOM CHECK 1
Check if there is pedal vibration or operation noise when the engine is started.
Do symptoms occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer toBRC-18, "
Self-Diagnosis".
2.SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO procedure 3²CHECK WHEEL SENSOR AND SENSOR ROTOR²of symptom 1. Refer to
BRC-33, "
Symptom 1: Excessive ABS Function Operation Frequency".
Symptom 6: ABS Warning Lamp Indication Is Not NormalEFS005UD
NOTE:
Lighting condition of ABS warning lamp refer toBRC-24, "
BASIC INSPECTION 3 ABS WARNING LAMP AND
BRAKE WARNING LAMP INSPECTION".
1.CHECK COMBINATION METER INDICATION

WHEEL SENSORS
REMOVAL
Pay attention to the following when removing wheel sensor.
CAUTION:
lAs much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.
lTake care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.
INSTALLATION
Pay attention to the following when installing wheel sensor. Tighten installation bolts and nuts to the specified
torques.
lWhen 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.
lWhen installing wheel sensor, be sure to press rubber grommets in until they lock at locations shown
above in figure. When installed, harness must not be twisted.
