The Braking Distance is LongNFS0002G
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 ABS actuator and electric unit (control unit) connector to deactivate ABS. In this condition, check
stopping distance. After inspection, connect connector.
OK or NG
OK >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-32, "Excessive ABS Func-
tion Operation Frequency" .
NG >>
Bleed air from the brake piping.
Check brake system.
The ABS Function Does Not OperateNFS0002H
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 warning lamp turns off approximately 1 second after the ignition switch is turned on or when driv-
ing.
OK or NG
OK >> GO TO 3. CHECK WHEEL SENSOR AND SENSOR ROTOR in BRC-32, "Excessive ABS Func-
tion Operation Frequency" .
NG >> Perform self-diagnosis. Refer to BRC-19, "
OPERATION PROCEDURE" .
Pedal Vibration or ABS Operation Sound OccursNFS0002I
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 (6 MPH) 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-19, "
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-32, "
Excessive ABS Func-
tion Operation Frequency" .

Does the symptom occur?
YES >> GO TO 2.
NO >> Perform self-diagnosis. Refer to BRC-53, "
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-69, "
Excessive ABS Func-
tion Operation Frequency" .
The Vehicle Jerks Around During TCS/ABS ControlNFS0003M
1. CHECK ENGINE SPEED SIGNAL
Conduct CONSULT-III ABS actuator and electric unit (control unit) “Data Monitor”.
Is the speed during idling 400 rpm or higher?
YES >> GO TO 3.
NO >> GO TO 2.
2. CHECK ECM SELF-DIAGNOSIS RESULT ITEM
Perform ECM self-diagnosis.
Are self-diagnosis items displayed?
YES >> Check the corresponding items. Refer to EC-81, "TROUBLE DIAGNOSIS" in “Engine Control
(EC section)”.
NO >> GO TO 3.
3. SYMPTOM CHECK 1
Check if the vehicle jerks during TCS/ABS control.
OK or NG
OK >> INSPECTION END
NG >> GO TO 4.
4. CHECK A/T SELF-DIAGNOSIS RESULT ITEM
Perform A/T self-diagnosis.
OK or NG
OK >> GO TO 5.
NG >> Check the corresponding items. Refer toAT- 4 0 , "
TROUBLE DIAGNOSIS" in “A/T”.
