TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2006 July 2007 FX35/FX45
The Braking Distance is LongNFS000O0
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 E56 to deactivate ABS. In this condition,
check stopping distance. After inspection, connect connector.
OK or NG
OK >>
Bleed air from brake piping.

Check brake system.
NG >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "
Excessive ABS Function Operation Fre-
quency" .
The ABS Function Does Not OperateNFS000O1
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 2 seconds after the ignition switch is turned ON or when driv-
ing.
OK or NG
OK >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-53, "Excessive ABS Function Operation Fre-
quency" .
NG >> Perform self-diagnosis. Refer to BRC-25, "
Self-Diagnosis" .
Pedal Vibration or ABS Operation Sound OccursNFS000O2
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

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 engine is started.
OK or NG
OK >> Perform self-diagnosis. Refer to BRC-25, "Self-Diagnosis" .
