NOTICE
• Handle the ABS components with care
since they have been accurately adjusted.
Keep them away from dirt and do not sub-
ject them to shocks.
• The front wheel sensor cannot be disas-
sembled. Do not attempt to disassemble it.
If faulty, replace with a new one.
• Keep any type of magnets (including mag-
netic pick-up tools, magnetic screwdrivers,
etc.) away from the front wheel sensor or
front wheel sensor rotor.
• Do not drop or shock the wheel sensor or
the wheel sensor rotor.
1. Check:
• Front wheel sensor "1"
Cracks/bends/distortion → Replace.
Iron powder/dust → Clean.
2. Check:
• Front wheel sensor rotor "1"
Cracks/damage/scratches → Replace the
front wheel sensor rotor.
Iron powder/dust/solvent → Clean.
TIP
• The wheel sensor rotor is installed on the inner
side of the wheel hub.
• When cleaning the wheel sensor rotor, be
careful not to damage the surface of the sensor
rotor.
3. Measure:
• Wheel sensor rotor deflection
Out of specification → Clean the installation
surface of the wheel sensor rotor and correct
the wheel sensor rotor deflection, or replace
the wheel sensor rotor.
Wheel sensor rotor deflection
limit
0.25 mm (0.0098 in)
