• 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 runout
Out of specification Clean the installation
surface of the wheel sensor rotor and correct
the wheel sensor rotor runout, or replace the
wheel sensor rotor.
