INSPECTION

ABS Sensor
1) Check pole piece of ABS sensor for foreign particles or damage. If necessary, clean pole piece or replace ABS sensor.








2) Measure ABS sensor resistance.

CAUTION: If resistance is outside the standard value, replace ABS sensor with new one.

NOTE: Check ABS sensor cable for discontinuity. If necessary, replace with a new one.





Tone Wheel
1) Check tone wheel's teeth (44 pieces) for cracks or dents. If necessary, replace tone wheel with a new one.
2) Clearances (sensor gaps) should be measured one by one to ensure tone wheel and speed sensor are installed correctly.

ABS sensor clearance:
Front
0.9 - 1.4 mm (0.035 - 0.055 in)
Rear
0.7 - 1.2 mm (0.028 - 0.047 in)

NOTE:
- If clearance is narrow, adjust by using spacer (Part No. 26755AA000).
- If clearance is wide, check the outputted voltage then replace ABS sensor or tone wheel if the outputted voltage is outside the specification.





Output Voltage
Output voltage can be checked by the following method. Install resistor and condenser, then rotate wheel about 2.75 km/h (2 MPH) or equivalent.

NOTE: Regarding terminal No., please refer to ABS SENSOR.
