Component Inspection

■ Wheel Speed Sensor Circuit Check 

1. Lift the vehicle.
2. Ignition switch 'ON'.
3. Turn the wheel by hand.
4. Measure waveform between signal terminal of the wheel speed sensor harness connector and chassis ground with oscilloscope.

   Specification  : High 1.4 ~ 2.0 V, Low 0.7 ~ 1.0 V

5. Is the measured waveform within specifications?

   YES 

   • Fault is intermittent caused by poor connection in wheel speed sensor harness (Front Left). Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Substitute with a known-good Wheel speed sensor and check for proper operation. If problem is corrected, replace Wheel speed sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
