Component Inspection

Wheel speed sensor circuit check
1. Lift the vehicle.
2. IG "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 : 1.18~1.68V, Low : 0.59~0.84V

5. Is the measured waveform within specifications?
  YES
  - Fault is intermittent caused by poor connection in FRONT WHEEL SENSOR RH. Go to VERIFICATION OF VEHICLE REPAIR procedure.
  NO
  - Substitute with a known-good FRONT WHEEL SENSOR RH and check for proper operation. If problem is corrected, replace FRONT WHEEL SENSOR RH and then go to VERIFICATION OF VEHICLE REPAIR procedure.
