Component Inspection
- Wheel Speed Sensor circuit check
- Lift the vehicle.
- Ignition "ON"& Engine "OFF".
- Turn the wheel by hand.
- 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
- Is the measured waveform within specifications?
YES
- Fault is intermittent, caused by poor connection in Wheel Speed Sensor harness (FL). Repair or replace as necessary and then 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.
