Wheel Speed Sensor Circuit Check
- Lift the vehicle.
- IG "ON".
- Turn the wheel by hand.
- Measure waveform between signal terminal of the Wheel Speed Sensor (FL) harness connector and chassis ground with oscilloscope.
Specification: High: approx. 11.5V, Low: approx. 10.9V (the Voltage could be varied with battery Voltage)
- Is the measured waveform within specifications?
YES
- Fault is intermittent caused by poor connection in Wheel Speed Sensor harness (FL). 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 FRONT WHEEL SPEED SENSOR and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
