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 (RL) harness connector and chassis ground with oscilloscope.
Specification: High: 1.4 ~ 2.0V, Low: 0.7 ~ 1.0V
- Is the measured waveform within specifications?
YES
- Fault is intermittent caused by poor connection in wheel speed sensor harness (RL). 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.
