Component Inspection

1. Lift the vehicle.
2. Ignition "ON".
3. Turn the wheel with hand.
4. Measure waveform between terminal "FL, FR: 1, RL, RR: 1" of the wheel speed sensor harness connector and chassis ground.

   Specification: Approx. High: 1.05 V, Low: 0.525 V

5. Is the measured waveform within specifications?

YES 

• Fault is intermittent caused by poor connection in wheel speed sensor harness. 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.
