Component Inspection

Component Inspection

1. Lift the vehicle.
2. Ignition "ON".
3. Turn the wheel with hand.
4. Measure waveform between terminal "2" of the wheel speed sensor harness connector and chassis ground.
A. Specification: High : 1.18 - 1.68V, Low : 0.59 - 0.84V




5. Is the measured waveform within specifications ?
YES
1) Fault is intermittent caused by poor connection in wheel speed sensor harness (RL) and/or HECU's connector or was repaired and HECU memory was not cleared. Go to "Verification of Vehicle Repair" procedure.
NO
1) 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.
