Is the measured waveform within specifications?
 | ▶ Fault is intermittent caused by poor connection in wheel speed sensor harness (RL). Go to "Verification of Vehicle Repair" procedure. |
 | ▶ 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. |
