2019 Toyota Landcruiser ABS fault.
This vehicle presented with a LHR wheel speed sensor fault. This vehicle already had the wheel speed sensor replaced and the rear wiring loom for the both rear speed sensors. 95% of the time it is one of those parts that fail. This time i got asked to get involed and within 15 mins we found a direction we could go towards. While monitoring my oscilloscope i found the LHR wheel speed sensor would get an interrupted signal every rotation. So technically it was reading correct but it had a "noise" in the circuit which was enough to trigger the fault. After my recommendation to inspect the rear wheel tone wheel we found evidence of our findings and confirmed the fault
