01683 - Wheel Speed Signals / Vehicle Speed

Possible Symptoms

  • ABS light On
  • ESP/ASR Light On

Possible Causes

  • WSS (Wheel Speed Sensor) readings from ABS module and VSS (Vehicle Speed Sensor) readings are not plausible
  • Wiring and/or Connector(s) from/to WSS faulty
  • WSS (Wheel Speed Sensor) Faulty
  • Wiring and/or Connector(s) from/to VSS (Vehicle Speed Sensor)
  • VSS (Vehicle Speed Sensor)

Possible Solutions

  • Check MVBs for live readings of VSS and WSS in various modules, including Engine, Transmission and ABS
  • Check WSS and VSS sensors and wiring and/or connector(s) from/to sensors

Special Notes

  • When found with missing WSS readings from one or more wheels verify:
    • The air gap in-between the WSS and the ABS pick-up wheel is correct.
    • The pick-up wheel (including metal ring on the wheel bearing or CV joint ring) aren't missing/damaged.
