Rear Abs Wheel-Speed Sensor Inspection [AWD]: Notes

CAUTION:
  • Do not allow a magnetized tool such as a magnetized screwdriver to come into contact with the ABS sensor rotor. If the ABS sensor rotor becomes magnetized it will be unable to read the rear ABS wheel-speed sensor waveform correctly resulting in an ABS system malfunction to be determined and the inability to perform ABS control. If a magnetized object comes into contact with the ABS sensor rotor, it will be necessary to newly replace the rear drive shaft (ABS sensor rotor).
