Rear Abs Wheel-Speed Sensor Removal/Installation [AWD]: Notes

2023 Mazda CX-5 SSECTION 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 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).
  1. Switch the ignition ON (engine off).
  2. Release the electric parking brake.
