Sensor Output Value Inspection

CAUTION:
  • Resistance inspection using other testers may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS or equivalent to inspect the ABS wheel-speed sensor.
  1. Turn the ignition switch off.
  2. Connect the M-MDS or equivalent to the DLC-2.
  3. Select the following PIDs using the M-MDS or equivalent:
    • LF_WSPD

      (LF wheel-speed sensor)

    • RF_WSPD

      (RF wheel-speed sensor)

  4. Start the engine and drive the vehicle.
  5. Verify that the display of the M-MDS or equivalent shows the same value as the speedometer.
    • If there is any malfunction, replace the front ABS wheel-speed sensor.
