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 to inspect the ABS wheel-speed sensor.

Turn the ignition switch off.
Connect the M-MDS to the DLC-2.
Select the following PIDs using the M-MDS:
- LR_WSPD
  (LR wheel-speed sensor)
- RR_WSPD
  (RR wheel-speed sensor)
Start the engine and drive the vehicle.
Verify that the display of the M-MDS shows the same value as the speedometer.
- If there is any malfunction, replace the rear ABS wheel-speed sensor.
