Sensor Output Value Inspection

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Performing the resistance inspection using a tester 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.

Switch the ignition to off.
Connect the M-MDS to the DLC-2.
Select the following PIDs using the M-MDS.
- WSPD_LF
  (LF wheel-speed sensor)
- WSPD_RF
  (RF 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 ABS wheel-speed sensor.
