1. Inspect the following items:

- If there is any malfunction, replace the applicable part.

a. Excessive looseness or play of the rear ABS wheel-speed sensor

b. Deformation of the rear ABS wheel-speed sensor

c. Deformation or damage of the rear ABS sensor rotor

Clearance Inspection

1. Verify the clearance between the rear ABS sensor rotor and the rear ABS wheel-speed sensor.

- If there is any malfunction, check for improper installation, and replace if necessary.

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.

1. Turn the ignition switch off.

2. Connect the M-MDS to the DLC-2.






3. Select the following PIDs using the M-MDS:

- LR_WSPD
(LR wheel-speed sensor)
- RR_WSPD
(RR wheel-speed sensor)

4. Start the engine and drive the vehicle.

5. 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.
