## Installation Visual Inspection

1. Inspect for the following:

  • If there is any malfunction, replace the part.
  (1) Excessive looseness or play of the ABS wheel-speed sensor
  (2) Deformation of the ABS wheel-speed sensor
  (3) Deformation or damage of the ABS sensor rotor

## Clearance Inspection

1. Remove the rear ABS wheel-speed sensor.

2. Measure the distance between the rear ABS wheel-speed sensor installation surface and the ABS sensor rotor. This is dimension A.

3. Calculate the clearance between the rear ABS wheel-speed sensor and the ABS sensor rotor using the following formula:

  Clearance (mm {in}) = A -13.9 {0.547}

4. Verify that the clearance between the ABS sensor rotor and the rear ABS wheel-speed sensor is as indicated below.

  • If there is any malfunction, replace it.

  Clearance
  1.46 mm {0.057 in} or less

## 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 WDS or equivalent to inspect the ABS wheel-speed sensor.

1. Turn the ignition switch off.

2. Connect the WDS or equivalent to the DLC-2.

3. Select the following PIDs using the WDS or equivalent:

  • 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 WDS or equivalent shows the same value as the speedometer.

  • If there is any malfunction, replace the ABS wheel-speed sensor.
