Rear ABS Wheel-Speed Sensor Inspection

REAR ABS WHEEL-SPEED SENSOR INSPECTION

Installation Visual Inspection

1. Inspect the following items:

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

a. Is there looseness or play in the sensor installation?

b. Has the sensor been deformed?

c. Is there deformation of or damage to 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 rear 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-15 mm {0.59 in}

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, verify the installation condition and replace if necessary.

Clearance
- 0.3-1.1 mm {0.02-0.04 in}

Sensor Output Value Inspection

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.

1. Switch the ignition to off.

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






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

- WSPD_LR
(LR wheel-speed sensor)
- WSPD_RR
(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 ABS wheel-speed sensor.
