REAR ABS WHEEL-SPEED SENSOR INSPECTION

Sensor Output Value Inspection

CAUTION:

• Resistance inspection using other testers may cause damage to the rear ABS wheel-speed sensor internal circuit. Be sure to use the M-MDS to inspect the rear ABS wheel-speed sensor.

1. Switch the ignition off.

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

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

• WSPD_SEN_LR (LR wheel-speed sensor)

• WSPD_SEN_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 rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

Installation Visual Inspection

1. Inspect for the following:

• If there is any malfunction, repair or replace the part.

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

b. Deformation of the rear ABS wheel-speed sensor

c. Deformation or damage of the ABS sensor rotor

d. Adhering foreign matter

Clearance Inspection

Preparation prior to inspection

1. Remove the rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

2. Remove the wheel hub component. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION.)

3. Install the rear ABS wheel-speed sensor to the removed wheel hub component, and tighten to the specified torque.

Tightening torque

• 8—10 N·m {82—101 kgf·cm, 71—88 in·lbf}

Clearance Inspection

1. Measure the gap between the rear ABS wheel-speed sensor and ABS sensor rotor using a feeler gauge.

• If not within the specification, replace the rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

Clearance

• 0.810—1.443 mm {0.0319—0.0568 in}

Servicing after inspection

1. Remove the rear ABS wheel-speed sensor from the wheel hub component.

2. Install the wheel hub component. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION.)

3. Install the rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

4. Inspect the rear wheel alignment. (See REAR WHEEL ALIGNMENT.)
