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: (See PID/DATA MONITOR INSPECTION.)

• WSPD_SEN_L/R (LR ABS wheel-speed sensor)

• WSPD_SEN_R/R (RR ABS 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 the following items:

• Excessive play of the rear ABS wheel-speed sensor

• Deformation of the rear ABS wheel-speed sensor

― If there is any malfunction, replace the rear ABS wheel-speed sensor. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION.)

• Deformation or damage of the ABS sensor rotor

― If there is any malfunction, replace the wheel hub component. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [2WD].)

Clearance Inspection

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

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-14 {0.55}

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