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 (E)].)

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.)
