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.

(1)  Excessive play of the rear ABS wheel-speed sensor

(2)  Deformation of the rear ABS wheel-speed sensor

(3)  Deformation or damage of the ABS sensor rotor

(4)  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.

Clearance Inspection

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