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.)
