Rear
REAR ABS WHEEL-SPEED SENSOR INSPECTIONInstallation Visual Inspection
1. Inspect for the following:
^ If there is any malfunction, replace the part.
1. Excessive looseness or play of the ABS wheel-speed sensor
2. Deformation of the ABS wheel-speed sensor
3. Deformation or damage of the ABS sensor rotor
Clearance Inspection
1. Remove the rear ABS wheel-speed sensor.
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 -13.9 (0.547).
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 it.
Clearance 1.46 mm (0.057 inch) or less
Sensor Output Value Inspection
Caution: Resistance inspection using other testers may cause damage to the ABS wheel-speed sensor internal circuit. Be sure to use the WDS or equivalent to inspect the ABS wheel-speed sensor.
1. Turn the ignition switch off.
2. Connect the WDS or equivalent to the DLC-2.
3. Select the following PIDs using the WDS or equivalent:
^ LR WSPD (LR wheel-speed sensor)
^ RR WSPD (RR wheel-speed sensor)
4. Start the engine and drive the vehicle.
5. Verify that the display of the WDS or equivalent shows the same value as the speedometer If there is any malfunction, replace the ABS wheel-speed sensor.
